Hirsig No. 4 is a privately owned dam located in Hawk Springs, Wyoming, along the North Bear Creek. Built in 1974 by designer J.H. Coffman, this earth dam stands at 27 feet high with a hydraulic height of 22 feet and a structural height of 32 feet. With a primary purpose of serving as a Fish and Wildlife Pond, it also supports irrigation activities in the area.

The dam has a storage capacity of 58 acre-feet and covers a surface area of 5 acres, with a drainage area of 2.6 square miles. It features an uncontrolled spillway with a width of 100 feet and is equipped with a slide (sluice gate) outlet. Despite being classified with a low hazard potential, the dam's condition assessment is rated as poor, indicating a need for improvement and maintenance to ensure its structural integrity and safety.

Given its moderate risk level and the last inspection date in August 2019, stakeholders and regulators need to prioritize the assessment and management of potential hazards associated with Hirsig No. 4. With its importance for fish and wildlife conservation and irrigation, proactive measures must be taken to address the dam's poor condition and minimize risks to the surrounding community and environment.
