Silver Lake, located in Carbon County, Wyoming, is a privately owned reservoir primarily used for irrigation. The earth dam, completed in 1931, stands at a height of 23 feet and has a hydraulic height of 18 feet, providing a storage capacity of 393 acre-feet. The reservoir covers a surface area of 20 acres and has a drainage area of 7.8 square miles, with a maximum discharge capacity of 129 cubic feet per second.

Despite being classified as having a low hazard potential, Silver Lake is considered to be in fair condition as of the last inspection in September 2021. The spillway, which is uncontrolled and 14 feet wide, helps regulate water levels during periods of high inflow. With a moderate risk assessment rating of 3, the dam has undergone regular inspections every five years to ensure its structural integrity and compliance with state regulations. Overall, Silver Lake serves as a vital resource for agricultural water supply in the region, contributing to the sustainability of local water resources amidst changing climate conditions.
