The dam is owned by a private entity and regulated by the Federal Energy Regulatory Commission. With a high hazard potential and a very high risk assessment rating, the safety and management of Holter Dam are of utmost importance. The spillway, with a width of 558 feet, is controlled, and the dam features outlet gates for water release. Despite its age, the dam's condition assessment is not available, highlighting the need for regular inspections and risk management measures.
Holter Dam's location in Lewis and Clark County, Montana, makes it a significant structure in the region's water resource infrastructure. The dam has a controlled spillway and a high hydraulic height of 120 feet, contributing to its flood risk reduction capabilities. As a key hydroelectric facility in the area, the dam provides clean energy while also ensuring water security and flood control for the surrounding communities.
