Cherry Creek is a pristine 15-mile coldwater fishery that flows through the narrow, steep-sided Cherry Valley in Monroe County, Pennsylvania, before emptying into the Delaware River at Delaware Water Gap. This second-order valley stream originates above Twin Ponds just east of Route 33 and south of Saylorsburg, with its flow substantially increased by large springs located downstream from the pond outflow and above the Cherry Valley Trout Hatchery. The creek maintains a relatively gentle gradient with only 370 feet of elevation change from source to mouth, meandering through a complex geological foundation of limestone, shale, and siltstone overlain with glacial deposits. This limestone influence gives Cherry Creek much higher pH, alkalinity, and total dissolved solids compared to most acidic Pocono area streams, creating optimal conditions for trout populations. The Pennsylvania Department of Environmental Protection has classified Cherry Creek as a High Quality Coldwater Fishery, and significant portions are now protected within the Cherry Valley National Wildlife Refuge.
