“Recovery Potential” Recovery potential is the likelihood of an impaired
water to re-attain a desired condition, given its:
Ecological capacity
Exposure to stressors
Social context affecting efforts to improve its condition
Recovery Potential Screening Developed by U.S. EPA to provide states with a means
to compare restorability and make strategic decisions for:
TMDL development
TMDL implementation
Stream restoration
Targeting 319 grants and other funds
Monitoring for water quality improvements
Many more!

Project Scope Staff involvement from 319, 303(d), CZM, DER
Selection of indicators for each of three categories:
Watershed ecological condition
Watershed stressors
Social capacity for restoration
Indicators compiled/calculated at both the HUC12 watershed and the SWMI subwatershed scale
84 Indicators Calculated 24 ecological metrics
Number of confluences, watershed % forest, stream corridor % forest, etc.
45 stressor metrics
Watershed % urban, dam density, water use intensity, etc.
15 social metrics
Protected land percentage, presence of water-based recreation, number of public water supply intakes, etc.

Next Steps for Massachusetts Share with partners and convene a Recovery Roundtable to
encourage synergistic work: EOEEA MassDEP GIS, Wetlands, CAPS program, BWSC-NRD, DWM, DMS DFG/EER Riverways CZM
Potential Applications: Public outreach and education TMDL prioritization Assessment and monitoring decisions Healthy watersheds protection Selection of Farm Bill target watersheds Land acquisition decisions
