Hillberry, located in Washakie County, Wyoming, is a privately owned Earth dam built in 1947 for irrigation purposes on Gooseberry Creek. With a structural height of 26 feet and a hydraulic height of 21 feet, Hillberry has a storage capacity of 136 acre-feet and covers a surface area of 10 acres. Despite its poor condition assessment, the dam has a low hazard potential and is regulated and inspected by the State of Wyoming.

The dam features an uncontrolled spillway with a width of 30 feet and a slide (sluice gate) outlet gate. Although the last inspection was conducted in July 2021, the dam is scheduled for inspection every 5 years. The risk assessment for Hillberry is rated as moderate, with no emergency action plan in place. The dam's location in Worland, Wyoming, along with its strategic role in providing irrigation water, makes it a key structure for water resource management in the region. As climate change threatens water availability, maintaining and improving the infrastructure of dams like Hillberry will be essential for sustainable water management in the future.

Efforts to address the poor condition assessment and mitigate moderate risks associated with Hillberry will be crucial for ensuring the safety and reliability of the dam in the face of changing climate conditions. With Liz Cheney as the Congressional representative for the area, there is an opportunity for collaboration between federal, state, and local agencies to strengthen the dam's resilience and enhance its capacity to withstand potential hazards. By investing in necessary upgrades and maintenance measures, Hillberry can continue to play a vital role in supporting agricultural activities and water resource management in Washakie County and beyond.
