Summary

This earth dam stands at 36 feet tall and spans 2545 feet, with a storage capacity of 1754 acre-feet and a drainage area of 3.35 square miles. The dam features an uncontrolled spillway 132 feet wide and outlet gates including a slide gate and two uncontrolled gates.

Despite being constructed over six decades ago, Chambers Creek WS SCS Site 38 Dam underwent a structural modification in 2010 to ensure its continued effectiveness in flood risk reduction. While the dam's hazard potential, condition assessment, and emergency action plan status are not currently available, its risk assessment is moderate. The dam is regulated, inspected, and enforced by the Texas Commission on Environmental Quality (TCEQ), ensuring it meets state permitting and inspection requirements.

This dam represents a critical piece of infrastructure in Johnson County's water resource management system, offering protection against floods and helping to safeguard the surrounding communities. With a history of proactive maintenance and adherence to state regulations, Chambers Creek WS SCS Site 38 Dam remains a vital asset in the region's efforts to mitigate the impacts of extreme weather events and ensure the safety of residents and property in the area.

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.
