Summary
Standing at a height of 19 feet and a length of 1320 feet, this dam has a storage capacity of 365 acre-feet and covers a surface area of 29 acres. Despite its high hazard potential and a risk assessment rating of 2, the dam's condition assessment remains unrated, highlighting the need for regular inspections and maintenance to ensure its structural integrity and safety.
Managed by private owners, Jones & Flores Lake Dam overlooks the TR-ARROYO BOLENO river/stream and falls under the jurisdiction of the Galveston District in Texas. This dam does not have a spillway and features no locks, but is equipped with a single outlet gate. While the dam has not been inspected recently and lacks an emergency action plan, its critical importance for water resource management and environmental conservation necessitates proactive risk management measures and adherence to regulatory guidelines to mitigate potential hazards and ensure the protection of surrounding communities and ecosystems.
For water resource and climate enthusiasts, Jones & Flores Lake Dam serves as a significant infrastructure for local water supply, irrigation, and ecological conservation efforts. Its historical significance as a fire protection and stock pond facility underscores the importance of sustainable water management practices in safeguarding natural resources and supporting community resilience in the face of changing climate patterns. As discussions around water security and climate adaptation continue to gain momentum, the maintenance and monitoring of dams like Jones & Flores Lake Dam play a crucial role in ensuring sustainable water resource management and enhancing the overall resilience of water infrastructure systems in Texas and beyond.

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.
