Slates No. 1 is a private irrigation dam located in Converse, Wyoming, along the Slates Draw river. Built in 1956, this earth dam stands at 27 feet tall and spans 594 feet in length, with a storage capacity of 77 acre-feet. Despite its age, the dam is still in use for fire protection, stock watering, and irrigation purposes, serving the local community effectively.

The condition assessment of Slates No. 1 indicates poor structural health, with a low hazard potential and moderate risk level, prompting a five-year inspection frequency. The dam features an uncontrolled spillway with a width of 150 feet and a single slide gate outlet for water release. While the dam's emergency action plan readiness and risk management measures are not specified, its location in a low hazard area suggests a manageable level of risk for the surrounding area.

Managed by a private owner and regulated by the state of Wyoming, Slates No. 1 remains an integral part of the local water resource infrastructure. With its historical significance and ongoing role in supporting agriculture and livestock activities in the region, the dam serves as a reminder of the importance of maintaining and monitoring critical water infrastructure for sustainable water resource management in the face of changing climate conditions.
