Summary
Completed in 1963, this earth dam stands at a height of 23 feet and spans a length of 1558 feet, providing a storage capacity of 340 acre-feet. Despite its critical role in mitigating flood risks, the dam has not been rated for its current condition assessment and is classified as having a high risk potential.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Grays Creek WS SCS Site 103 Dam plays a crucial role in safeguarding the surrounding area from potential flooding events. With no spillway in place and limited emergency preparedness measures, there is a pressing need for continued inspection and maintenance to ensure the structural integrity of the dam. Climate and water resource enthusiasts will find the data on this dam to be a compelling case study in the intersection of infrastructure, water management, and environmental risk assessment.
As a key component of water resource management in the region, the Grays Creek WS SCS Site 103 Dam represents a convergence of engineering, environmental stewardship, and public safety. With its proximity to the TR-TRINITY RIVER and the potential for high discharge events, the dam serves as a critical barrier against flooding while also posing challenges in terms of risk management and emergency response. The data on this dam offers a rich source of information for those interested in the complexities of water infrastructure and climate adaptation efforts in the face of changing environmental conditions.

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.
