Located in Jefferson County, Colorado, the Leyden Dam, also known as Farmers Highline No 3, was completed in 1902 for the primary purpose of flood risk reduction along Leyden Creek. This earth dam stands at a height of 37 feet and has a structural height of 47 feet, with a length of 1,545 feet and a storage capacity of 1,300 acre-feet. The dam is regulated by the Colorado Department of Water Resources and is subject to state permitting, inspection, and enforcement to ensure its safety and effectiveness in flood control.

With a hazard potential rated as high, the Leyden Dam has been assessed as satisfactory in its condition as of the last inspection in February 2020. The dam's risk assessment is moderate, indicating a level 3 risk, and it falls under the jurisdiction of the Omaha District of the US Army Corps of Engineers. In case of emergencies, there is a need for an Emergency Action Plan (EAP) to be prepared and regularly reviewed. Overall, Leyden Dam serves not only as a flood risk reduction measure but also provides recreational opportunities for the community in Arvada while being a critical component of water resource management in the region.
