Summary

Completed in 1987, this earth dam stands at a height of 14 feet and spans 1685 feet, with a storage capacity of 293 acre-feet. The dam serves multiple purposes, including flood risk reduction and recreation, making it a significant asset for the local community.

Managed by the TCEQ, the Chambers Creek WS SCS Site 20a Dam has a satisfactory condition assessment as of December 2017, with a moderate risk rating. The spillway, with a width of 160 feet, is uncontrolled and equipped with two outlet gates. Despite the lack of available hazard potential information, the dam's inspection frequency of 5 years ensures regular monitoring and maintenance to mitigate any potential risks. With a solid design and efficient operation, this dam plays a crucial role in protecting the surrounding area from flooding events and ensuring water resource management in the region.

In case of emergencies, the dam's emergency action plan (EAP) status and risk management measures are not currently available, indicating a potential area for improvement. However, with its strategic location and effective design, the Chambers Creek WS SCS Site 20a Dam stands as a testament to successful collaboration between local government agencies and the USDA NRCS in safeguarding the community against flood risks and promoting sustainable water resource management practices in the region.

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.
