Snow and Water Interactive Map

The Snow and Water Interactive Map displays both current and historic hydrometeorological data in an easy-to-use, visual interface. The information on the map comes from many sources. Natural Resources Conservation Service snowpack and precipitation data are derived from manually-collected snow courses and automated Snow Telemetry (SNOTEL) and Soil Climate Analysis Network (SCAN) stations. Other data sources include precipitation, streamflow, and reservoir data from the U.S. Bureau of Reclamation (BoR), the Applied Climate Information System (ACIS), the U.S. Geological Survey (USGS), and other hydrometeorological monitoring entities.

The Interactive Map has two regions: the map display (on the left) and the map controls (on the right). You use the map controls to determine both the display mode and the types of data and stations to show on the map.

Predefined Maps: Station and/or Basin Conditions

To help you get started with the Interactive Map, here are links to predefined maps organized by data type. After opening a map, you can zoom to your area of interest, customize the map, and then bookmark the URL to save your settings. Show current conditions for stations, basins or both.
