Situated on TR-Pennel Creek in Fallon County, this dam has a height of 20 feet and a length of 420 feet, with a storage capacity of 62 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with regular inspections and enforcement to ensure safety and compliance with state regulations.
Despite being classified as having a low hazard potential, Halmans #1 has not been rated for its condition assessment. There is currently no Emergency Action Plan (EAP) in place for the dam, and no risk assessment or management measures have been documented. The dam does not belong to the United States Army Corps of Engineers (USACE) and has not undergone any modifications or updates in recent years. With its strategic location for irrigation purposes and state-regulated status, Halmans #1 presents an interesting case study for water resource and climate enthusiasts interested in the management and maintenance of dams in Montana.
