Nonetheless, hydrologic units and watersheds are commonly treated as synonymous, and this misapplication and misunderstanding can have some serious scientific and management consequences." [ 9 ] Aquifers of the United States are organized by national principal aquifer codes and names assigned by the National Water Information System (NWIS).
Watershed management, the management of drainage basins; Watershed Protection and Flood Prevention Act, a United States law controlling drainage and water storage; Watershed district (Minnesota), one of a number of government entities in the US state of Minnesota which monitor and regulate the use of water in drainage basins
The list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies.

[6] However, Granholm's Executive Order No. 2009-45 combined the two over the objections of the Senate. [3]
Using digital elevation models combined with peak discharge data can predict which areas of a floodplain will be submerged depending on the amount of rainfall. In a study of the Illinois River watershed, Rabie (2014) [6] found that a decently accurate flood risk map could be generated using only DEMs and stream gauge data. Analysis based on ...
Watershed districts are special government entities in the U.S. state of Minnesota that monitor and regulate the use of water in watersheds surrounding various lakes and rivers in the state. The districts cover the natural regions of the watersheds, rather than politically defined regions and thus may have boundaries that cross jurisdictions.
The Iowa Department of Natural Resources (Iowa DNR or IA DNR) is a department/agency of the U.S. state of Iowa formed in 1986, charged with maintaining state parks and forests, protecting the environment of Iowa, and managing energy, fish, wildlife, land resources, and water resources of Iowa.
A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units as part of the U.S. hydrologic unit system.
