Hydrogeology of Lake Tahoe Basin, California and Nevada, and Results of a Ground-Water Quality Monitoring Network, Water Years 1990-92

摘要

The purpose of the study was to design and operate a network to monitor thequality of ground water that ultimately discharges to Lake Tahoe. The long-range goal of the study is to provide information to decisionmakers about the relative significance of ground water to the nutrient budget of the lake. The purpose of this report is to describe and document the design of the network and to present interpretations of the results obtained during its implementation in 1990-92. Historical data are summarized to describe the hydrogeologic and geochemical settings. The network is evaluated in terms of how effectively the results characterize the quality of ground water that may interact with Lake Tahoe, and how effective continued network operation may be at addressing water-quality objectives of the regional planning agency.
