Nutrient Erosion Study Begins at California’s Clear Lake

Clear Lake, the largest natural lake entirely within California, has a severe problem with harmful algal blooms which can be detrimental to aquatic life by depriving it of oxygen when the algae dies, sinks, and decays. A driving factor of these conditions are the nutrient loads being carried into the lake by soil erosion and the transport of sediment from the lake’s tributaries.

Scientists Study Selenium Hazard in the Salton Sea Environment

In the past decade, Salton Sea water elevation has declined due to drought, lining of canals, and changes to management of the Colorado River. This has resulted in the creation of new wetlands caused by drains and rivers no longer reaching the Salton Sea.
