A Reservoir Morphology Database for the Conterminous United States

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-21T00:00:00Z
In 2010, the U.S. Geological Survey (USGS), in cooperation with the U.S. Fish and Wildlife Service Reservoir Fisheries Habitat Partnership, combined multiple national reservoir databases into a Reservoir Morphology Database (RMD) for the conterminous United States. The RMD contains chemical, physical, and morphological metrics for 3,828 reservoirs that are greater than 250 acres in surface area. Methods of database construction and metric calculation are described in the USGS Data-Series Report published by Rodgers (2017).
