The Regional Conservation Partnership Program (RCPP) led by USDA's Natural Resources Conservation Service, was created by the 2014 Farm Bill to promote partnerships in conservation. Under the RCPP, more than 40 partners in Ohio, Michigan, and Indiana formed the Tri-State Western Lake Erie Basin (WLEB) Phosphorus Reduction Initiative.

The Tri-State RCPP consists of a diverse team of partners using a targeted approach to identify high-priority sub-watersheds for phosphorus reduction and implement conservation practices on the 855,000 acres that have been identified as the most critical areas to treat.
