Poage is a privately owned Earth dam located in Rio Grande, Colorado, specifically in the city of South Fork. Built in 1906 for irrigation purposes, the dam spans 494 feet in length and stands at a height of 27 feet, with a storage capacity of 602 acre-feet. It is situated on the Beaver Creek and is regulated by the Colorado Division of Water Resources, with inspection, permitting, and enforcement activities all being carried out by the state.

The dam has a low hazard potential and is considered to be in satisfactory condition as of the last assessment in July 2017. It features an uncontrolled spillway with a width of 421 feet and is equipped with a single slide (sluice gate) outlet gate. Despite its age, the dam poses a moderate risk level and undergoes inspections every 6 years to ensure its continued safety and functionality.

Water resource and climate enthusiasts will appreciate the historical significance of Poage Dam and its vital role in supporting irrigation, fish and wildlife habitats, and recreational activities in the region. With its unique design and location on the Beaver Creek, Poage serves as a valuable example of early water management infrastructure in Colorado, highlighting the ongoing efforts to maintain and regulate such structures for the benefit of both local communities and the environment.
