Pikes Creek Reservoir existed by the 1930s. In around 1932, 80 percent of the reservoir's water supply became exhausted, causing water restrictions to be put in place in Wilkes-Barre. The reservoir was opened to fishing with some limitations in 1998.

As of 2013, the Pennsylvania-American Water Company owns Pikes Creek Reservoir. In the spring of 2013, Pennsylvania Fish and Boat Commission biologists did a fish survey of the reservoir. The main purpose of the reservoir is as a supply of potable water. The Pennsylvania-American Water Company has a facility on the reservoir capable of processing 16 million gallons of water per day, but it normally processes around 9 million gallons.
