Overview
Lake Arthur is a roughly 3,225-acre reservoir on Muddy Creek in Butler County, the centerpiece of Moraine State Park in western Pennsylvania. The lake and park are managed by the Pennsylvania Department of Conservation and Natural Resources as a major public recreation resource about 45 minutes north of Pittsburgh. Unlike many Corps flood-control lakes, Arthur was built primarily as a state park reservoir for outdoor recreation.
