Big Creek #5, also known as Silver Lake, is a privately owned irrigation dam located in Mesa County, Colorado. Built in 1894, this earth dam stands at a height of 19 feet and spans 232 feet in length, holding a maximum storage capacity of 183 acre-feet. The dam serves multiple purposes including irrigation, recreation, and water supply for the surrounding area.

Despite being classified with a low hazard potential and fair condition assessment, the dam underwent modifications in 1966 to enhance its hydraulic, mechanical, and structural features. With a controlled spillway width of 26 feet and a maximum discharge capacity of 355 cubic feet per second, Big Creek #5 is equipped to manage excess water flow effectively. The dam is under the regulatory oversight of the Colorado Department of Water Resources, ensuring regular inspections and enforcement of safety measures.

In the event of an emergency, the dam has a slide gate outlet for water release and has a moderate risk assessment rating. While the dam has not had an Emergency Action Plan (EAP) updated recently, it meets regulatory guidelines. With its historical significance and ongoing maintenance, Big Creek #5 remains a crucial water resource infrastructure for the Plateau City area in Colorado.
