Ground-water levels in water year 1987 and estimated ground-water pumpage in water years 1986-87, Carson Valley, Douglas County, Nevada

Groundwater levels were measured at 58 wells during water year 1987 and a summary of estimated pumpage is given for water years 1986 and 1987 in Carson Valley, Douglas County, Nevada. The data were collected to provide a record of groundwater changes over the long-term and pumpage estimates that can be incorporated into an existing groundwater...

The use of total lake-surface area as an indicator of climatic change: Examples from the Lahontan basin

Variation in the size of lakes in the Lahontan basin is topographically constrained. River diversion also has played a major role in regulating lake size in Lahontan subbasins. The proper gage of lake response to change in the hydrologic balance is neither lake depth (level) nor lake volume but instead lake-surface area. Normalization of surface...

Groundwater pumping, which has been increasing since the 1940s, now accounts for about one third of the estimated annual flow from the aquifers of the eastern Great Basin. In parts of this region, groundwater pumping exceeds the rate of natural discharge, leading to land subsidence and declines in water levels and spring flow.
