Summary

With a dam height of 27 feet and a length of 3400 feet, this earth dam has a storage capacity of 1339 acre-feet and covers a surface area of 49.7 acres. Despite not having a spillway, the dam plays a significant role in fire protection, stock, small fish pond management, flood risk reduction, and recreation purposes in the area.

Managed by the local government and regulated by the TCEQ, Cedar Creek WS SCS Site 11 Dam stands as a vital asset in safeguarding the surrounding community from potential flooding events. While the dam's hazard potential is listed as not available, its risk assessment is deemed as high, highlighting the importance of continued monitoring and maintenance to ensure its structural integrity and functionality. With no previous condition rating available, there is a need for further evaluation to assess the overall safety and effectiveness of the dam in mitigating flood risks and protecting the local ecosystem.

As an integral part of the water resource management infrastructure in Texas, Cedar Creek WS SCS Site 11 Dam serves as a testament to the collaborative efforts of various agencies in ensuring the safety and well-being of the community. With its primary purpose being flood risk reduction, the dam's impact extends beyond mere structural engineering to encompass broader environmental and social benefits. By upholding state regulations and conducting regular inspections, the dam remains a critical component in the region's resilience against natural disasters and the preservation of valuable water resources for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
