Lake Churchill was created in 1971 from a stream and a small, deep pond. This was done by Prudential, as the company initiated development of the Churchill Town Sector. Montgomery County required installation of the dam and thus the creation of the lake, to serve as a stormwater-management facility for the majority of the Town Sector. Lake Churchill handles stormwater from a watershed of approximately 720 acres.
While the 18-acre lake continues to serve as a stormwater-management facility, the Churchill Community Foundation’s Board of Directors strives to make the lake a valuable amenity for the entire community. The lake’s natural forebay has trapped a significant amount of sediment from the middle of the lake, where there is still a very generous water capacity. Although the lake is not stocked, it contains a healthy variety of fish and is home to numerous other species of wildlife. The lake is situated between Wynnfield Drive, Father Hurley Boulevard, the Waters Landing community, and Laurel Hill Way. The lake is kept at a constant level, with the overflow draining directly to Little Lake Seneca.
