With a height of 37 feet and a length of 965 feet, this dam serves a primary purpose of flood risk reduction, storing up to 428 acre-feet of water. Despite not having a spillway, the dam provides essential protection to the surrounding area, with a high hazard potential rating.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Sister Grove Creek WS SCS Site 33 Dam remains under state jurisdiction for permitting, inspection, and enforcement. Although the dam's condition assessment is not rated, it is crucial to monitor its structural integrity due to its high risk assessment rating of 2. With no designated emergency action plan (EAP) or updated inundation maps, stakeholders must prioritize risk management measures and ensure that emergency contacts are up to date to address any potential hazards effectively.
For water resource and climate enthusiasts, the Sister Grove Creek WS SCS Site 33 Dam presents an intriguing case study in dam engineering and management. As a key flood risk reduction structure in the area, understanding its design, storage capacity, and risk assessment can provide valuable insights into the challenges and opportunities of managing water resources in a changing climate. With a focus on enhancing safety measures and risk mitigation strategies, stakeholders can work towards ensuring the long-term sustainability and resilience of this essential infrastructure.
