| 12/14/2005 | Lake George turns green | |
| Contacts | www.abc.net.au/southeastsa/stories/s1529182.htm | Peri Coleman | We have the Blue Lake in Mount Gambier and the Pink Lake in the Coorong. Beachport can now join the club, because Lake George has turned green. And it is turning fishermen, swimmers and tourists away in droves. There was once a time when a time when people flocked to the shores of Lake George to waterski, canoe, sail, fish, swim or do some bird observing. But if you have fond memories of Lake George, chances are they not from this century. These days the lake is far from alluring. “It’s certainly a queer colour to what it used to be,” reflects local recreational fisherman Frank Corigliano. “And polluted to the eyeballs with whatever.” Another local fisherman, John Galway, remembers a time when the water was crystal clear and you could see the bottom of the lake – and the fish on your line – even at the deepest point. “You can’t see your hand three inches under the water,” he says of its current state. Mount Gambier ABC has a web page devoted to the issue of why Lake George has turned green. Issues raised include the effects of the "south-east drains", nutrients, salinity, depth, the maintenance of the artificial channel that connects the lake to the sea (necessary since the lake became the repository of all the south-east drainage waters). |

| 11/18/2005 | US Senate approves water bill providing aid to saline Walker Lake, Nevada, US | |
| Contacts | RENO, Nev. (AP) - The U.S. Senate has approved a multimillion-dollar package of water- and flood-control projects that includes $95 million to help save imperiled Walker Lake. "With this funding, we are creating a way for everyone to work together and partner with our university experts to solve some of the toughest natural resource challenges in the country," Sen. Harry Reid said of Monday's passage. "This is a balanced and comprehensive approach to managing land and water in the Walker River basin. It will also mean the beginning of real efforts to save Walker Lake and protect one of our state's most valuable natural resources." The amendment - originally included in the 2002 farm bill - releases $70 million to the University of Nevada, Reno, for an agricultural and natural resources center to work on research, restoration and educational activities along the Walker River. Another $10 million will provide for a water lease and purchase program for the Walker River Tribe; $10 million will go toward eradication of the thirsty tamarisk, which sucks up water from native plants, and $5 million for fishery improvements. Reid, D-Nev., Sen. John Ensign, R-Nev., and Rep. Jim Gibbons, R-Nev., have been working to create a means to release the funding, which was stripped from another spending bill earlier this year. Louis Thompson, chairman of the Walker River Working Group, said he's hopeful the money will significantly aid efforts to reverse degradation of a lake in "dire straits." Water levels at Walker Lake have dropped 150 feet over the last 120 years because of water diversions, mainly for agricultural irrigation. "I hope it will help the process," Thompson said. "If we don't have another good water year - hopefully better than last year - I'm fearful we'll lose the fishery next summer." Another $3.5 million is included in the energy and water bill for the Army Corps of Engineers to continue the planning and design of the Truckee River Flood Control Project. At an estimated cost of $350 million, the project is being pursued to avoid floods on the Truckee River of the type that caused nearly $700 million in damage in January 1997. |

| 10/26/2005 | XI International Symposium on Rotifera, March 11-18, 2006, UNAM, Mexico City | |
| Contacts | www.iztacala.unam.mx/rotiferaXI/ | sarma@servidor.unam.mx | Rotifers are small (<1 mm) but beautiful invertebrates, harmless to mankind. Their use as model organisms in teaching courses of biology, as a scandalous group in evolutionary ecology, as baby food in aquaculture and as sensitive indicators of water quality has been widely recognized. The tradition of a periodic meeting of the international rotifer workers initiated by the late Agnes Ruttner-Kolisko has had a stimulatory influence on Rotifer Research. So far nine countries have hosted these symposia (Austria (twice), Belgium, Italy, Poland, Spain, Sweden, United Kingdom, USA and Thailand). The present XI International Rotifer Symposium will be hosted by Mexico under the auspices of the Campus Iztacala of the National Autonomous University of Mexico. It provides an opportunity to interact with an international community of researchers on various aspects of Rotifera. We therefore cordially invite you to participate in this symposium. |

