Summary

This earth dam with a buttress core stands at a height of 11 feet and spans 1650 feet in length, creating a storage capacity of 79 acre-feet. Despite having a high hazard potential, the dam is currently not rated for its condition assessment.

Situated on TR-Bonito Creek, the Javelina Tank Dam does not have a spillway and is equipped with one outlet gate. While it is not under state jurisdiction or regulation, the dam does undergo regular state inspections and permitting. The risk assessment for this structure has been classified as high, signifying the importance of implementing risk management measures in the future to ensure the safety and integrity of the dam.

Water resource and climate enthusiasts will find the Javelina Tank Dam an intriguing structure to study, given its unique design characteristics and storage capacity. As climate change continues to impact water resources, understanding the condition and risk associated with dams like Javelina Tank becomes increasingly crucial for effective management and adaptation strategies in the face of evolving environmental challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
