Summary
This earth dam stands at a height of 28 feet and spans a length of 2030 feet, with a storage capacity of 1331 acre-feet. Despite lacking a spillway, the dam serves its primary purpose effectively, with a normal storage capacity of 104 acre-feet and a surface area of 30.2 acres.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), Richland Creek WS SCS Site 21 Dam has not been rated for condition assessment but is deemed to have a high risk level. With one outlet gate and a buttress core type, the dam has withstood the test of time since its completion and remains vital for flood risk mitigation in the area. While hazard potential and emergency preparedness information is not available, the dam's presence underscores the importance of water resource management and climate resilience in this region.
For water resource and climate enthusiasts, Richland Creek WS SCS Site 21 Dam offers a fascinating case study in flood risk reduction and dam infrastructure in Texas. With its historical significance, structural details, and risk assessment data, this dam serves as a reminder of the critical role that such structures play in safeguarding communities and ecosystems from the impacts of extreme weather events and changing climatic conditions.

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.
