Summary
Completed in 1954, this earth dam stands at a height of 32 feet and spans 1773 feet, providing a storage capacity of 1433 acre-feet. The dam's primary purpose is flood risk reduction, with a spillway width of 204 feet to control water flow during peak discharge events.
The dam, situated on Willow Creek, is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement measures to ensure its structural integrity and operational readiness. Despite its age, the dam's hazard potential is marked as "Not Available" with a moderate risk assessment rating. The presence of one slide gate and three uncontrolled outlets allows for controlled water release in emergency situations, contributing to the overall safety of the surrounding community.
For water resource and climate enthusiasts, Grays Creek WS SCS Site 9 Dam serves as a significant example of infrastructure designed to protect against flooding and manage water flow in a vulnerable region. With its historical significance, regulatory oversight, and moderate risk assessment, this dam stands as a testament to the ongoing efforts to safeguard communities from the impacts of extreme weather events and ensure sustainable water resource management in Texas.

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.
