The Carson River Basin Hydro Mapper web application provides a modern and easy-to-use interface with the USGS National Water Information System (NWIS). It is also a one-stop location for visually descriptive summaries of USGS, SNOTEL, National Weather Service, Advanced Hydrologic Prediction Service, and other local and regional hydrologic data with access

Integrated model boundaries used in evaluating the effects of groundwater management options on water resources in the Carson Valley, Douglas County, NV.

Since the late 1980’s, USGS has collected discharge, sediment, and water quality data at seven major drainages as part of the Lake Tahoe Interagency Monitoring Program (LTIMP). Continuous, real-time measurements of turbidity recently were added to LTIMP sites. Similarly, the U.S.

The graph shows historic pumping over time in Carson Valley, NV. Between the 1970s and early 2000’s, Carson Valley underwent rapid population growth and total pumping increased by an order of magnitude, from 3,360 acre-feet in 1970 to 31,100 in 2004.

Did you know the USGS has been studying groundwater since we were founded? USGS first measured the groundwater level at the well in this photo in 1918, over one hundred years ago! How often water levels are measured at a site in the USGS groundwater monitoring networks varies, depending on the scientific purpose of the measurement.
