Summary
This private-owned earth dam stands at a height of 9 feet and stretches over a length of 1650 feet. With a storage capacity of 112 acre-feet and a surface area of 16.5 acres, the dam plays a crucial role in ensuring water availability in the region.
Despite being a non-federal dam, Kone Lake Dam is subject to state permitting and inspection requirements to ensure its safety and compliance with regulations. The dam poses a high risk, with a hazard potential of "Not Available" and a risk assessment rating of 2 on a scale of 1 to 4. While the condition assessment is not rated, the dam's emergency action plan status and risk management measures are also lacking information, highlighting potential areas for improvement in emergency preparedness.
With its location on the TR-Nueces River and the absence of a spillway, Kone Lake Dam serves as a vital water resource infrastructure in the region. As climate change impacts water availability and quality, the maintenance and monitoring of dams like Kone Lake become increasingly important to ensure sustainable water management practices for both current and future generations.

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.
