Blacksmith Fork is a local government-owned dam located in Hyrum, Cache County, Utah. Completed in 1972, this earth dam stands at 14 feet high and spans 260 feet in length, with a primary purpose of hydroelectric power generation. It holds a storage capacity of 42 acre-feet, with a normal storage level of 22 acre-feet, serving the dual purposes of fish and wildlife pond maintenance in addition to hydroelectric power production.

Managed by the Utah Division of Water Rights and regulated by the Federal Energy Regulatory Commission, Blacksmith Fork plays a crucial role in the local ecosystem and energy infrastructure. With a spillway width of 65 feet and a maximum discharge capacity of 1700 cubic feet per second, it is designed to ensure the safety of the surrounding area in the event of significant water flow. While it is currently assessed as having a moderate risk level, regular inspections and emergency action plans are in place to mitigate potential hazards and ensure the dam's structural integrity for years to come.
