Summary
Built in 1910, this private-owned earth dam serves as a vital water resource with a storage capacity of 130 acre-feet. Despite its age and historical significance, the dam's condition assessment has been rated as poor, indicating a need for maintenance and potential risk mitigation measures.
With a height of 14 feet and a length of 390 feet, Larry L Yonce Pond Dam plays a crucial role in regulating water flow and storage in the region. However, its poor condition and significant hazard potential highlight the importance of regular inspections and maintenance to ensure the safety and functionality of the dam. The dam's structural integrity and emergency action plan readiness are areas that require immediate attention to safeguard against any potential risks or incidents.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper maintenance and management of dams like Larry L Yonce Pond Dam to protect not only the local ecosystem but also the surrounding communities that rely on its water storage and regulation capabilities. By staying informed and engaged in the upkeep of vital infrastructure like dams, we can contribute to the sustainability and resilience of our water resources in the face of changing climates and environmental challenges.

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.
