Located in Weld County, Colorado, the McKay dam stands as a testament to the importance of water resources for irrigation in the region. Completed in 1886, this private-owned earth dam spans 450 feet in length and reaches a height of 9 feet, with a storage capacity of 92 acre-feet. Situated on the Howlett Gulch-TR river or stream, McKay serves as a crucial infrastructure for agricultural water management in the area.

Despite its age, McKay dam remains in a relatively low hazard potential category, with a condition assessment that is yet to be rated. However, the risk assessment for this structure is considered high, emphasizing the need for proper risk management measures to be put in place. With a history dating back over a century, McKay continues to play a vital role in sustaining the irrigation needs of the surrounding community.

As climate change poses new challenges to water resources management, the importance of structures like McKay in ensuring sustainable water supply for agricultural purposes cannot be overstated. With state regulation and oversight in place, including permitting, inspection, and enforcement, McKay serves as a key example of how historic dams can adapt and continue to contribute to water resource management in a changing climate.
