Summary
Designed by the USDA NRCS, this earth dam stands at a height of 28 feet and stretches over 1219 feet in length, providing a storage capacity of 277 acre-feet and a surface area of 10 acres. Despite its lack of a spillway, the dam has not experienced any hazard potential assessments, and its condition remains unrated.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Richland Creek WS SCS Site 4a Dam serves as a critical infrastructure for managing water resources in the area. With a high risk assessment rating of 2, there is a need for further evaluation and potential risk management measures to ensure the dam's continued effectiveness in flood risk reduction. While there are no associated structures or locks, the dam's single outlet gate allows for controlled water release when needed.
For water resource and climate enthusiasts, the Richland Creek WS SCS Site 4a Dam presents an intriguing case study in dam infrastructure and flood risk management. With its historical significance and continued role in protecting the surrounding areas from potential flooding, this earth dam serves as a vital piece of the water management puzzle in Limestone County, Texas. As climate change impacts continue to affect water resources, the importance of maintaining and assessing the condition of structures like this dam becomes increasingly crucial for sustainable water management practices.

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.
