Summary

Completed in 1970, this earth dam stands at a height of 52 feet and spans 4700 feet, with a storage capacity of 8538 acre-feet. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity.

Despite its fair condition assessment in 2016, the dam's hazard potential is not available, and it has a moderate risk rating. The spillway, with a width of 312 feet, is uncontrolled, and the dam features slide and uncontrolled outlet gates. The dam's primary purpose is flood risk reduction, serving the local community under the ownership of a local government entity. With a drainage area of 12.5 square miles and a maximum discharge capacity of 9944 cubic feet per second, Castleman Creek WS SCS Site 1 Dam plays a crucial role in managing water resources in the region.

In recent years, the dam underwent structural modifications in 2011 to enhance its performance. The dam's emergency action plan (EAP) status is not available, and there is no inundation map prepared for the area. While the dam's risk management measures and DSAC assignment date are unspecified, the structure continues to play a vital role in water resource management and climate resilience efforts in McLennan County.

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.
