WatershedOverview

The term watershed refers to the geographic boundaries of a particular waterbody, its ecosystem and the land that drains to it. A watershed also includes groundwater aquifers that discharge to and receive discharge from streams, wetlands, ponds, and lakes. Large watersheds are sometimes referred to as river basins.

Relevant Activities

Role of Local Governments

Watershed protection/restoration is accomplished through efforts at various levels including EPA, state agencies, local agencies, and private organizations. In most cases watersheds do not conform to political boundaries and, therefore, effective solutions require cooperative efforts. 

States are required, under the Clean Water Act, to develop lists of impaired waters. Impaired waters are those that are too polluted to meet specified water quality standards. The law requires that states establish priority rankings for waters on the lists and develop total maximum daily loads (TMDLs) for these waters. A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards.

The EPA has encouraged states and others to develop watershed plans to help protect and restore our waters. Watershed planning helps address water quality problems in a holistic manner by assessing the potential contributing causes and sources of pollution, then prioritizing restoration and protection strategies to address these problems. A watershed plan provides an analytical framework for managing efforts to restore water quality in degraded areas and protect overall watershed health. Many communities across the country struggle to find the right approaches, tools, and data to include in their watershed plans. The complexity and diffuse nature of pollution, the costs of restoration and remediation, and the need to achieve voluntary action by individual landowners can require years of support from a coalition of stakeholders, programs, and funding sources.

Funding & Financing

The Clean Water State Revolving Fund (CWSRF) can be utilized in ways that encourage watershed protection.
