Summary

The dam stands at a height of 37 feet, with a length of 3806 feet and a maximum storage capacity of 3829 acre-feet. The purpose of the dam includes debris control, flood risk reduction, and recreation, serving as a critical infrastructure for managing water resources in the region.

With a fair condition assessment as of April 2018, Chambers Creek WS SCS Site 111 and 112 is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and functionality. The dam has uncontrolled spillways and outlet gates, with a moderate risk assessment of level 3. Despite its age, the structure continues to provide essential flood protection for the surrounding area, demonstrating the importance of proper maintenance and management of water resources in mitigating potential hazards and ensuring community safety.

As water resource and climate enthusiasts, understanding the significance of infrastructure like Chambers Creek WS SCS Site 111 and 112 is crucial for sustainable water management practices. By recognizing the role of dams in flood risk reduction and the impact of regulatory agencies in overseeing their operations, we can work towards building more resilient communities and safeguarding our natural 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.
