Slough Reservoir, located in Fremont, Wyoming, is a federally owned dam managed by the Bureau of Land Management. Built in 1939, this gravity dam serves multiple purposes, including fire protection, stock watering, and small fish pond habitat. With a structural height of 16 feet and a hydraulic height of 12 feet, the reservoir has a storage capacity of 127.91 acre-feet and a normal storage level of 57.1 acre-feet.

Despite its low hazard potential and fair condition assessment, Slough Reservoir is equipped with an uncontrolled spillway and lacks outlet gates. The dam's surrounding area covers approximately 14.13 acres and is primarily fed by the Woods Gulch stream. The reservoir's risk assessment indicates a moderate risk level, prompting a 5-year inspection frequency to ensure its continued safety and functionality. With its historical significance and multi-faceted utility, Slough Reservoir stands as a testament to the enduring importance of water resource management in the face of changing climate patterns.
