Summary
With a height of 37 feet and a length of 4150 feet, this earth dam serves as a vital barrier against potential flooding in the area. Owned and regulated by the local government and TCEQ, this dam has a storage capacity of 9108 acre-feet, with a normal storage level of 200 acre-feet.
Despite not having a spillway, the San Diego-Rosita Cks WS SCS Site 4 Dam is equipped with one slide gate for outlet control. The dam's risk assessment categorizes it as having a high risk level (2), underscoring its importance in mitigating flood hazards in the region. While the dam's condition is currently not rated, it undergoes regular state inspections and enforcement measures to ensure its structural integrity and operational efficiency.
For water resource and climate enthusiasts in the area, the San Diego-Rosita Cks WS SCS Site 4 Dam stands as a testament to effective flood risk reduction infrastructure. With its strategic location along TR-San Diego Creek and its significant storage capacity, this earth dam plays a vital role in safeguarding the surrounding communities from potential inundation events. As efforts continue to maintain and monitor the dam's condition, its critical importance in water resource management and climate resilience remains paramount.

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.