| 10/16/2005 | Impact of mining on salt lakes in Western Australia | |
| Contacts | brian.timms@newcastle.edu.au | I am concerned about the effect of added salt water from the dewatering of mines on various large salt lakes in the Goldfields of Western Australia. The water added is commonly of the order of >250 g/kg and enough to wet significant areas of impacted lakes. It is sanctioned on the grounds that the lakes are already quite saline, and that the fauna, when present, is euryhaline, but there is very little research on the consequences of these actions. Enough is now known to warrant a review of the environmental effect of this disposal of mine waters. The problem can be itemised into five issues, listed in increasing order of probability: 1. The salt accumulation may be sufficient to exceed the hatching tolerances of cysts of component crustaceans. Should the receiving lake be small or the affected area be large, then there could be a problem. 2. If the area affected is transformed into a permanent lake, then local fauna (Parartemia spp., ostracods, copepods) is disadvantaged as it is adapted for episodic waters. Worse still, exotic fauna (e.g. Artemia spp.) are advantaged by this and are already present in WA and spreading inland. 3. Heavy metals may occur in lake fauna and be passed up the food chain. 4. Salt accumulation may be sufficient to prevent the lake having a hyposaline stage when it fills from a rare cyclonic input. Salinaland lakes have a largely unstudied and apparently endemic hyposaline fauna. A 10 g/L salt increase is of little effect to a hypersaline fauna, but catastrophic to a hypsosaline fauna. 5. Deposited salt may be reworked during a filling event and left in the lake inlets. This is known to reduce biodiversity in terminal salt lakes, as much of their fauna comes from entering creeks. The first two possibilities seem not to be an issue at present because the lakes affected are large and remote (but we cannot be sure because of secrecy in the industry), some evidence was presented for the third and fifth possibility at the ISSLR Meeting in Perth and I expand upon the fourth possibility in a forthcoming paper in Hydrobiologia (VOL 552: 5-19).

| 10/10/2005 | Lake Bonney to discharge to sea | |
| Contacts | Coastal residents of South Eastern South Australia are concerned about the State government's plans to allow Lake Bonney to drain to sea again, according to the "Border Watch" newspaper. Lake Bonney, a shallow coastal lake has been polluted by discharge from the Kimberly-Clark Australia (KCA) factory. KCA has an indenture with the State government allowing the discharge to continue until 2016. The lake's water quality is now so poor that fishing and boating are no longer undertaken on the lake. Main polluting factors include turbidity, nutrients and organochlorine compounds. The current proposal is to allow the lake to discharge through Buck's Lake to Gerloff Bay. Local residents are concerned about the possible impacts of the polluted waters on coastal ecosystems. However the Environment Protection Authority has said that it simply wants to reinstate a natural flow path, reinvigorate Buck's Lake anddevise a plan for water levels in Lake Bonney. |

| 9/21/2005 | Tragic death of Ekkehard Vareschi and wife by falling tree | |
| Contacts | We regret announcing untimely death of Prof Ekkehard Vareschi and his wife at the Momela Lakes Reserve caused by a falling tree last Saturday while asleep in their car roof top tent. Prof. Vareschi had returned with his wife to Africa to spend a year studying Kenyan and Tanzanian soda lakes in his last year before retirement. His important work on Lake Nakuru stands as the most complete ecosystem analysis of a African saline lake to date. Vareschi, E. (1978). “Ecology of Lake Nakuru (Kenya).1.

| 7/9/2005 | Drying Lake Kills 10000 Turtles | |
| Contacts | brian.timms@newcastle.edu.au | The Paroo, southwest Queensland, Australia, is in its fifth year of drought. The episodic saline lakes like L. Wyara have long since dried, but the large, normally subsaline Lake Numalla dried in June this year for the first time in 23 years and only the third time since 1900. As it dried its waters salinised, reaching >100,000 mg/L. Massive bluegreen algal blooms of Arthospira sp. persisted for months. Invertebrate diversity collapsed many months ago and over 10,000 Murray River Turtles died this May. It is not known what killed them: probably not the greatly increased salinity per se, but maybe the collapse of their food chain or perhaps they succumbed to the algal poisons. It is believed this is a natural event. Hopefully the lake will be recolonised again from permament waterholes of the Paroo River, when the lake fills from a river flood. This is unlikely to occur until the present and persistent El Nino conditions give way to a La Nina event. I will be presenting pictures of this lake and its turtles at the forthcoming International Conference on Salt Lakes in Perth, Australia. |

