Managed by the Pennsylvania Department of Environmental Protection, this dam was completed in 1990 and serves primarily for recreational purposes. With a dam height of 27 feet and a length of 785 feet, Greenwalt has a storage capacity of 171 acre-feet and a normal storage level of 92 acre-feet, covering a surface area of 15 acres and draining an area of 2.2 square miles.
The dam on Crabtree Creek has a significant hazard potential, although its condition assessment is currently marked as 'Not Rated'. Despite being uninspected since February 2018, the dam has a scheduled inspection frequency of every 2 years. The surrounding area does not have an Emergency Action Plan (EAP) in place, raising concerns about the readiness for any potential emergencies. With its unique earth dam type and buttress core design, Greenwalt stands as a crucial water resource in the region, attracting water resource and climate enthusiasts alike.
For those interested in water resources and climate change, Greenwalt offers a fascinating study in dam construction and management. Its location in a scenic environment in Unity Township provides an ideal setting for recreational activities and wildlife habitat. However, the dam's significant hazard potential and lack of recent inspection raise questions about its long-term safety and management strategies. Greenwalt serves as a reminder of the importance of proper infrastructure maintenance and emergency preparedness in the face of changing environmental conditions.
