Bonneville Reservoir, located in Fremont County, Wyoming, is a Federal-owned water resource managed by the Bureau of Land Management. Built in 1941, this gravity dam serves multiple purposes including fire protection, stock watering, and as a small fish pond. With a structural height of 26 feet and a hydraulic height of 22 feet, the reservoir has a storage capacity of 156.1 acre-feet and covers a surface area of 15.9 acres.

Despite its low hazard potential, Bonneville Reservoir is considered to be in poor condition and poses a high risk, according to a recent assessment. The dam lacks a spillway, and its inspection frequency is set at five years. The reservoir is primarily regulated by the State of Wyoming through the State Engineer's Office, with regular inspections, permitting, and enforcement in place.

As a key component of the water infrastructure in the region, Bonneville Reservoir plays a crucial role in providing water resources for firefighting, livestock, and recreational activities. With its historical significance dating back to the early 20th century, efforts are being made to enhance the safety and functionality of the dam to ensure the continued protection and management of this valuable water resource in Wyoming.
