Donahue, located in Laramie, Wyoming, is a privately owned earth dam primarily used for irrigation purposes along the Little Horse Creek. Built in 1953 by designer T.H. Baldwin, this structure stands at a height of 20 feet with a hydraulic height of 15 feet and a length of 350 feet. Despite its low hazard potential, Donahue is currently assessed to be in poor condition, highlighting the need for maintenance and repairs to ensure its structural integrity.

With a storage capacity of 119 acre-feet and a normal storage level of 56 acre-feet, Donahue plays a crucial role in water resource management for the surrounding area. The dam also serves secondary purposes such as fire protection, stock watering, and small fish pond maintenance. Operating under state jurisdiction and regulatory oversight, Donahue is subject to regular inspections to uphold safety standards and mitigate any potential risks associated with its condition.

Although Donahue's risk assessment is moderate, stakeholders should prioritize implementing risk management measures to address the dam's poor condition and ensure its long-term functionality. Given its significance in irrigation and water storage, proactive maintenance and emergency preparedness are essential to safeguarding this vital water resource for the community and maintaining a sustainable water supply in the region.
