Summary

This privately owned earth dam stands at a height of 11.5 feet and has a length of 900 feet, creating a reservoir with a storage capacity of 59.7 acre-feet. With a normal storage level of 20.26 acre-feet and a surface area of 7.9 acres, Walton Dam provides opportunities for water-based activities such as boating, fishing, and wildlife observation.

The dam's low hazard potential is complemented by its condition assessment of "Not Rated," indicating a stable and well-maintained structure. Although the dam does not have designated spillways or lock systems, it is designed to manage a maximum discharge of 545 cubic feet per second. Despite not being regulated by the state or federal agencies, Walton Dam's risk management measures and emergency action plans ensure the safety of surrounding communities in the event of a flood or other emergency situation.

In the absence of a designated inspection frequency or condition assessment date, Walton Dam continues to serve as a valuable asset for recreational enthusiasts and water resource managers alike. With its tranquil reservoir setting and low-risk profile, this privately owned earth dam stands as a testament to the importance of sustainable water management practices in the face of changing climate patterns.

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.
