Highway is a privately owned earth dam located in Buffalo, Wyoming, along the Shed Draw river or stream. Built in 1973, the dam stands at a height of 34 feet and has a hydraulic height of 29 feet, serving primarily for irrigation purposes. With a storage capacity of 152 acre-feet, Highway also supports fire protection, stock, small fish ponds, and fish and wildlife habitat in the area.

Despite being regulated and inspected by the State of Wyoming, Highway has a low hazard potential and is currently in fair condition. The dam's spillway is uncontrolled, with a width of 3 feet, and it has no outlet gates. The last inspection was conducted in April 2019, with a frequency of every 5 years. With a moderate risk rating of 3, Highway does not have an Emergency Action Plan (EAP) in place, and there are no inundation maps prepared.

Overall, Highway serves as a crucial infrastructure for water resource management in Johnson County, Wyoming. Its strategic location and design by Clifford J Sanders make it an essential asset for the surrounding community, providing essential water resources for irrigation and supporting the local ecosystem. As climate change continues to impact water availability in the region, Highway's maintenance and monitoring will be critical to ensure its continued functionality and safety for years to come.
