Measure W Watersheds

Guidance on Reporting Watershed Improvement

EPA has prepared guidance to help “implement” this measure. The guidance defines the performance measure and key terms (e.g., improvement), and provides reporting format templates.

Please contact us if you have any questions, including if you have a watershed that you would like to track for this measure.

Measure “W” (also known as the Watershed Improvement Measure (WIM) and SP-12) is a key performance measure in EPA’s Strategic Plan. The measure tracks watersheds where water quality conditions have improved by utilizing a watershed approach. One of the primary purposes of this measure is to model and demonstrate the effectiveness of the watershed approach. EPA has a nation-wide goal to improve water quality conditions in 250 watersheds for 2012. EPA Region 9 and our state water quality agency partners have agreed to track the following watersheds for purposes of reporting on this measure and documenting environmental results, and to better focus our water quality restoration activities by identifying needs, sharing information, providing assistance and learning more about the related challenges. We expect some of these watersheds to show improvement by 2012 for the identified pollutant. Additional watersheds may be added and/or substituted.
