Kimberly, located in Johnson, Wyoming, is a privately owned dam with a primary purpose of fire protection, stock, or small fish pond, as well as flood risk reduction. Completed in 1973, this earth dam stands at 29 feet in height and spans 150 feet in length, with a storage capacity of 43 acre-feet. Situated on Cow Creek, this structure serves the community of Arvada and is regulated by the Wyoming State Engineer's Office, with state permitting, inspection, and enforcement in place.

Although Kimberly has a low hazard potential and is currently assessed to be in fair condition, it presents a moderate risk level due to its location and design features. The dam features an uncontrolled spillway and one outlet gate, with a maximum discharge capacity of 73 cubic feet per second. Despite its relatively small surface area of 3 acres, this dam plays a crucial role in providing essential services for the local area, ensuring fire protection and water supply for livestock and small fish ponds. With regular inspections and a history of compliance with state regulations, Kimberly remains a vital asset for water resource management in the region.
