Summary
Built in 1971 by the USDA NRCS, this earth dam stands at 30 feet high and stretches 1383 feet in length, providing a maximum storage capacity of 740 acre-feet. With a normal storage of 57 acre-feet and a drainage area of 1.78 square miles, the dam plays a vital role in managing water flow and reducing the risk of flooding in the surrounding area.
Despite its age, Richland Creek WS SCS Site 108 Dam remains in moderate condition, with a hazard potential rating of "Not Available" and a risk assessment score of 3. The dam features an uncontrolled spillway with a width of 142 feet and two uncontrolled outlet gates. While the dam is not owned or funded by federal agencies, it is regulated, permitted, inspected, and enforced by the Texas Commission on Environmental Quality (TCEQ), ensuring its compliance with state regulations and safety standards.
For water resource and climate enthusiasts, Richland Creek WS SCS Site 108 Dam represents a significant piece of infrastructure designed to protect communities from the impacts of extreme weather events. As climate change continues to challenge traditional water management practices, dams like this one play a crucial role in enhancing resilience and safeguarding against flood risks in the face of a changing climate.

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.
