There has been a recent surge in interest in recreation at the Salton Sea, including the upcoming SEAthletes SEATalk and North Shore Xtreme recreation event, aimed at bringing more public attention to the Sea. However, this is only one chapter in a long history of public recreation at the Salton Sea. Continue reading “Fun in the Salton Sun”
Several previous posts have discussed the ecological importance of the Salton Sea, particularly its effect on migratory birds. However, the Salton Sea is also home to a much less obvious endangered species, the tiny desert pupfish. Desert pupfish, which are less than 3” long fully grown, are an unusual species due to their incredible tolerance for extreme water conditions. The desert pupfish can survive at salinities of up to 70 g/L—more than double the salt concentration of seawater. This has historically allowed the desert pupfish to live in saline lakes, rivers, and marshes throughout the deserts of California, Arizona, Colorado, Nevada, and Mexico.
Several months ago, the Torres Martinez tribe announced that they will be growing medical marijuana on tribal lands in the near future. The income from this growing operation could provide the Torres Martinez tribe, and the surrounding area, with a much needed economic boost. However, large-scale growing of the water-intensive marijuana plant may pose an environmental risk in an area already gripped by drought.
Many of the predictions and concerns about the future of the Salton Sea are based on historical examples of other salt lakes around the world, and their impacts on local communities—some beneficial, and some disastrous. Three examples of highly saline terminal lakes, the Aral Sea, Owens Lake, and the Great Salt Lake, show some of the possible outcomes for the Salton Sea.
The drying of the Aral Sea has intense negative effects on communities in Kazakhstan and Uzbekistan in terms of local economies, environments, and health. As the sea dried, dust storms and soil loss resulted in desertification of croplands and contamination of surface fresh water.  The shoreline retreated by miles, crippling the local economy, which was dependent on fishing and transportation. Due to extensive pesticide usage in the area, the dust from the Aral Sea contains DDT, PCBs, dioxins, and heavy metals, which have been found at high levels in pregnant and nursing women in Kazakhstan and Karakalpakstan.  Public health studies in the area have found widespread thyroid abnormalities, as well as lung malformations in children.