| 7/5/2005 | Qinghai Lake the site of avian flu outbreaks | |
| Contacts | The lake is the location of the recent outbreak of deadly avian influenza strain H5N1, where the death of over 6,000 migratory waterbirds has been reported since early May, with mainly Barheaded Goose, Great Cormorant, Ruddy Shelduck, Great Blackheaded Gulls being reported dead. Attached for your reference is a report from Xinhua News Agency of July 2, 2005 which indicates that the outbreak may finally be under control. Bird Flu Outbreak in Qinghai Under Control A spokesperson with the Ministry of Agriculture said Friday that the bird flu outbreak in northwest China's Qinghai Province has been "brought under control." Jia Youling, also director-general of the ministry's Veterinary Bureau, said the number of migrant birds killed by the disease has dropped to about 20 a day since June 8. Thus far, more than 6,000 migratory birds have died since the disease was reported on May 4. Jia said the ministry has reported the latest developments to relevant international organizations. The governments at all levels in China attach great importance to the disease's prevention and control and related departments have taken many measures to prevent it. Since the bird flu outbreak was reported in Qinghai, the local government has done a lot to prevent the epidemic from spreading, he said, adding that no fowl or human beings have been infected so far. Jia said his ministry is studying and testing the virus drawn from the birds killed by the fatal disease in Qinghai, and the result will be reported to concerned international organizations as soon as possible. China has provided five viral strains to the World Health Organization (WHO) since bird flu cases were reported in the country last year. The Ministry of Agriculture hopes for closer cooperation with international organizations and welcomes international experts to Chinese labs for study, he said. The WHO has asked China to test some of the birds in the area to determine if any species were infected with the virus. Each summer, some 189 species of birds flock to Qinghai Lake, a mating ground for migratory birds, before heading south and west. Qinghai Lake has become a popular tourist attraction. In late May, more than 1,000 wild birds, including geese and gulls, were killed by the H5N1 flu strain in Qinghai. In Asia, at least 54 people have died so far this year after being infected by sick birds, reports said. (Xinhua News Agency July 2, 2005) |

| 6/29/2005 | Bugs thrive amid arsenic in salt pan | |
| Contacts | SCIENTISTS HOPE LAKE FINDINGS WILL LEAD TO CLUES ABOUT OTHER PLANETS By Glennda Chui Mercury News In one of the hottest, saltiest, nastiest places on Earth, Bay Area researchers have found microbes that live -- and thrive -- on arsenic. This hardy community, at Searles Lake in California's Mojave Desert, is apparently the first known ecosystem based on the toxic element. By studying how it works, scientists hope to find ways to clean up arsenic pollution in drinking water and aid the search for life in the harsh environs of other planets. ``It's very cool,'' said Derek Lovley, a microbiologist at the University of Massachusetts-Amherst who was not involved in the study. ``You think of arsenic as being toxic and of microbes, just like humans, trying to find a way of detoxifying it,'' he said. But in this case, Lovley said, ``the organisms are using arsenic the same way we use oxygen'' to carry out respiration. A team led by microbiologist Ronald Oremland of the U.S. Geological Survey in Menlo Park reported the discovery last month in the journal Science. ``This environment that I basically thought was going to be dead was very, very active,'' Oremland said. ``It's full of poison, and we found bugs that can live in the presence of as much salt as you can get.'' Salt pan Searles Lake is a salt pan -- a thin layer of briny liquid covered by a salty crust. It's one of a chain of lakes on the east side of the Sierra Nevada that has repeatedly filled and dried up over the past 20,000 years, leaving a high concentration of minerals behind. Mining companies pump dense brine from the lake and use it to produce boric acid, borax and other products. Collectors find spectacular mineral formations along its shores. But it's the last place anyone would expect to find life. Summer temperatures around the lake top 100 degrees; temperatures in the brine are even higher, with the salt crust acting as a lid to trap heat. The water is 10 times saltier than the ocean, highly alkaline and contains 29,000 times the level of arsenic allowed in drinking water. Until a decade ago, no one thought living things could use arsenic as a source of energy. The first evidence to the contrary was found by Dianne Ahmann, now at the Colorado School of Mines. Since then, more than two dozen microbes have been caught respiring arsenic. Getting energy ``The thing that's fascinating about these things is that we're very familiar with breathing in air, burning the sandwich we had for lunch to get energy to run around a track,'' said James Hollibaugh, a microbial ecologist at the University of Georgia. ``These organisms have evolved ways of getting energy from processes that don't require free oxygen. In fact they probably evolved first, and some of these processes may be extremely ancient.'' Dianne Newman, a geomicrobiologist at the California Institute of Technology, said, ``To my knowledge it's the first time an entire ecosystem, a whole lake, has been shown to be driven by an arsenic cycle in this way. And furthermore, this particular environment is weird.'' By studying life in such harsh places, scientists hope to find clues to what life might look like on other planets. ``You can make the argument that Searles Lake is an analog of what might have occurred on the surface of Mars when water was more abundant,'' Oremland said. His work is partly funded by the National Aeronautics and Space Administration's astrobiology program, which investigates the potential for life elsewhere in the universe. These arsenic-swilling microbes could also help scientists figure out how to clean up contamination in places such as Bangladesh, where tens of millions of people are at risk of drinking arsenic-tainted water. Arsenic is not just a poison; it's also linked to several forms of cancer. Most arsenic pollution is natural, although man-made chemicals also contribute. Arsenic in groundwater is also a problem in parts of the American West, including Nevada, Utah and southeastern California, according to Navin Kumar C. Twarakavi of the University of Alaska-Fairbanks. Treating water to remove arsenic can be expensive, and scientists would like to find a helpful microbe that changes the toxic form of arsenic into harmless ones. The Searles Lake microbes are unlikely to help, Oremland said, because they're adapted to living in harsh conditions and could not survive in pure, fresh water. But by understanding how they work, he said, researchers may be able to find -- or design -- other bugs that will do the job. |

