Built in 1960, this dam has a primary purpose of fire protection, stock, or small fish pond. With a height of 20 feet and a length of 200 feet, Clamhopper #1 has a storage capacity of 51 acre-feet and a normal storage level of 26 acre-feet. Situated on TR-DRAG CREEK, this dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and current "Not Rated" condition assessment, Clamhopper #1's emergency action plan status, risk assessment, and management measures are not available. The dam, managed by a private entity, does not fall under federal agency ownership or funding. Its location in a remote area with no nearby city underscores the importance of proper maintenance and monitoring to ensure its effectiveness in providing fire protection and sustaining water resources for stock or small fish pond purposes. As a crucial component of the local water infrastructure, continued attention to Clamhopper #1 is essential for the community and environment it serves.
