Dilts Ranch 1-20 is a privately owned Earth dam located in Converse, Wyoming, along Antelope Creek. Designed by Russ Dahlgren and completed in 2015, this dam stands at a height of 18.5 feet and has a storage capacity of 130 acre-feet. With a low hazard potential and fair condition assessment, this dam serves primarily for purposes other than flood control or water supply.

Despite its relatively small size, Dilts Ranch 1-20 plays a crucial role in local water resource management, storing water for agricultural or irrigation purposes. The dam's uncontrolled spillway and lack of outlet gates indicate a simple design that effectively manages the flow of water. Regular inspections have been conducted, with the last assessment in June 2021, ensuring the dam's continued functionality and safety.

Located in a moderate risk area, Dilts Ranch 1-20 is subject to state regulation, inspection, and enforcement to mitigate any potential hazards. With Liz Cheney as the Congressional representative for the area, the dam's operations are overseen by the Wyoming State Engineer's Office. As a key infrastructure for water management in the region, Dilts Ranch 1-20 highlights the importance of proper dam maintenance and monitoring in mitigating potential risks associated with climate change and water resource management.
