Activities of the Water Resources Division, California District, in the 1987 fiscal year
The mission of the Water Resources Division is to provide the hydrologic information and understanding needed for the optimum utilization and management of the Nation 's water resources for the overall benefit of the people of the United States. Several of the most relevant and visible studies being conducted by the California District deal with selenium toxicity in the western San Joaquin Valley; groundwater export from the Owens Valley, coupled with vegetation survivability studies; hydrodynamics variability in San Francisco Bay; reclaimed water use; seawater intrusion in the Santa Barbara area; and involvement in the water-quality standard/water-rights hearing for the San Francisco Bay/Delta. Thirty-nine project summaries are provided. Water Resources Division basic mission and program, California District organization and funding, and 1987 water conditions are also summarized.

Activities of the Water Resources Division, California District, in the 1986 fiscal year
This report summarizes the progress of water resources studies in California by the U.S. Geological Survey during the fiscal yr 1986. Much of the work was done in cooperation with State and local agencies. Additional supporting funds were transferred from other Federal agencies or appropriated directly to the Geological Survey. The water resources program in California consisted of 42 projects. Each project is briefly described. Brief descriptions are given of the origin of the U.S. Geological Survey and the Water Resources Division 's basic mission. An abbreviated organizational structure of the California District, sources of funding, a summary of water conditions, and a listing of reports published during fiscal year 1986 are also included.

Ground-water conditions and well yields in fractured rocks, southwestern Nevada County, California
This report describes the availability of ground water in the southwestern part of Nevada County, and suggests general guidelines for selecting sites for future ground-water development in the study area. Ground water in this area occurs chiefly in fractures in hard pre-Tertiary metavolcanic and plutonic rocks generally above a depth of 215 feet. Some ground water is found at the contact between alluvium or decomposed granite and the underlying hard rock; little is found in alluvium or colluvium. Mean yield is less than 18 gallons per minute.
