Lonaconing Reservoir, also known as Lonaconing Water Treatment Plant No.
1, is a vital water supply infrastructure located in Allegany, Maryland. Constructed in 1895, this Earth dam stands at a height of 20 feet and stretches 185 feet in length, with a storage capacity of 22 acre-feet and a surface area of 1.8 acres. The reservoir is primarily regulated by the Maryland Dam Safety agency and serves as a critical source of water for the city of Lonaconing, drawing from the Jackson Run river.
Despite its historical significance and essential role in water supply, the condition assessment of Lonaconing Reservoir is rated as poor, with a high hazard potential. The last inspection in August 2020 revealed the need for significant improvements to ensure the safety and reliability of the structure. With a moderate risk level assigned, it is crucial for local authorities to prioritize maintenance and risk management measures to safeguard this key water resource. As a hub for water resource and climate enthusiasts, Lonaconing Reservoir presents an opportunity for sustainable infrastructure development and environmental stewardship in the face of changing climatic conditions.
