Summary
With a structural height of 33 feet and a length of 1042 feet, this dam holds a normal storage capacity of 150 acre-feet and covers a surface area of 28.5 acres. Situated on Elm Grove Creek, this dam plays a crucial role in protecting the local community from potential flooding events.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), Sister Grove Creek WS SCS Site 14 Dam is inspected regularly to ensure its structural integrity and functionality. The dam is also designed to serve purposes beyond flood risk reduction, including fire protection, stock, or small fish pond creation, and recreational activities. Despite its high hazard potential, with a risk assessment rating of 2, the dam's condition assessment is currently not rated, emphasizing the need for continuous monitoring and management to address potential risks.
For water resource and climate enthusiasts, Sister Grove Creek WS SCS Site 14 Dam offers a fascinating example of engineering and environmental stewardship in action. With its strategic location, design features, and multi-functional capabilities, this dam stands as a testament to the importance of sustainable water management practices in safeguarding communities and ecosystems against natural hazards and promoting responsible water use for various purposes.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
