Wissahickon Clean Water Partnership

The communities of the Wissahickon Watershed have a momentous opportunity to Own the Solution and create their own Total Maximum Daily Load - a regulation that limits the amount of pollutants that the creek can handle while still meeting water quality standards. Municipalities of the watershed would collaborate to share resources, costs, and support to create this plan over the next two years. Together, we can mitigate damaging floods, protect fish and wildlife, prevent further streambank erosion, and return valuable recreation areas.
