Ramsbottom, a private-owned water resource in Johnson, Wyoming, serves multiple purposes including fire protection, stock watering, and small fish pond irrigation. Completed in 1970, this earth dam stands at 30 feet high with a hydraulic height of 25 feet and a structural height of 34 feet. It holds a maximum storage capacity of 72 acre-feet, with a normal storage level of 35 acre-feet and a surface area of 7 acres.

Despite its low hazard potential, Ramsbottom is rated as having poor condition as of the last inspection in August 2019. The dam features an uncontrolled spillway with a width of 70 feet and one uncontrolled outlet gate. With a moderate risk assessment level of 3, there is a need for improved risk management measures to ensure the safety and integrity of this important water resource. Given its location in the Cottonwood Draw and its critical role in the local ecosystem, maintaining Ramsbottom is vital for the surrounding community and environment.
