Maguire, a privately owned dam located in Elbert, Colorado, was completed in 1925 for irrigation purposes. Standing at 17 feet in height and stretching 1800 feet in length, the dam has a storage capacity of 178 acre-feet and a surface area of 21 acres. Situated on the W Bijou Creek-OS river or stream, Maguire serves as a vital resource for water management in the region, with a maximum discharge capacity of 820 cubic feet per second.

While Maguire has a low hazard potential, it carries a high risk assessment rating of 2, suggesting the need for careful monitoring and maintenance. The dam has not been rated for its condition assessment, with the last inspection conducted in September 1991. Despite its age, Maguire remains in operation and regulated by the Colorado Department of Water Resources, with permitting, inspection, and enforcement processes in place to ensure its continued safety and functionality. With its strategic location and historical significance, Maguire stands as a testament to the enduring importance of water resource management in the face of changing climates and evolving needs.
