Summary
Completed in 1972, this earth dam stands at a height of 40 feet and stretches 2633 feet in length, with a storage capacity of 4729 acre-feet. Its purpose extends beyond flood control to include debris control, irrigation, and maintaining a normal storage capacity of 200 acre-feet.
The dam's spillway, with a width of 302 feet, is uncontrolled, allowing for the safe release of excess water during heavy rainfall events. It underwent structural modifications in 2010, enhancing its overall performance and resilience. While the dam's hazard potential is not available, its risk assessment stands at a moderate level (3), indicating a need for continual monitoring and management to ensure its effectiveness in mitigating potential flooding risks.
Despite its age, Chambers Creek WS SCS Site 75b Dam remains a crucial component in the water resource infrastructure of the region, serving as a critical line of defense against flooding and safeguarding downstream communities. With state regulatory oversight from TCEQ and regular inspections in place, the dam continues to fulfill its purpose of protecting lives and properties from the impacts of extreme weather events, showcasing the importance of proactive management of water resources in the face of a changing climate.

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.
