Lake Wallenpaupack

Lake Wallenpaupack in Wayne and Pike Counties of northeastern Pennsylvania occupies a special place in the Pocono Mountains region as one of the largest lakes in the state and a recreational hub that has served the area's resort culture for nearly a century. Created by Pennsylvania Power and Light in 1926 by damming Wallenpaupack Creek, the lake covers approximately 5,700 acres and stretches nearly 13 miles through the Pocono landscape of forested ridges and second-growth hardwoods that characterize this corner of the state. The lake's scale, its surrounding resort development, and its position within easy reach of the New York metropolitan area have made it one of the busiest recreational lakes in the Mid-Atlantic region. Freshwater diving at Wallenpaupack benefits from the lake's size, which allows divers to explore areas removed from the heaviest recreational boat traffic and find underwater conditions shaped by the lake's depth and the cleaner water quality of its more secluded arms and bays. The lake's maximum depth of over 50 feet provides a dive profile with both shallow training zones and mid-range depths appropriate for recreational diving, and the variable underwater topography—the original Wallenpaupack Creek valley preserved beneath the reservoir with its original ridges and creek channels—creates interesting terrain for systematic exploration. Visibility at Wallenpaupack follows seasonal patterns typical of northeastern Pennsylvania's forested lake districts. The surrounding Pocono forest provides a relatively clean watershed with limited agricultural nutrient input, contributing to water quality better than many agricultural-zone Pennsylvania lakes. Summer brings algal growth that reduces clarity, while spring and fall typically offer the clearest water. The lake's recreational popularity means boat traffic can stir sediment in shallow areas, though the deeper zones remain relatively protected from this type of disturbance. The biological community at Wallenpaupack reflects the cold-temperate freshwater ecosystem of northeastern Pennsylvania. Walleye—stocked by the Pennsylvania Fish and Boat Commission and naturally reproducing in the lake—are among the most prized encounters, their characteristic glassy eyes and preference for dim, deeper water making them a species that divers occasionally encounter in the lake's deeper zones. Largemouth and smallmouth bass occupy structure throughout the lake, while yellow perch form the open-water schools that provide the mid-water fish encounter experience typically absent from bass-dominated structure dives. Lake trout have been stocked historically and may persist in the lake's cold, deeper sections. The resort infrastructure surrounding Lake Wallenpaupack supports dive logistics in ways that wilderness lake access cannot—boat rentals, accommodation options, restaurants, and the general tourist infrastructure of the Pocono resort region are all accessible from the lake's shore. For diving couples or groups that include non-divers, this full-service recreational environment means that dive trips to Wallenpaupack can be combined with the other lake activities that make the Poconos a multi-generational destination. For dedicated diving visitors, the convenience of nearby services compensates for the crowd-management challenges that such a popular lake inevitably presents.
