Description - Aylesworth Creek Lake is a US Army Corps of Engineers dam control project with a drainage area of 6.2 miles. The project was operationally complete in October 1970 with the reservoir extending 4,600 feet upstream. The recreation area is operated and maintained by the Aylesworth Creek Reservoir Park Authority which is a volunteer organization formed by the boroughs of Archibald and Jermyn. Outdoor activities include swimming, picnicking and hiking.
- The dam controls a drainage area of 6.2 miles. The reservoir extends about 4,600 feet upstream and inundates 87 acres at spillway crest, elevation 1,150 feet above mean sea level. Flood control storage is 1,700 acre feet, equivalent to 5.1 inches of runoff from the drainage area. The earth and rock fill dam has a maximum height above the streambed of 90 feet and a top length of 1,270 feet. An 80-foot wide spillway, having a discharge capacity of 10,000 cubic feet per second, was cut in the south bank. The outlet conduit is uncontrolled and consists of a 490-foot long, 36-inch diameter vitrified clay pipe encased in reinforced concrete. An auxiliary dike was required at the Mayfield divide to contain the reservoir during periods of high pools. The dike is 410 feet long and has a maximum height of 28 feet. The project was operationally complete in October 1970.
Recreation - The recreation area is operated and maintained by the Aylesworth Creek Reservoir Park Authority. The Aylesworth Creek Reservoir Park Authority is a volunteer organization formed by the boroughs of Archbald and Jermyn. Recreational activities include swimming, picnicking and hiking.
