Hartford is a privately owned irrigation dam located in Weld County, Colorado, along the St. Vrain River. Built in 1890, this earth dam stands at a height of 9 feet and stretches 1150 feet in length, providing a storage capacity of 113 acre-feet for agricultural use. Despite its age, Hartford has a low hazard potential and has not been rated for condition assessment. The last inspection of the dam took place in October 1984, with a recommended inspection frequency of every 6 years.

While Hartford may not pose an immediate threat, its location in a high-risk area highlights the need for ongoing risk management measures. The dam is not under the jurisdiction of the US Army Corps of Engineers and is regulated by the Colorado Division of Water Resources. With a surface area of 13 acres and a drainage area of 0, Hartford serves primarily for irrigation purposes. The dam does not have a spillway and has not been rated for its emergency action plan or compliance with guidelines.

As water resource and climate enthusiasts, the data on Hartford's infrastructure serves as a reminder of the importance of maintaining and monitoring aging dams for potential risks and hazards. While Hartford may currently have a low hazard potential, the surrounding area's high risk assessment underscores the need for continued oversight and risk management measures to ensure the safety and functionality of this vital water resource infrastructure in Weld County, Colorado.
