Summary
Completed in 1953, this Earth dam stands at a height of 50 feet and stretches 2000 feet in length, offering a maximum storage capacity of 3000 acre-feet. The dam serves multiple purposes including fire protection, stock or small fish pond, flood risk reduction, and recreation, making it a versatile asset for the community.
Managed by the TCEQ and regulated by the state of Texas, the dam features an uncontrolled spillway with a width of 260 feet and outlet gates for efficient water flow management. With a moderate risk assessment rating, the dam has not been rated for condition assessment, but it undergoes inspections every 5 years to ensure its safety and functionality. Despite its relatively small drainage area of 5.02 square miles, the dam plays a crucial role in safeguarding the surrounding area from potential flooding events and contributes to the overall water resource management in the region.
Sister Grove Creek WS SCS Site 9 Dam is an essential infrastructure owned by the local government, serving as a testament to the collaborative efforts in flood risk reduction and water resource management. With its strategic location in Sister Grove Creek and a history dating back to the mid-20th century, this dam stands as a symbol of resilience and innovation in the face of climate challenges. As water resource and climate enthusiasts, the intricate design and functionality of this dam provide valuable insights into the intersection of engineering, environmental stewardship, and community resilience in ensuring a sustainable future for generations to come.

Dam Data Reference
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.
