Summary
Completed in 1963, this earth dam reaches a height of 33 feet and stretches for 4850 feet, providing flood risk reduction benefits to the surrounding area. With a storage capacity of 4646 acre-feet, the dam serves a vital role in managing water flow and protecting the community from potential inundation.
Operated and regulated by the Texas Commission on Environmental Quality (TCEQ), Richland Creek WS SCS Site 119a Dam is recognized for its high hazard potential and its importance in safeguarding the local residents and environment from the impacts of extreme weather events. Despite its significant risk profile, the dam is not currently rated for its condition, highlighting the need for ongoing assessment and maintenance to ensure its effectiveness in the face of changing climate patterns. As a key flood control structure in the region, this dam plays a critical role in water resource management and climate resilience efforts.
As water resource and climate enthusiasts continue to monitor the impact of climate change on our infrastructure, Richland Creek WS SCS Site 119a Dam stands as a prime example of the importance of proactive risk management and investment in resilient infrastructure. With its strategic location and design, this dam not only provides flood protection but also serves as a testament to the collaborative efforts between local government agencies, federal design and construction entities, and regulatory bodies in ensuring the safety and well-being of the community in the face of evolving environmental challenges.

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.
