Conewago River Conservation Plan

The Conewago Creek drains 510 square miles of steep mountain terrain, broad agricultural valleys, lush deciduous and coniferous forests, and several growing communities. As one of the largest subwatersheds within the Lower Susquehanna River drainage, the Conewago Creek has potential to greatly affect the condition of the Chesapeake Bay.

A River Conservation Plan is (according to PA DCNR):

" A comprehensive watershed or river-corridor based study. This study requires an inventory of existing natural, recreational and cultural resources, analysis of the issues, concerns, and threats to watershed resources and values, and actions leading to the development of a long-term watershed management program."

PEC partnered with the Watershed Alliance of Adams County (WAAC) and the Watershed Alliance of York (WAY) to complete the project. Other project sponsors include the Adams County Planning Commission, the Adams County Conservation District, the York County Planning Commission, and the York County Conservation District.

Steps to completing the Conewago RCP:

  • Formation of a project committee consisting of concerned citizens, agency personnel, local government officials/representatives, and other stakeholders
  • Extension public involvement program is constructed to garner citizen input, including public meetings
  • Key interviews with agencies, individuals and experts conducted.
