Summary
This earth dam, with a height of 30 feet and a length of 1108 feet, serves to protect the surrounding area from potential flooding along the TR-Post Oak Creek. With a storage capacity of 712 acre-feet, the dam plays a crucial role in managing water flow and mitigating flood risks in the region.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Richland Creek WS SCS Site 126 Dam is equipped with one outlet gate and has a normal storage capacity of 80 acre-feet. Despite its high hazard potential rating of 2, the dam's condition assessment remains unrated. The dam has not been inspected recently, with the last inspection date unknown, raising concerns about its current state and emergency preparedness measures.
Given the dam's high risk potential and the lack of recent inspection data, there is a pressing need for comprehensive risk assessment, condition evaluation, and emergency action planning to ensure the safety and functionality of Richland Creek WS SCS Site 126 Dam. Water resource and climate enthusiasts are encouraged to advocate for regular inspections, maintenance, and risk management measures to safeguard the community and environment from potential disasters related to the dam's operation and structural integrity.

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.
