Churchville reservoir is an man-made freshwater reservoir located inBucks County, PA. It was created by damming the Mill Creek in 1942 to act as a reserve of municipal water. In times of low water it could be emptied through Iron Works Creek and from there into Mill Creek, which eventually empties into the Neshaminy Creek. Once the water reaches the Neshaminy, it can be withdrawn through the pumping station at Neshaminy Falls. When the reservoir was created it was surrounded by a rural land and few houses. By the late 1950s land development had expanded and new residents began to move to the Churchville area. The Churchville Nature center was one of the first locations selected due to its diversity of habitat including a woodlot, open field, meadow-land, and the reservoir.
Cache is located in Churchville Perserve, a bit of a ways from the wannabe SEPTA Railroad tracks.
