Watersheds
As defined by the EPA, a watershed is the land area that drains to one stream, lake or river. Watersheds exist at different geographic scales, from very large watersheds such as the land area that eventually drains to the Mississippi River, to the relatively small land area that drains to a local stream or pond. The health of a watershed directly affects the water quality of the body of water that it drains to. Because of this connection, healthy wetlands are an integral component of healthy watersheds, providing many essential ecosystem services.
Efforts to protect, restore, enhance and create wetlands improve overall watershed health and support climate change adaptation. Both traditional and innovative wetland protection and restoration projects - including hybrid systems using green infrastructure – are increasingly being employed to provide critical ecosystem services and benefits, such as increased flood and drought protection, clean drinking water, and habitat.
In 2019, ASWM completed a two-year project, entitled Healthy Wetlands, Healthy Watersheds, to help states and tribes build their capacity around integration efforts that leverage state wetland restoration and protection programs to improve watershed health. The products of this project include a white paper which can be found on our publication page, and state program integration case studies, watershed project integration case studies, and other support resources which are listed below.

Healthy Wetlands, Healthy Watersheds Worksheet for Integration Partners
Based on findings from ASWM’s Healthy Wetlands, Healthy Watersheds Project, this worksheet facilitates dialogue between partners as they conduct internal assessment of integration readiness. Partners should work together to review and discuss their levels of agreement with each statement and use the remainder of the worksheet to guide planning efforts. This worksheet is designed to supplement other capacity building resources and guides.
