In 1964, the Spruce Run Reservoir Dam was built by the New Jersey Water Supply Authority, forming the Spruce Run Reservoir.[4] The reservoir is the third largest in the state and is encompassed by the Spruce Run Recreation Area.[5] The source of the stream is protected, located in Crystal Springs Preserve, a county park.[6] In addition, several sections of the stream are protected for fishing, hiking and nature observation.[7]
