Watt Brothers No. 1 is a historic irrigation dam located in Weston, Wyoming, along the Buck Draw Tributary of Buffalo Creek. Built in 1916, this earth dam stands at a height of 28 feet and serves multiple purposes including fire protection, stock watering, and irrigation. With a storage capacity of 120 acre-feet, the dam covers a surface area of 10 acres and has a spillway width of 50 feet.

Managed by a private owner, Watt Brothers No. 1 is regulated by the Wyoming State Engineer's Office and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam's condition assessment is marked as unsatisfactory as of September 2016. However, the risk assessment for this structure is moderate, indicating the need for ongoing monitoring and risk management measures to ensure its continued safety and functionality.

With Liz Cheney as the Congressional representative for the area, Watt Brothers No. 1 remains a vital component of the local water resource infrastructure. As a key feature in the region's irrigation network, this dam plays a crucial role in supporting agricultural activities and water supply for the surrounding community. As climate change continues to impact water resources, the maintenance and management of structures like Watt Brothers No. 1 will become increasingly important in ensuring water security and resilience in the face of changing environmental conditions.
