This project, on Cooks Creek in Durham Township, was the chapter’s first stream bank restoration project; 250 feet of eroding bank was restored.  Before restoration began the project site was approximately a 6 foot vertical bank that was rapidly eroding and contributing a large amount of sediment to Cooks Creek.  Sediment is detrimental to stream health in a number of ways; it fills areas of clean gravel where spawning trout deposit their eggs and where many species of mayflies, stoneflies and caddisflies live.

The restoration of this site involved grading the bank from vertical to a more gradual slope and installing two rock vanes to deflect high flows away from the bank.  Chapter members then installed erosion control fabric on the graded bank and then planted the area with native willow and dogwood species.

The rock vanes not only protect the bank from erosion but also have the added benefit of scouring a downstream pool, creating habitat for trout.  The willows and dogwoods were planted in the form of “live stakes” and “willow posts”.  As they grow their roots stabilize the bank and they also shade the stream and reduce the water temperature.  They also create habitat for insects, birds and other wildlife.

This grant also providing funding for the Heritage Conservancy to work on land preservation efforts in the Cooks Creek watershed as part of their “Lasting Landscapes” program.  Also, a list of prioritized land parcels was produced that the chapter is using to guide further restoration efforts.
