Watershed and storm water management, also known as water resource management or total water quality management, is an approach to water quality improvements that focuses on the broad watershed level rather than individual water resources, such as river segments or wetlands. A watershed is a region that shares a common outlet for water drainage. Originally spurred by Vice President Al Gore's 1998 Clean Water Action Plan, it is driven by the Clean Water Act (CWA), Safe Drinking Water Act (SDWA), Coastal Zone Management Act, and Estuaries and Clean Waters Act of 2000. Watershed and storm water management encompasses areas such as water quality and source water protection standards.
