Summary

Completed in 1979, this private-owned Earth type dam stands at 12 feet tall and stretches over 953 feet in length. With a normal storage capacity of 100 acre-feet and a maximum storage of 145 acre-feet, the dam plays a crucial role in managing water resources for the community.

The dam's controlled spillway, 20 feet wide, ensures efficient water release during high flow periods while maintaining safety standards. Despite its low hazard potential and satisfactory condition assessment, the risk assessment categorizes Hoover Pond Dam with a very high risk level (1). With state regulations in place for inspection, enforcement, and permitting, the dam is subject to regular monitoring to ensure its structural integrity and safe operation.

Situated in a picturesque setting near Gwinn, Hoover Pond Dam represents an essential infrastructure for water management in the area. As climate change impacts water resources, the continued maintenance and oversight of dams like Hoover Pond become increasingly important to safeguard against potential risks and ensure sustainable water supply for future generations.

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.
