Summary
Designed by the USDA NRCS, this earth dam stands at a height of 32 feet and spans 3,840 feet in length, providing a storage capacity of 8,800 acre-feet. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and functionality.
With a moderate risk assessment rating, the San Diego-Rosita Cks WS SCS Site 10 Dam is classified as having a fair condition assessment. The dam features an uncontrolled spillway and outlet gates for water discharge management. The surrounding area has a drainage area of 24 square miles, with a maximum discharge capacity of 48,117 cubic feet per second. Despite its age, the dam continues to serve its purpose effectively and remains an important asset for flood control in the region.
Overall, the San Diego-Rosita Cks WS SCS Site 10 Dam plays a vital role in mitigating flood risks and protecting the surrounding community from potential water-related hazards. As climate change continues to impact weather patterns and increase the frequency of extreme events, the importance of well-maintained infrastructure like this dam cannot be overstated. With proper regulation, inspection, and maintenance, the dam stands ready to face future challenges and continue safeguarding the area from flooding.

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.
