Built in 1961, this dam serves multiple purposes including fire protection, stock, and as a small fish pond. With a height of 29 feet and a length of 75 feet, the dam has a storage capacity of 64 acre-feet, with a normal storage level of 41 acre-feet. Situated on TR-Wright Creek, this structure is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state authorities.
Despite its age, Porch #1 has a low hazard potential and has not been rated for its overall condition. While the dam has not been inspected recently and lacks an emergency action plan, it meets the necessary state regulatory requirements for operation. The structure is not overseen by the US Army Corps of Engineers and has not undergone any significant modifications since its construction. With its location in a rural area and limited risk assessment information available, Porch #1 remains a vital component of local water resource management for fire protection and agricultural use.
