Brett Gray, also known as Sanborn Dam, is a privately owned irrigation structure located in Lincoln County, Colorado, along the Steels Fork river. Built in 1939 by the USDA NRCS, this earth dam stands at a height of 23 feet and serves the primary purpose of irrigation, with a storage capacity of 570 acre-feet and a drainage area of 48 square miles. Despite being rated as having low hazard potential, Brett Gray faces a high risk level due to its age and lack of recent condition assessments.

Operated and regulated by the Colorado Department of Water Resources, Brett Gray has state jurisdiction and is subject to permitting, inspection, and enforcement measures to ensure its safety and compliance with regulations. The dam does not have a spillway and is not equipped with outlet gates or locks, highlighting its simple structure and design. Although last inspected in 1990, the dam's risk management measures and emergency action plan status are unknown, raising concerns about its ability to address potential hazards and emergencies effectively.

For water resource and climate enthusiasts, Brett Gray presents an intriguing case study of an aging irrigation dam in rural Colorado. The dam's historical significance, engineering design, and risk assessment provide valuable insights into the challenges and considerations involved in managing and maintaining water infrastructure in a changing climate. As efforts to address aging infrastructure and improve dam safety continue, Brett Gray serves as a reminder of the importance of proactive maintenance and monitoring to ensure the reliability and resilience of our water resources.
