Summary
Completed in 1961, this earth dam stands at a height of 31 feet and spans a length of 5400 feet, providing a storage capacity of 7630 acre-feet. With a primary purpose of flood risk reduction, this dam plays a significant role in protecting the local community from potential disasters associated with heavy rainfall and storm events.
Managed by the TCEQ and regulated by the state of Texas, the San Diego-Rosita Cks WS SCS Site 2 Dam is equipped with a spillway width of 353 feet and outlet gates including slide (sluice gate) and uncontrolled mechanisms. The dam's inspection frequency is set at 5 years, with the last assessment conducted in March 2011. While the hazard potential and condition assessment are currently not available, the risk assessment for this structure is deemed moderate (3), indicating a certain level of vulnerability that necessitates ongoing monitoring and management measures by the responsible authorities.
As a vital component of the local water resource infrastructure, the San Diego-Rosita Cks WS SCS Site 2 Dam serves as a critical safeguard against flooding events in the area. Its strategic location along the San Diego Creek, coupled with its design and operational features, highlights the importance of this structure in protecting lives and properties from the impacts of extreme weather conditions. With a history dating back to the early 1960s, this dam continues to play a pivotal role in water management and disaster risk reduction efforts in Duval County, Texas.

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.
