Water is one of six science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources. This database contains downloadable water-related spatial data files for exploration and analysis.
The Columbia River Basin provides habitat for salmon and steelhead, essential components of a healthy ecosystem and critical to Indian tribes and local communities. Loss of quality habitat because of pressures from population growth threaten fish numbers and the overall health of the basin. With this Critical Conservation Area designation, USDA will build on existing strong partnerships in the basin to work with agricultural producers to improve water quality and quantity in order to restore critical components of salmon habitat, aid in the recovery of Pacific salmon, and protect public health and the environment while maintaining a strong agricultural sector. The boundary of the CCA is a portion of the Columbia River Basin that includes essential fish habitat. This dataset includes a printer-friendly CCA map and shapefiles for GIS.
Irrigated agriculture is vitally important to the economy and quality of life in many areas of the Colorado River Basin. It also accounts for a significant share of the basin’s existing water use, shared among 33 million people in the United States plus 3 million in Mexico. Faced with historic drought conditions and water supply pressures, farmers, ranchers, Indian tribes and other water users are in urgent need of accelerated conservation on working agricultural lands. This dataset includes a printer-friendly CCA map and shapefiles for GIS.
The Mississippi River is North America’s largest river, flowing over 2,300 miles through America’s heartland to the Gulf of Mexico. The watershed not only provides drinking water, food, industry, and recreation for millions of people, it also hosts a globally significant migratory flyway and home for over 325 bird species. This dataset includes a printer-friendly CCA map and shapefiles for GIS.
The NRCS National Water and Climate Center's 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…
The Watershed Boundary Dataset (WBD) from The National Map (TNM) defines the perimeter of drainage areas formed by the terrain and other landscape characteristics.
