Wyman, located in Maybell, Colorado, is a privately owned earth dam primarily used for irrigation purposes on the Little Beaver Creek. Completed in 1903, this dam stands at a height of 27 feet and has a storage capacity of 145 acre-feet. Despite its age, Wyman is in fair condition with a low hazard potential, as assessed in 2017.

Managed by the Colorado Department of Water Resources, Wyman is subject to state regulation, inspection, and enforcement. It is equipped with an uncontrolled spillway and has a maximum discharge capacity of 15 cubic feet per second. With a moderate risk level of 3, the dam undergoes inspections every 6 years to ensure its structural integrity and safety. Although it has no associated structures or locks, Wyman plays a crucial role in supporting agricultural activities in the region.

For water resource and climate enthusiasts, Wyman serves as a valuable example of early 20th-century engineering for irrigation purposes. Its historical significance, coupled with its ongoing maintenance and regulation by state authorities, highlights the importance of preserving and managing water infrastructure for sustainable agricultural practices. As climate change continues to impact water resources, dams like Wyman play a vital role in securing water supply for communities in Colorado and beyond.
