Hal
May 1, 2024
Hal is a privately owned earth dam located in Torrington, Wyoming, along the Ashenhurst Draw. Completed in 1968 for flood risk reduction, Hal stands at a height of 28 feet and has a hydraulic height of 23 feet. With a storage capacity of 67 acre-feet, the dam serves its purpose effectively with a low hazard potential and fair condition assessment.
Owned by a private entity, Hal is regulated by the Wyoming State Engineer's Office, with state jurisdiction and permitting in place. The dam features an uncontrolled spillway, with a width of 82 feet, and an outlet gate for controlled water release. Although the dam has a moderate risk assessment rating, with a risk level of 3, it meets regulatory guidelines and is inspected every 5 years to ensure its structural integrity and safety.
Despite its age, Hal continues to serve its primary purpose of flood risk reduction, safeguarding the surrounding area from potential inundation. With Liz Cheney representing the Congressional district it resides in, Hal remains a vital infrastructure for water resource management and climate resilience in Platte County, Wyoming.
