Navarro Mills Dam, located in Navarro, Texas, was completed in 1963 by the U.S. Army Corps of Engineers as a flood risk reduction structure on Richland Creek. The dam stands at 82 feet high with a storage capacity of over 323,000 acre-feet and serves multiple purposes including flood risk reduction, recreation, and water supply. Despite its benefits, the dam poses a high hazard potential, especially to the nearby City of Purdon, in the event of a breach, with potential downstream flooding reaching depths of a two-story building.
To mitigate risks, the USACE conducts regular inspections, monitoring, and maintenance activities to ensure the dam's structural integrity. Recent repairs to the embankment and spillway have been completed to address potential vulnerabilities, and an Emergency Action Plan is in place to coordinate responses in the event of an emergency. Although the dam faces challenges, ongoing risk management measures and communication with stakeholders aim to safeguard downstream communities and infrastructure from potential flood impacts. For water resource and climate enthusiasts, Navarro Mills Dam presents a case study of proactive risk management in the face of natural hazards.
