"The 116th Congress may conduct oversight and deliberate on authorization and funding of water resource development, management, and protection. Congress engages in authorization and appropriations for water resource projects and activities of the U.S. Army Corps of Engineers (USACE) and the Bureau of Reclamation (Reclamation). USACE constructs projects nationwide, primarily to improve navigation, reduce flood damage, and restore aquatic ecosystems. Reclamation constructs projects in the 17 arid states west of the Mississippi River; these projects primarily provide water supply benefits, often to agricultural irrigation users. The 116th Congress, like earlier Congresses, also may consider Indian water rights settlements and may evaluate the focus of and funding for the water resource science activities of the U.S. Geological Survey (USGS)."
