Bergen West Dike, also known as Bergen #1, is a private-owned structure located in Jefferson County, Colorado, specifically in the city of Lakewood. Completed in 1888, this earth-type dam stands at a height of 25 feet and has a hydraulic height of 15 feet, serving primarily for irrigation purposes along the Weaver Gulch. With a storage capacity of 505 acre-feet and a moderate hazard potential, the dam is regulated, inspected, and enforced by the Colorado Department of Water Resources to ensure its safety and functionality.

Despite its fair condition assessment as of May 2020, Bergen West Dike remains a vital component for water resource management and recreational activities in the area. With a low hazard potential and a moderate risk assessment rating, the dam plays a crucial role in regulating the flow of water and providing essential irrigation for the surrounding landscape. Its uncontrolled spillway and 1600-foot length contribute to its capacity to manage water discharge effectively during periods of high flow.

While the dam's emergency action plan status and risk management measures remain unspecified, its consistent inspections and adherence to state regulations ensure its continued operation and safety for the local community. Maintaining a balance between irrigation needs and environmental considerations, Bergen West Dike exemplifies the importance of sustainable water resource management in the face of changing climate patterns and increasing water demands in the region.
