Loup Lake, located in Weld County, Colorado, is a private irrigation reservoir that was completed in 1931 by designer John E. Field. The dam, primarily used for irrigation purposes, is an earth structure standing at a height of 24 feet and length of 1575 feet, with a storage capacity of 877 acre-feet. The reservoir covers a surface area of 93 acres and has a drainage area of 33 square miles, with a maximum discharge rate of 7000 cubic feet per second.

With its significant hazard potential and moderate risk assessment, Loup Lake is regulated and inspected by the Colorado Division of Water Resources, ensuring its structural integrity and safety. The dam is equipped with an uncontrolled spillway that is 165 feet wide, providing necessary flood control measures. The latest inspection in June 2020 deemed the dam's condition satisfactory, with regular inspections scheduled every two years to monitor any changes and maintenance needs. For water resource and climate enthusiasts, Loup Lake presents a fascinating case study of a vital irrigation reservoir in Colorado's agricultural landscape.
