Summary

Standing at a height of 28 feet, it serves the purpose of water resource management with a storage capacity of 120 acre-feet. The dam is under the jurisdiction of the Department of Conservation and Recreation in Virginia, ensuring state regulation, inspection, and enforcement for its safety and maintenance.

Although the hazard potential of Longwalk Dam is classified as "undetermined" and its condition assessment is "not rated," the dam remains an essential infrastructure for water storage in the region. With its strategic location and design, the dam plays a crucial role in managing water resources and mitigating the impacts of climate change in the area. The dam's emergency action plan status, risk assessment, and management measures are currently unspecified, indicating a potential need for further evaluation and planning to enhance its resilience.

As enthusiasts of water resources and climate, Longwalk Dam offers a fascinating study in dam engineering and water management practices. Its association with the Norfolk District of the US Army Corps of Engineers and the oversight by the state regulatory agency demonstrate a collaborative effort to ensure the safety and functionality of the dam. With its precise geographical coordinates at 37.7147 latitude and -77.9965 longitude, Longwalk Dam stands as a testament to human ingenuity in harnessing and conserving water resources for the benefit of the community and the environment.

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.
