The Lancaster County Conservation District, in collaboration with many partnering organizations and agencies, has released the Lancaster County Watershed Report Card at https://lancasterconservation.org.

A watershed is an area of land in which all surface water drains to a common body of water and can be evaluated at multiple spatial scales. Lancaster County contains approximately 12 primary watersheds, which are further subdivided into smaller hydrologic units. Most of these watersheds ultimately drain into the Chesapeake Bay, underscoring the importance of monitoring local water quality and watershed health.

Many of Lancaster County's waterways are currently impaired by excess sediment and nutrients. To evaluate watershed conditions, a collaborative team of experts developed a Watershed Report Card to synthesize complex environmental data into accessible scores for stakeholders and the public. Sub-watersheds were assessed across six categories - Water Quality, Fish, Macroinvertebrates, Urban & Stormwater, Agriculture & Vegetation, and Riparian Zone - using multiple biological, chemical, and land-use parameters. Scores were classified from Very Poor to Excellent based on percentage thresholds.

Overall, Lancaster County sub-watersheds received an average rating of Fair, with Water Quality scoring lowest countywide and Fish and Urban & Stormwater scoring highest. Data was compiled from multiple partner organizations and agencies, with noted variability in data availability, watershed size, and designated stream uses.

This report card establishes a baseline for future assessments and supports Lancaster County's ongoing Delisting Strategy, which targets impaired waterways through focused conservation and restoration efforts. Updates to the report card will occur every five years to track progress toward water quality.
