Glowmill, located in Goshen County, Wyoming, is a private irrigation dam on Box Elder Creek that was completed in 1976. Designed by J.H. Coffman, this Earth-type dam stands at a height of 17 feet and has a storage capacity of 1561 acre-feet. With a significant hazard potential and a poor condition assessment as of the last inspection in May 2017, Glowmill poses moderate risk and is in need of maintenance and upgrades to ensure its safety and functionality.

Despite being a privately owned structure, Glowmill is regulated by the state of Wyoming, with permitting, inspection, and enforcement responsibilities falling under the State Engineer's Office. The dam's purpose is primarily for irrigation, serving the surrounding agricultural community by providing water storage and distribution. The spillway, with a width of 200 feet, is uncontrolled, and the dam features other controlled outlet gates to manage water release.

As an essential component of the water resource infrastructure in the region, Glowmill plays a crucial role in supporting agricultural activities in the area. Climate and water resource enthusiasts would find this dam noteworthy for its design, purpose, and the need for ongoing maintenance to ensure its continued safe operation. With its location on Box Elder Creek and its significant storage capacity, Glowmill represents a vital piece of Wyoming's water management system that requires attention to ensure its long-term reliability and safety.
