Hirsig No. 2 is a privately owned earth dam located in Hawk Springs, Wyoming, along the North Bear Creek. Built in 1960 for irrigation purposes, the dam stands at 28 feet high with a hydraulic height of 23 feet and a length of 526 feet. Despite its low hazard potential, the dam's condition assessment is rated as poor, raising concerns about its structural integrity and long-term maintenance.

The dam's storage capacity is 84 acre-feet, with a normal storage level of 48 acre-feet and a surface area of 6 acres. The spillway, which is uncontrolled, has a width of 60 feet. The dam's outlet gates consist of one valve. The last inspection, conducted in August 2019, revealed the poor condition of the structure, prompting the need for regular maintenance and potential rehabilitation to ensure its safety and functionality for irrigation purposes in the region.

Although the dam poses a moderate risk, with a risk assessment rating of 3, there are currently no specific risk management measures or emergency action plans in place. Given its importance for irrigation in the area, stakeholders may need to address the dam's poor condition and implement necessary safety measures to mitigate potential risks and ensure the sustainable management of water resources in the region.
