Ironworks Creek has three unnamed tributaries, one of which joins within the
Churchville Reservoir, a lake constructed in 1942 by damming up a section of the creek. The
Churchville Nature Center, a facility of the Bucks County Parks and Recreation that operates a 55 acre environmental education center and nature preserve adjacent to the reservoir, works on protecting the 700+ acres of the watershed formed around the Ironworks Creek. ==Geology==
