Summary
This Earth-type dam stands at a height of 28 feet and spans a length of 2890 feet, with a storage capacity of 2125 acre-feet and a drainage area of 3.06 square miles. Despite its age, the dam has not been inspected or rated for condition, but its hazard potential is currently classified as "Not Available" with a high risk assessment rating of 2.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Grays Creek WS SCS Site 7b Dam serves as a crucial infrastructure for flood control in the region. With no spillway and limited emergency preparedness information available, the dam's risk management measures and emergency response protocols are currently not well-documented. Despite these challenges, the dam continues to play a significant role in safeguarding the surrounding areas from potentially devastating flood events.
As water resource and climate enthusiasts, the Grays Creek WS SCS Site 7b Dam presents a fascinating case study in dam infrastructure and risk assessment. Its historical significance, engineering design, and current risk management practices offer valuable insights into the complexities of managing water resources in a changing climate. With ongoing monitoring and potential improvements in emergency response planning, this dam stands as a critical piece of infrastructure in protecting communities and ecosystems from the impacts of extreme weather events.

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.
