Built in 1974 by the USDA NRCS, this earth dam stands at a height of 29 feet and spans 586 feet in length, with a primary purpose of providing fire protection, stock, and small fish pond. The dam has a storage capacity of 72 acre-feet, with a normal storage level of 59 acre-feet, and covers a surface area of 24 acres.
Managed by the Texas Commission on Environmental Quality (TCEQ), Brenni Lake Dam is regulated, permitted, inspected, and enforced by the state. Despite being rated as high risk due to its hazard potential, the condition of the dam is currently not rated, and it lacks an emergency action plan. With no spillway and a lack of drainage area, the dam poses potential risks that are being closely monitored by regulatory agencies to ensure public safety and environmental protection in the surrounding area.
Water resource and climate enthusiasts can appreciate Brenni Lake Dam for its role in providing essential services like fire protection, recreation, and stock water supply. While the dam's risk potential is a concern, ongoing oversight and regulation by the state demonstrate a commitment to maintaining the dam's integrity and safeguarding the surrounding community and ecosystem. As a key feature in the watershed of TR-LONG BRANCH, this dam serves as a reminder of the importance of sustainable water resource management in the face of changing climate conditions.
