Churchville Reservoir, reservoir in Bucks County, Pennsylvania, United States

Churchville Reservoir is a man-made lake in Bucks County, Pennsylvania, created by damming Mill Creek to store water. The body of water spans roughly 73 hectares and sits surrounded by woods, meadows, and open fields, with roads crossing over its surface.

The reservoir was constructed in 1942 to ensure reliable water supplies during dry periods for the local community. Its creation coincided with a period of expansion in regional water systems across the area.

Fishing is banned in the reservoir, which Aqua Pennsylvania holds as a water reserve. Elm Avenue and Churchville Lane cross over the water, so drivers pass directly above it. The Churchville Nature Center on Churchville Lane sits next to the reservoir and gives access to the surrounding grounds.

In times of low water, the reservoir could be drained through Iron Works Creek into Mill Creek and on to the Neshaminy Creek, where a pumping station at Neshaminy Falls could draw the water back out. The reservoir is owned by Aqua Pennsylvania, and fishing in it is banned.
