The tributaries of these five watersheds run through some of the most productive fish and wildlife habitat in the Northern Chester County. The region is largely rural with more than 70% of the population who depend on the ground water for their drinking water. All of the watersheds under GVA’s stewardship are designated either “High Quality” or “Exceptional Value” by the Commonwealth of Pennsylvania. “Exceptional Value” is the highest protective designation offered by the Commonwealth.
