History of the Perkiomen Watershed Conservancy

Nature formed the Perkiomen watershed, a geographic unit of land complete with its own drainage system of surface streams. For centuries the watershed welcomed its human inhabitants, tolerated our changes in lifestyle and the industrial and commercial development associated with the changes. However, danger signs in the form of destructive storms, too much rainfall, or too little, are sent from time to time as reminders of who is really boss over individual ownership and municipal boundaries.

A stop sign in the form of a record drought (1962-1966) warned an increased population that we were stressing the soil-related and water resources of the watershed. Groundwater levels lowered. Some streams went dry. What remained of the surface water system could not assimilate and carry away an overload of agricultural, industrial and community pollutants.

The Perkiomen Watershed Conservancy (PWC), originally the Perkiomen Valley Watershed Association, was organized in 1964 to help address these poor water conditions in the Perkiomen Creek watershed. Early involvement was divided between public education activities, continuing data collection, efforts to advance the idea of state water quality standards and a required degree of treatment for wastes discharged to streams.

In the 50 years since those first meetings, the PWC has helped clean up tons of trash from area creeks, has helped in the preservation of Spring Mountain, has helped educate thousands of children and adults about the natural world and our connection to nature and has helped preserve and repair riparian areas along local creeks to help reduce erosion and improve water quality.

Scioto Wetland Demonstration Project
Since 2008, engineering and planning has been conducted to construct this wetland behind Upper Frederick Township's Municipal Office. Before stormwater enters a tributary to the Scioto Creek, it will enter the wetland, where it will be filtered by 5000 native plants. This wetland will be home to much wildlife, including many mosquito eaters like frogs and dragonflies! A wooden split-rail fence was constructed around the wetlands perimeter to protect this habitat. Look for our kiosk at the site to gain more information about wetlands and their great impact on water quality.