| 6/29/2005 | Morocco adds 20 new Ramsar sites including salt lakes, works, lagoons, and marshes | |
| Contacts | ramsar.org/wn/w.n.morocco_20.htm | The Ramsar Secretariat has the pleasure to announce that the Kingdom of Morocco has designated 20 new Ramsar sites throughout the country and updated the information on its four existing sites. The total area of its Ramsar sites now amounts to 272,010 hectares and covers a variety of wetland types, including some of which are identified as being under-represented in the List of Wetlands of International Importance, and which Parties should give high priority to designating: these include mountain wetlands and seagrass beds. The Aguelmams Sidi Ali -Tifounassine and Lacs Isly-Tislite sites, for instance, comprise a complex of mountain lakes among which are two of the highest lakes in North Africa, which are situated at more than 2,000m in the Haut Atlas mountain range and are among the southernmost representatives of the lacustrine mountain ecosystems of the temperate paleo-arctic bioregion. Many sites, such as the Complexe du bas Loukkos, the Embouchure de l'oued Dr'a, Embouchure de la Moulouya, Embouchures des oueds Chbeyka-Al Wa'er and Zones humides de l'oued El Maleh comprise river estuaries and salt marshes which play a very important role as refuge, resting and wintering sites for migratory birds, many of which are endangered (Marbled Teal Marmaronetta angustirostris, Ferruginous duck Aythya nyroca, Ruddy Shelduck Tadorna ferruginea and Audouin's Gull Larus audouinii). On the other hand, some coastal sites exhibit great natural beauty, with their inclusion of marine lagoons, sea cliffs, sandy beaches and rocky shores, harbouring high invertebrate, mollusk, planktonic and mammalian biodiversity, and hosting charismatic species such as the monk seal, loggerhead turtle and different dolphin species. Among these sites, one should mention the Cap des Trois Fourches, Archipel et dunes d'Essawira, Baie d'Ad-Dakhla, Marais et côte du Plateau de Rmel and the Sebkha Bou Areg. A number of sites also include artificial wetland types, such as dam reservoirs, oases associated with irrigated palm plantations, and salt works, which play an important socio-economic role and still host some significant species such as endemic fish and plants, or waterbirds, such as waders. These include the Barrage Al Massira, Barrage Mohammed V, Complexe de Sidi Moussa-Walidia, Moyenne Dr'a, Oasis du Tafilalet and Sebkha Zima. Some sites are relatively pristine, such as the Zones Humides de Souss-Massa, which are part of a national park, while others including the Complexe du bas Tahaddart have suffered from high rates of development and are therefore in more need of stringent conservation measures. We would like to congratulate again the Kingdom of Morocco for its efforts towards the implementation of the Ramsar Convention and recognize the support for these site designations provided by the WWF Global Freshwater Programme and the WWF Mediterranean Programme Office (MedPo). |

