Water Resources Data for California, Water Year 1987. Volume 2. Pacific Slope Basins from Arroyo Grande to Oregon State Line Except Central Valley

Abstract

PREFACEThis volume of the annual hydrologic data report of California is one of a series of annual reports that document hydrologic data gathered from the U.S. Geological Survey 1 s surface-and ground-water data-collection networks in each State, Puerto Rico, and the Trust Territories.These records of streamflow, ground-water levels, and quality of water provide the hydrologic information needed by State, local, and Federal agencies, and the private sector for developing and managing our Nation 1 s land and water resources. This report is the culmination of a concerted effort by dedicated personnel of the u.s. Geological Survey who collected, compiled, analyzed, verified, and organized the data. In addition to the authors, who had primary responsibility for assuring that the information contained herein is accurate, complete, and adheres to U.S. Geological Survey policy and established guidelines, the individuals contributing significantly to the collection, processing, and tabulation of the data are given on page V.This report was prepared in cooperation with the California Department of Water Resources and with other agencies, under the general supervision of John M. Klein, District Chief, California. III 'OZI"l•f 01REPORT DOCUMENTATION i 1. REPORT No. lz. Water resources data for the 1987 water year for California consist of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water. quality in wells. Volume 2 contains discharge records for 123 gaging stations; stage and contents for 7 lak~s and reservoirs; and water quality for 29 stations. Also included are 1 partial-record station and 24 water-quality partial-record stations, These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in California.

To make these data readily available to interested parties outside the U.S. Geological Survey, the data are published annually in this report series entitled "Water Resources Data-California."This volume of the report includes records on surface water in the State.Specifically, it contains (1) discharge records for 123 streamflow-gaging stations and 1 low-flow partial-record streamflow stations (2) stage and contents records for 7 lakes and reservoirs; and (3) water-quality records for 29 streamflow-gaging stations. Records included for stream stages are only a small fraction of those obtained during the water year.The series of annual reports for California began with the 1961 water year with a report that contained only data relating to the quan...
