Located in Longmont, Colorado, the Walker dam serves the primary purpose of irrigation and was completed in 1892. This earth dam stands at a height of 8 feet and has a length of 750 feet, with a storage capacity of 142 acre-feet. The dam, situated on the TR. of Spring Gulch Creek, is regulated by the Colorado Department of Water Resources and is subject to state permitting, inspection, and enforcement.

With a low hazard potential and a moderate risk assessment rating, the Walker dam has not been rated for its current condition. The last inspection took place in October 1991, with a scheduled inspection frequency of 6 years. While the dam has not been modified in recent years, it is equipped with an uncontrolled spillway and is designed to handle a maximum discharge of 83 cubic feet per second. Although the dam is privately owned, it plays a crucial role in the irrigation infrastructure of the region, contributing to the management of water resources in Boulder County.