| 6/17/2005 | Great Salt Lake Rising Again | |
| Contacts | After years of drought, Salt Lake rising By JENNIFER DOBNER ASSOCIATED PRESS WRITER BRIGHAM CITY, Utah -- The water in the Great Salt Lake has begun rising again after years of drought, changing the landscape and starting to submerge one of Utah's best-known artifacts: an enormous earth sculpture called the Spiral Jetty. The six years of drought had allowed the curious to flock to the lakeside to see the 1,500-foot-long, salt-encrusted spiral that Robert Smithson built in 1970 using backhoes to pile up rock and earth. For decades before the dry spell, the jetty had largely been just out of sight beneath the surface of the salty water. Thanks to a winter of record snowfall, it's not just the spiral Jetty that is changing. "Change in lake levels can produce significantly more of a change than you'd expect," says Maunsel Pearce, chairman of the Great Salt Lake Alliance, a consortium of conservation groups with interests in the lake. "You really need to see it to believe it." Sandbars exposed during the drought are now covered with water. Wetlands that had dried into sheets of cracked mud and thin dry grasses are now soggy marshes sprouting thick vegetation. Water also is inching back toward Antelope Island, although boat docks there remain beached. The lake's elevation averages about 4,200 feet above sea level, a level at which water spreads out across about 1,700 square miles, according to data kept since 1875 by the U.S. Geological Survey. But the drought that began in 1999 dropped the surface by about 6 feet, shrinking the lake to just 950 square miles. As of Saturday, it had gone back up a bit less than 4 feet, according to a USGS Web site. Such fluctuations are part of what makes the lake beautiful, says Lynn de Freitas, executive director of Friends of the Great Salt Lake. Each climate pattern changes the lake and people's perception of it, she said. "I guess my excitement is that the lake has the ability to breathe. Those droughts are part of the natural cycles of the lake," she said. The Great Salt Lake is a remnant of the ancient Lake Bonneville, which more than 12,000 years ago covered some 20,000 square miles of what is now Idaho, Utah and Nevada. Although just glimmer of its former self, the Great Salt Lake still is the world's fourth largest "terminal lake," where water flows in but doesn't flow out. Water delivered to the lake by four rivers is lost only through evaporation, which concentrates its mineral content, leaving behind a harsh solution in which only salt-tolerant species of brine shrimp, bacteria and algae can survive. Mineral companies extract selenium and magnesium from the lake bed. Commercial fishermen harvest brine shrimp. Each of those industries and recreational users were affected by the drought and will be again by the rising water, de Freitas notes. Rising water in the north arm of the lake will dilute the salty water where the Spiral Jetty sits and stimulate bacterial growth that turns the water pinkish-red, offering a different vision of the sculpture, de Freitas said. "The drama of the ability to see the jetty, I think now is actually improved," she said. "Now the water and is coming up and lapping at the jetty and even though you're slogging through the water, there's still a vague visible presence. I think people will find it more in keeping with the photographs they've seen." |

| 5/24/2005 | IUSS Conference on Salinization - September 19-22 Budapest | |
| Contacts | www.mozaik.hu/iuss/ | Salinization of land and waters is a widespread problem that has serious consequences. Although salinization is a natural process, human-induced salinization has far-reaching negative effects. In spite of the fact that there are similarities in salt-affected lands all over the world, many differences occur in their formation processes and characteristics. Salinization of agricultural lands can be prevented if the process is better understood. There are two aspects of salinization that call for special attention: -if the accumulation of sodium is not accompanied by large concentrations of soluble salts, the physical properties, and the resulting soil-water relationship, become a major obstacle in cultivation. -improper irrigation will typically result in off-site effects, and therefore cause not only physical and financial, but also political-societal conflicts. The study of salt-affected soils is rather advanced and represents the forefront of soil research. Hopefully the upcoming meeting will make an important contribution towards solving the problems related to salinization. |

| 5/19/2005 | Surface Elevation of Dead Sea Continues to Decline | |
| Contacts | www.msnbc.msn.com/id/7902962/ | For Dead Sea, a slow death Sea’s water level dropping as Jordan River goes dry By John Ward Anderson The Washington Post Updated: 3:48 a.m. ET May 19, 2005 EIN GEDI, Israel - When the Ein Gedi Spa opened in 1986 to pamper visitors with massages, mud wraps and therapeutic swims, customers walked just a few steps from the main building to take their salty dip in the Dead Sea. Nineteen years later, the water level has dropped so drastically that the shoreline is three-quarters of a mile away. A red tractor hauls customers to the spa's beach and back in covered wagons. "The sea is just running out, and we keep running after it," said Boaz Ron, 44, manager of the resort. "In another 50 years, it could run out another kilometer," or more than half a mile. It may sound redundant, but the Dead Sea, one of the world's cultural and ecological treasures, is dying. In the last 50 years, the water level has dropped more than 80 feet and the sea has shrunk by more than a third, largely because the Jordan River has gone dry. In the next two decades, the sea is expected to fall at least 60 more feet, and experts say nothing will stop it. |

