Missouri Watershed Inventory and Assessment

This site has been established to provide natural resource-related information specific to Missouri's primary watersheds, especially information pertaining to the wise management of the aquatic resources. The state's watersheds are often indexed in one of two ways, either with the USGS 8-digit hydrologic unit listing or the primary watershed delineation used by the Missouri Department of Conservation. These two indexing methods differ slightly, but you will be able to find information on watersheds in the state by using either index. On this page you may select which ever index you are most comfortable with using.
