Thatcher, also known as Langford Storage, is a private water resource located in Pueblo, Colorado, specifically in the city of Boone. Built in 1971, this earth dam serves primarily for irrigation purposes, with a maximum storage capacity of 85 acre-feet and a normal storage capacity of 40 acre-feet. The dam stands at a height of 12 feet and stretches 1500 feet in length, containing 15 acres of surface area within a drainage area of 7 square miles.

Despite having a low hazard potential, Thatcher poses a high risk due to its condition being unrated and its last inspection dating back to November 1976. The dam does not have a spillway, and there is no emergency action plan (EAP) prepared or updated for the site. This lack of recent oversight and risk management measures underscores the importance of regular inspections and maintenance to ensure the safety and longevity of this crucial water resource in the region.

For water resource and climate enthusiasts, Thatcher offers an intriguing case study in the intersection of infrastructure, regulation, and environmental risk. The dam's location along Haynes Creek and its impact on irrigation, fire protection, and wildlife habitats present a complex ecosystem to monitor and manage. With its proximity to a congressional district and state regulatory agencies like the Department of Water Resources (DWR), Thatcher serves as a focal point for ongoing discussions around dam safety, water allocation, and climate resilience in Colorado. As stakeholders work to address the high risk associated with this structure, there is an opportunity to enhance collaboration, data sharing, and emergency preparedness to safeguard Thatcher and other critical water resources for future generations.