| 5/12/2005 | Waters from saline Devils Lake to be diverted into Canada | |
| Contacts | By FRANK MCKENNA Published: May 12, 2005 in New York Times (Op Ed) A CRISIS looms on the United States border with Canada, and it could easily be averted with some research and a little patience. The problem stems from a body of water in North Dakota known as Devils Lake. The lake has no natural drainage, and because North Dakota has drained surrounding wetlands, it has risen 26 feet since 1993, flooding nearby communities. In Canada, we are sympathetic to the plight of the lake's neighbors, but not to the solution their state has proposed. Readers Forum: Op-Ed Contributors In June, North Dakota plans to open an outlet that will let Devils Lake water travel into the Sheyenne River and on into the Red River, which flows north into Canada. From there the water will eventually stream into Lake Winnipeg and the Hudson Bay watershed. Devils Lake, a remnant of a shallow glacial sea, is a closed ecological system that has been geographically separate from the surrounding Hudson Bay basin for more than a thousand years. Its salty waters have high concentrations of nitrogen, sulfates and phosphates - minerals that could cause severe digestive distress if consumed and could be lethal to aquatic life. Because of these contaminants, North Dakota does not allow Devils Lake waters to be used for irrigation. Once the canal is opened, the pollutants will enter the water supply of downstream communities in North Dakota, Minnesota and Manitoba. Moreover, species of fish, plants, parasites and viruses previously confined in Devils Lake, in some cases for millenniums, will spill out into the Sheyenne and Red Rivers. There they could kill the native plants and fish of the larger ecosystem. The consequences for Lake Winnipeg, the largest freshwater fishery in North America, are particularly worrisome. Despite concerns on both sides of the border about maintaining safe water sources, North Dakota has decided to pump out Devils Lake water without undertaking any environmental assessment or establishing ecological safeguards. There is a solution to this impending crisis. Nearly 100 years ago, Canada and the United States established the Boundary Waters Treaty. Under that treaty the two governments set up an International Joint Commission to address differences of opinion involving boundary waters. So far, of the 53 issues the two countries have jointly referred to the commission, 51 have been resolved by mutual agreement. For over a year, Canada has been requesting that North Dakota put off pumping water while the United States and Canada refer the issue to the commission for a time-limited, independent, scientific review. Both the Canadian and Manitoban governments have stated that they will support the commission's finding, whatever it may be. The governors of Minnesota and Missouri, as well as many other officials, have expressed support for the Canadian request in letters to the United States secretary of state. At their March meeting in Waco, Tex., President Bush, Prime Minister Paul Martin of Canada and President Vicente Fox of Mexico pledged to enhance water quality "by working bilaterally, trilaterally and through existing regional bodies." Secretary of State Condoleezza Rice should demonstrate the strength of that commitment by joining Canada in referring the Devils Lake project to the joint commission. If instead the Devils Lake project goes forward without a review, it will damage not only the region's environment and economy, but also North America's most important bilateral water management arrangement. There is a better solution. Frank McKenna is the Canadian ambassador to the United States. |

| 4/20/2005 | $26 million targets Salton Sea restoration projects | |
| Contacts | $26 million targets Salton Sea restoration projects By REBECCA ADAMUS, Special to Imperial Valley Press WASHINGTON (MNS) —Congress' ears are perking up to the cry of the Salton Sea, which is beset by a host of environmental problems that must be addressed sooner rather than later, local authorities and lawmakers say. The Senate Environment and Public Works Committee reauthorized $1.1 billion in funding Wednesday for water projects throughout California. Included in the package was $26 million to Imperial County for Salton Sea restoration projects. "These are actual pilot projects that are going to be moving forward that we hope will get funding and will start the process," said David Sandretti, a spokesman for Sen. Barbara Boxer, D-Calif., who sits on the committee. "This is a massive environmental disaster on our hands that is going to take a huge commitment of both federal and local resources." Sandretti said he expects the bill to go to the Senate floor sometime in June. Provided it is actually appropriated, the money would be distributed to the Salton Sea Authority, he added. Federal funding amounts to $16.9 million, and the Salton Sea Authority will have to match the federal funds with $9.1 million. No project may exceed $5 million. Odor control, salt evaporation and wetlands construction are some of the restoration projects likely to be funded under a final bill. Numerous federal and state studies have been conducted over the years to determine the types of projects that would best work for the sea. But the time for studies is over, according to Brian Nestande, a Salton Sea Authority consultant. "We don't want to do any more studies," he said. "Our board is still making technical changes and coming up with the final solution," but by the time the bill passes later this year, the authority will be ready to construct a project, he said. The language of the Salton Sea section of the bill, however, calls for yet another study. It says "a special study" must determine that all projects meet environmental and economic conditions of the Salton Sea Reclamation Act of 1998. Rather than sending the results of that study back to Congress for more authorization — often standard operating procedure, according to Sandretti — the section also says the Salton Sea Authority will be allowed to move forward with implementing projects. "The extra language helps speed this along," Sandretti said. Although "$26 million is fantastic," it's too early to get excited, Nestande said. He will wait and see what happens as the bill moves through full committee and the Senate, he added. |

