Summary

Owned by the local government, this earth dam serves as a fish and wildlife pond with a storage capacity of 105 acre-feet. Despite its low hazard potential, the dam's condition is assessed as poor, with the last inspection conducted in 2009. It is regulated by the Department of Conservation and Recreation, ensuring that state permitting, inspection, and enforcement measures are in place to maintain its integrity.

The dam stands at a height of 6.5 feet and has a spillway type of uncontrolled, with a surface area of 0.05 acres and a drainage area of 1.66 square miles. While it serves a primary purpose of fish and wildlife preservation, its condition assessment indicates the need for potential maintenance or rehabilitation. With a moderate risk rating, stakeholders and environmental enthusiasts should stay informed about any future risk management measures or updates regarding the dam's structural integrity to ensure the safety of the surrounding ecosystem and community.

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.
