This Lake Tahoe Data Clearinghouse website, created and maintained by the footer image. U.S. Geological Survey (USGS) in partnership with Federal, State, tribal, and local agencies and groups, is a gateway to information and data on Lake Tahoe and its basin.
This data layer consists of the USGS Surface Water Gage Stations that are located within the study area of the Truckee River Information Gateway (TRIG). The coordinates are taken directly from the USGS station information webpage. The data collected from these gages is used in the sources and loadings analyses component of the TRIG project.
This data is a subset of the United States Geological Survey (USGS) watershed data layer, consisting of the Truckee river Watershed, delineated by Hydrologic Unit Code (HUC). This watershed boundary defines the original study boundary of the TRIG program and associated analyses.
In 1889, the U.S. Geological Survey established its first gaging station in Nevada and providing to the public data about Nevada's water resources. Today, this systematic collection and dissemination of hydrologic data is made possible with the cooperation from Federal, Tribal, State, and local agencies. A list of our current cooperators is available online.
These pages provide access to water-resources data collected at approximately 20,000 sites in Nevada. Online access to this data is organized around the categories listed to the left.
The USGS investigates the occurrence, quantity, quality, distribution, and movement of surface and underground waters and disseminates the data to the public; Tribal, State and local governments; public and private utilities; and other Federal agencies involved with managing Nevada's water resources.