| 3/4/2005 | U.S. Allows Trade in Caviar of Threatened Beluga Sturgeon | |
| Contacts | WASHINGTON, DC, March 4, 2005 (ENS) - A special rule to exempt trade in meat and caviar from threatened beluga sturgeon from permits normally required under the Endangered Species Act was issued Thursday by the U. S. Fish and Wildlife Service. Currently, eight coastal countries with indigenous beluga populations allow the commercial harvest and export of beluga sturgeon: Azerbaijan, Bulgaria, the Islamic Republic of Iran, Kazakhstan, Romania, the Russian Federation, Serbia and Montenegro, and Turkmenistan. "We believe this special rule provides great incentives to countries harvesting beluga sturgeon to work with the U.S. to restore and conserve wild populations," said Service Director Steve Williams. "The rule is also an effective tool to encourage aquaculture facilities to get involved in the recovery of these economically valuable fish." Environmentalists and marine scientists criticized the new policy which applies to international, foreign and interstate commerce. They cited evidence of the sturgeon's decline in recent years, and said the exemption could mean extinction of the most valuable fish in the world. Caviar Emptor - a coalition of SeaWeb, Natural Resources Defense Council and the University of Miami’s Pew Institute for Ocean Science - said it had expected the Service to restrict or ban beluga caviar imports after the agency placed beluga sturgeon on the threatened species list last year. The ruling comes after a four year struggle by conservationists to reverse the decline of the beluga, whose population in the Caspian Sea has plummeted by 90 percent in the past two decades due to overfishing, pollution, habitat loss and lack of effective governmental management. Caviar Emptor has been urging protection for the fish since it petitioned the government in December 2000 to list the fish as endangered under the U.S. Endangered Species Act. “Science shows that the best chance for recovery would have been to give beluga sturgeon a complete break. Today’s decision falls short of that,” said Dr. Ellen Pikitch, professor and director of the University of Miami’s Pew Institute for Ocean Science. “The candle is burning on both ends for the species, with surveys showing fewer and fewer young fish entering the population and many adults killed for their caviar before having a chance to reproduce." The eight countries must submit written management plans, annual reports and copies of national fishing laws on a specified schedule to the Service in order to use this exemption. If an exporting country fails to meet that schedule, then U.S. importers would have to comply with all the Act's permitting requirements for threatened species. The sturgeon range countries have six months from today to submit their beluga sturgeon conservation and management plans to the Service for review. Williams said that during this time, imports, re-exports, and interstate commerce of certain beluga sturgeon products will not require threatened species permits, but still must be accompanied by permits issued under the Convention on International Trade in Endangered Species (CITES), a global agreement that monitors and controls trade in fish, wildlife and plants through a system of permits. Lisa Speer, senior policy analyst for the Natural Resources Defense Council, said, “We are extremely disappointed that the beluga caviar trade was not banned. This decision does not go far enough to provide beluga sturgeon with the protection it needs, especially given that the U.S. is the world’s largest importer of beluga caviar.” “It is in the hands of consumers to help save this species,” said Dawn Martin, executive director of SeaWeb. “It doesn’t make sense to eat the eggs of a threatened species such as beluga sturgeon. There are a number of exquisite American caviars in which we can indulge with pure enjoyment and without guilt.” |

| 2/28/2005 | Great Salt Lake Mercury Worries Scientists - February 22, 2005 — By Associated Press | |
| Contacts | SALT LAKE CITY — Federal scientists studying the Great Salt Lake have found some of the highest levels of mercury ever measured anywhere -- prompting concern about some of the migratory birds that feed on the lake's brine shrimp. U.S. Geological Survey and Fish and Wildlife Service researchers were initially gathering information on selenium in the lake, but decided also to test the samples for mercury. Concentrations of methylmercury -- the element's most poisonous form -- exceeded 25 nanograms per liter of water. Fish consumption warnings have been issued when there was just 1 nanogram per liter. "We thought we would find some high levels of methylmercury," said David Naftz, the USGS research hydrologist who is heading the Great Salt Lake project, "but not some of the highest (the USGS) has ever found." There are no fish in the Great Salt Lake, and no evidence yet that mercury from the lake is getting into the human food chain. But the brine shrimp the project scientists have studied show evidence of mercury buildup that could be harmful to the lake's migratory birds. The bird they studied is the eared grebe, which eats brine shrimp from May to December. The researchers found mercury levels in the birds' livers more than doubled during their months on the lake. The study's preliminary findings eventually may overturn the long-held idea that areas of the lake's deep brine layer, which has no oxygen, is a kind of disposal system where toxins sink to the lake bed and become inert. Instead, the USGS study suggests the lake's peculiar chemistry actually speeds the conversion of mercury to its more toxic organic form. "It's not a disposal, it's a factory," Naftz said. Mercury is a highly toxic element that occurs naturally in the environment but also has been introduced through mining and industrial activity. Though the USGS studies have not found any evidence that mercury in the Great Salt Lake has entered the human food chain, ducks and geese that feed in the lake's wetlands could be subject to the same accumulation found in the eared grebes, said Fish and Wildlife researcher Bruce Waddell. People who eat the waterfowl might be exposed to mercury, agreed Steven Schwarzbach, a research manager for the USGS at the Western Ecological Research Center in Sacramento, Calif. The Great Salt Lake study hasn't yet tested that possibility, however. "There are some mysteries out here that are just starting to be discovered, so it's not fair to make an assessment of what's happening," Waddell said. Source: Associated Press |

