Lake Tahoe, CA/NV

March 31, 2003
Lake Tahoe, along the California-Nevada border, is one of the clearest lakes in the world. Since 1965 scientists have been monitoring the water’s clarity, and have discovered a 50% reduction in the last 35 years. This is attributed to increased algal growth, more sediment washed in from the surrounding areas, and urban growth and development. The ASTER image, on the left, was acquired November 7, 2000, and covers an area of 23 x 38 km.
