Water and Climate Information
This page contains data, reports and information related to water supply forecasts, reservoirs, and the Surface Water Supply
Index (SWSI). This information is provided to assist in forecasting the
water supply for the western United States.
The Snowpack page includes data and reports derived from snow survey sites
located in the western United States. Here you will find state and site
specific data, maps and graphs showing snow water equivalent, snow depth,
precipitation, temperature and other climatic elements in hourly, daily, monthly
and yearly increments. These products are used for forecasting and
management of water supplies.
The Snow Course page provides data and reports derived from snow course
sites located in the western United States.
The Soil Climate Analysis Network consists of automated remote sites which
collect soil moisture and soil temperature data along with precipitation, wind,
and solar radiation data. These sites are located throughout the United
States and other global locations. This data is used for the management
and prediction of climatic issues affecting our natural resources.
Climate products include information and data for Wetlands Determination,
Temperature and Precipitation Summaries, Frost Free Days, and Growing Seasons.
PRISM data and information, Narratives and Tables for Soil Survey Regions of the
United States, and Weather Generator Technology model (GEM) information can also
be found in this section.
The National Water and Climate Center is pleased to introduce a new suite of
maps displaying variables such as snow water equivalent, snow depth, snow
density, precipitation and temperature. Maps are generated at a variety of
scales for the western United States using SNOTEL, snow course, and ACIS
