The Watershed Health Assessment Framework (WHAF) mapping application was developed to support natural resource management through an approach that emphasizes ecosystem health.

The WHAF application delivers a suite of watershed health index scores, each index represents a unique facet of the ecosystem. The index scores are organized within the five components of ecosystem Health: Hydrology, Geomorphology, Biology, Connectivity, and Water Quality. This 5-Component model provides a consistent structure for delivering a balanced and repeatable exploration of watershed conditions.

In addition to health scores, the application provides access to:
- Watershed boundaries with tools to visualize patterns of water movement.
- 100+ GIS data layers that provide insights to support natural resource management decisions and planning efforts.
- The ability to chart land cover at each watershed scale.
- The ability to save and share interactive map layouts through custom links and bookmarks.

The WHAF application is accessible from any modern web browser, although we recommend using a recent version of Google Chrome or Mozilla Firefox.

The WHAF health scores are also available for use in desktop GIS software, the data can be downloaded from Watershed Health Assessment Scores.

Data delivered through the application varies in origin and date of publication. Every effort is made to use the most current data available, and keep resources in sync with updates made to the source data. For detailed information regarding the data used to derive health scores, consult the health score analysis documentation. For detailed information regarding the source and publication data of additional GIS layers, consult the GIS Data Sources list.

When a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area is designated as “critical habitat” after the Service publishes a proposed Federal regulation in the Federal Register and receives and considers public comments on the proposal. The final boundaries of the critical habitat are also published in the Federal Register. Critical habitat are areas considered essential for the conservation of a listed species. Federal agencies are required to consult with the U.S. Fish and Wildlife Service on actions they carry out, fund, or authorize to ensure that their actions will not destroy or adversely modify critical habitat. These areas provide notice to the public and land managers of the importance of these areas to the conservation of a listed species. Special protections and/or restrictions are possible in areas where Federal funding, permits, licenses, authorizations, or actions occur or are required.Note: The linear critical habitat layers were officially deprecated on 06/05/2025. All previously linear critical habitat has been converted to polygons are included in the layers below.
