Wilson, also known as South Slope #8, is a significant earth dam located in El Paso, Colorado, that serves as a crucial water supply source for the city of Pueblo. Completed in 1897, this structure stands at a height of 20 feet and has a storage capacity of 1340 acre-feet, with a normal storage level of 669 acre-feet. The dam spans 1650 feet in length and covers a surface area of 83 acres, with a maximum discharge capacity of 3800 cubic feet per second.

Managed by the local government and regulated by the Colorado Department of Water Resources, Wilson is inspected biennially to ensure its structural integrity and overall condition. Despite being classified as having a significant hazard potential, the dam has been assessed as satisfactory and meets moderate risk management standards. In the event of an emergency, an Emergency Action Plan (EAP) is in place, with the last revision conducted in December 2020. With its primary purpose being water supply, Wilson plays a vital role in sustaining the surrounding ecosystem and supporting fish and wildlife populations in the area.
