Abstract

During 1975 and 1976, a large number of water and sediment samples were collected from the Walker River Basin. Additional surface water samples were collected during 1980 and 1981. Data are given herein for chemical analyses of snowmelt, tributary, river, spring, well, lake, reservoir, lake sediment pore fluid, tufa, lake and river sediment samples. These data provide the basis for consideration of processes which govern the chemical evolution of large closed basin hydrologic systems in the Basin and Range Province of the Southwestern United States.

The Walker River Basin, a part of the Basin and Range Province, is located i~ west-central Nevada and adjacent areas of California (fig. 1). The 10,900 km basin is drained by the east and west forks of the Walker River and by numerous small ephemeral tributaries (fig. 2). The entire drainage area forms a closed basin with no external outlet. The purpose of this report is to make available all chemical data collected by us on the system since 1975. These data serve as a basis for future studies of the geochemical evolution of this system.