| 2/2/2005 | SALTON SEA SYMPOSIUM ANNOUNCEMENT, CALL FOR TITLES AND REGISTRATION | |
| Contacts | www.isslr.org/userhtm/Salton_Sea_2005_REG_FORM.pdf | A Salton Sea for the 21st Century: Science, Rehabilitation, and Management A symposium to be held March 30 (8:30 am) - April 1 (12 noon), 2005 at the Hilton San Diego Mission Valley, 901 Camino Del Rio South, San Diego, CA 92108. Sponsored by the USGS Salton Sea Science Office, SDSU Center for Inland Waters, California Department of Water Resources, and the Water Education Foundation. This will be a multidisciplinary, multi-format, 2-1/2 day symposium with presentations and discussion on all aspects of the Salton Sea and its future. Most presentations will be by scientists and engineers but will be designed to be of interest to a broad audience. Since the second Salton Sea Symposium in 2000, there have been many new scientific discoveries about this lake many new ideas put forward on how to engineer its rehabilitation. The latest information on the dynamic ecology of the Salton Sea, its importance to people and wildlife, and its critical problems and their potential solutions will be presented. Speakers will be allowed, indeed encouraged, to make a poster presentation as well as an oral one. Presenters are requested to give close attention to two matters: 1) making their talks crystal clear to an audience of people with diverse specialties and interests, and 2) emphasizing, to the extent, possible the implications of their findings for understanding the future of the Salton Sea and for rehabilitation and management options. For scientists, this is your opportunity to directly address the relevance of your research findings to future management decisions. To the extent that the program allows, speakers may make a presentation on more than one topic. In some cases these might have to be combined into a single oral presentation, but two or more manuscripts would still be acceptable from such presenters. Manuscripts will have to be submitted within 30 days after the symposium; instructions for them and for abstract submissions will be provided to authors in a couple of weeks. Persons interested in making a presentation at the symposium should immediately send the title and authors to Jean Nordmann (jnordmann@watereducation.org) at the Water Education Foundation, for purposes of planning the program. These can be modified, if desired, at the time of abstract submission. The scientific papers presented at the symposium will undergo peer review, revision, and be published as a hardcover volume in the Developments in Hydrobiology series published by Springer. Stuart Hurlbert (shurlbert@sunstroke.sdsu.edu) and Doug Barnum (doug_barnum@usgs.gov) will serve as editors. Questions concerning the scientific program, abstracts, and publication should be directed to them. There also will be opportunties for exhibitors - vendors of commercial products, NGOs, government agencies - who might like to have a booth at the symposium. Cost of a booth for two days (March 30-31) will be $150 for NGOs and $500 for vendors, government agencies, and others. Sponsorships of various symposia events are available. Organizations or persons requiring additional information should contact the Water Education Foundation 916-444-6240. We apologize for duplicate postings as we revise our mailing distribution list. Please feel free to distribute this message to any colleague,organization or interested party. Register early for the best deal on hotel and registration costs. Registration form is attached. Hotel phone is 619-682-3947; special room rate for Symposium attendees is $119. |

| 1/19/2005 | Pilot project funded for selenium removal at Salton Sea | |
| Contacts | www.saltonsea.water.ca.gov | California Resources Agency awards $750,000 to the Salton Sea Authority for a pilot selenium removal project. The project is part of the Resources Agency's Salton Sea ecosystem restoration study. "The state is strongly committed to restoring the Salton Sea ecosystem and the permanent protection of the fish and wildlife dependent on that ecosystem," said the Resources Agency Secretary, Chrisman. "Today's action to provide additional financial support for the Salton Sea Authority's selenium removal pilot testing is another important step to preserve this valuable resource for future generations." The announcement was made during a meeting of the Resources Secretary's Salton Sea Advisory Committee. The Committee provides assistance and consultation to the Resources Agency, which is required by state law to prepare the Salton Sea ecosystem restoration plan by the end of 2006. The Salton Sea is an inland saline lake in southeastern California. The state's largest lake, it spans across Riverside and Imperial counties. It is a terminal lake, meaning it has no outlets. |
