From introduction: In 1971, the U.S. Geological Survey (USGS) began a cooperative study to measure stream discharge, suspended-sediment load, and chemical quality of surface waters draining the project area. In 1976, the study was expanded to include measurement of ground-water levels and quality. The general hydrologic system in the vicinity has been described by Patterson, Fuentes, and Toler (1982)
