Summary

Completed in 1983, this earth dam stands at a height of 12 feet and has a hydraulic height of 9.8 feet, serving primarily for recreational purposes. With a storage capacity of 182 acre-feet and a surface area of 15 acres, it provides a tranquil setting for visitors to enjoy the surrounding natural environment.

The dam, constructed by the US Navy, is classified as having a low hazard potential and fair condition assessment, with the last inspection conducted in March 2017. The spillway of the dam is uncontrolled and has a width of 24 feet, while the maximum discharge rate is 89 cubic feet per second. The risk assessment for Hideaway Pond Dam is moderate, indicating a need for ongoing monitoring and management measures to ensure its continued safety and functionality for the community.

Situated on the TR-Gambo Creek, Hideaway Pond Dam is a key feature within the Norfolk District of the US Army Corps of Engineers. Despite its low hazard potential, the dam plays an important role in providing recreational opportunities and maintaining the ecological balance of the surrounding area. Climate and water resource enthusiasts can appreciate the significance of this structure in both its environmental and recreational capacities within the Dahlgrin Naval Reservation.

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.
