Bergen East, also known as Bergen #2, is a privately owned irrigation structure located in Morrison, Colorado. This Earth-type dam was completed in 1874 and stands at a height of 40 feet, with a length of 1300 feet. It serves the primary purpose of irrigation and recreation, with a storage capacity of 1150 acre-feet and a surface area of 41 acres. The dam is situated on Weaver Gulch and is regulated by the Colorado Department of Water Resources, with inspections and enforcement carried out regularly to ensure its structural integrity.

With a high hazard potential and a satisfactory condition assessment, Bergen East has undergone multiple structural modifications over the years to enhance its safety and functionality. The dam has a spillway width of 20 feet and a maximum discharge capacity of 2600 cubic feet per second. While it poses a moderate risk, measures have been put in place to manage any potential emergencies, although the Emergency Action Plan (EAP) may need updating. The dam's location in Jefferson County, Colorado, makes it a valuable resource for water management in the region, highlighting the importance of maintaining its safety and efficiency for the surrounding communities.
