Nevada

Overview April 24, 2014

Nevada

As adjacent Western states, California and Nevada share similar issues related to drought and limited water resources. Both states are participants in the 1922 Colorado River Compact and the 2003 and 2007 Quantification Settlement Agreements to allocate Colorado River deliveries. Also, about two-thirds of Lake Tahoe lies in California and one-third in Nevada, and the two states have formed a compact to work together on environmental goals for the lake.

Pyramid Lake

Overview April 24, 2014

Pyramid Lake

Pyramid Lake in Nevada has long been a focal point in a tug-of-war between water stakeholders. There’s been a struggle for water in this arid land among the American Indians, farmers, cities, environmentalists and the people of Nevada and California. The lake is the site of the nation’s first reclamation project and the subsequent struggles among Nevada farmers, the Paiute Indian Tribe and the growing city of Reno over use of the lake’s water. In 1990 a settlement act attempted to resolve some of these competing uses.

Tulare Lake Basin

Overview April 24, 2014

Tulare Lake Basin

Until the early 1900s, central California’s Tulare Lake naturally appeared every winter as the southernmost rivers flowing out of the Sierra Nevada Mountains filled the dry lakebed with rainfall and melted snow.

Farmers adjacent to the lake also used the water to irrigate their lands. But the variable shoreline made growing seasons unpredictable. In response, Pine Flat Dam was built by the U.S. Army Corps of Engineers to control Kings River flows. The Kings River is still used extensively for irrigation.
