Rapid Stream Delisting

350 miles streams restored by 2030

The Lancaster Clean Water Partners has a goal to restore 350 miles of impaired streams in Lancaster County by 2030. Nutrient and sediment pollution have made more than half of Lancaster’s 1,400 miles of streams unsafe for drinking, recreation, as well as critical insect and fish populations. But many partners throughout the county are working to rapidly restore these waterways using a new and innovative strategy called “rapid stream delisting.”

If successful, 350 miles of impaired streams will be removed from the impaired streams list by 2030. Additionally, nutrient and sediment pollution levels will have decreased enough for critter and fish populations to live and thrive in the stream again.

The delisting strategy was created by the Chesapeake Conservancy. It couples cutting-edge mapping data analysis with an extensive partnership effort to align limited resources toward delisting streams on an accelerated time frame. The Partners’ goal of 350 miles of Lancaster streams coincides with Pennsylvania’s goal of 30 streams restored by 2030.

On April 26, 2021, the Partners’ RCPP proposal was selected to receive $7.4 million to implement best management practices on agricultural lands, resulting in restored and healthy streams.
