Raystown Lake, Reservoir and recreation area in Pennsylvania, United States.

Raystown Lake is a reservoir in Pennsylvania that extends across 8300 acres (3360 ha) and offers 27 miles (43 km) of water surface. A total of 14 public beach areas and numerous coves divide the shoreline into different sections for water sports and recreation.

The facility was created starting in 1968 through the construction of a dam on the Raystown Branch of the Juniata River, and flooding began in 1973. The project aimed to reduce valley flooding while providing drinking water and recreation areas for the region.

The name Raystown comes from an early settler who established himself in this valley during the 18th century. Today anglers and sailors use the water mainly between spring and autumn, when small motor boats and kayaks spread across the cove surfaces.

On warm summer days the public swimming spots can become very crowded, while early morning hours offer much more quiet. Visitors who wish to experience the water beyond the shore will find several docking areas for small boats and paddles along the different shore zones.

Beneath the water surface lie several sunken building foundations and old road sections from the time before the flooding. These artificial structures now attract large fish and are specifically targeted by experienced anglers.
