Summary
Standing at a height of 10 feet with a length of 600 feet, this dam holds a maximum storage capacity of 176 acre-feet and a normal storage capacity of 88 acre-feet. The dam is situated on the TR-Ygnacio Creek and is regulated by the state with permitting and inspection requirements in place.
Despite its importance for water supply, the dam lacks a spillway and has been classified with a high risk assessment rating of 2. The condition of the dam is currently not rated, and there is limited information available regarding emergency action plans and risk management measures. With Vicente Gonzalez serving as the Congressional representative for the area, there is a need for increased oversight and maintenance to ensure the safety and reliability of the Duval County Ranch Lake No 2 Dam for the surrounding community and ecosystem.
Enthusiasts of water resources and climate in the region should keep a close eye on the Duval County Ranch Lake No 2 Dam, as its condition and risk assessment indicate potential vulnerabilities that could impact water supply and environmental integrity. Collaboration between local authorities, private owners, and regulatory agencies is essential to address any deficiencies in the dam's infrastructure and emergency preparedness, ultimately enhancing its resilience to future climate challenges and ensuring the safety of the surrounding area.

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.
