A beautiful 100-acre lake off the Susquehanna that feeds Exelon Power’s Muddy Run Pumped Storage Facility, generating electricity for the surrounding area during peak demand periods. This park has a wide variety of offerings including great birding, a disc golf course, picnic areas, playgrounds, boat launches for water access, hiking trails, and an observatory. It is pretty far south in the county, but it is definitely worth the trip.
