Massae, a privately owned dam located in Uinta, Wyoming, serves the primary purpose of irrigation along the Mill Creek offstream. Constructed in 1968 by designer JOHN A PROFFIT, this earth dam stands at 24 feet high with a hydraulic height of 19 feet, providing a storage capacity of 266 acre-feet. Despite its low hazard potential, the dam's condition assessment is rated as poor, last inspected in July 2019.

With a spillway width of 24 feet and an outlet gate controlled by a single valve, Massae's risk assessment categorizes it as moderate. The dam's overall risk management measures and preparedness for emergencies, such as the creation of an Emergency Action Plan (EAP), remain unspecified. As the dam is regulated by the Wyoming State Engineer's Office and is subject to periodic inspections and enforcement, its role in water resource management in the region is vital.

In the context of the changing climate and increasing pressure on water resources, the maintenance and monitoring of dams like Massae are crucial for ensuring water security and mitigating potential risks. The coordination between private owners, state agencies, and federal representatives, such as Liz Cheney, is essential for the sustainable management of water infrastructure and the protection of communities downstream.
