Enl. Ellie, located in Campbell County, Wyoming, is a privately owned earth dam designed by Hugh Lowham for irrigation purposes. Completed in 2007, this dam stands at a height of 31 feet with a hydraulic height of 24 feet, providing a storage capacity of 171 acre-feet for water from the Blister Draw river. With a surface area of 10 acres and a drainage area of 0.26 square miles, Enl. Ellie serves multiple purposes including fire protection, stock watering, and creating a small fish pond in addition to irrigation.

Despite its low hazard potential and fair condition assessment as of June 2018, Enl. Ellie has a moderate risk rating of 3. The dam features an uncontrolled spillway with a width of 2 feet, and is equipped with a single valve outlet gate for water release. The dam undergoes inspections every 5 years to ensure its structural integrity and safety standards are maintained. However, there are currently no emergency action plans in place, raising concerns about the readiness for potential risks and the need for updated protocols to meet guidelines.

Enl. Ellie plays a crucial role in water resource management in the region, contributing to agricultural activities and environmental sustainability in the area. Climate and water resource enthusiasts may find interest in monitoring the ongoing risk assessment and management measures for this dam, as well as advocating for enhanced emergency preparedness protocols to safeguard against potential hazards and ensure the long-term resilience of this vital infrastructure.
