Summary
This earth dam stands at a height of 52 feet and spans 700 feet in length, providing a storage capacity of 544 acre-feet and serving a drainage area of 1.79 square miles. The dam, managed by the local government and regulated by the Department of Conservation and Recreation, plays a vital role in mitigating flood hazards in the region.
With a high hazard potential but a satisfactory condition assessment as of March 2020, Shoemaker River # 1a is a key component of the water resource infrastructure in the area. The dam, constructed for flood risk reduction purposes, has withstood the test of time with regular inspections and maintenance ensuring its continued effectiveness. The emergency action plan for the dam was last revised in July 2003, highlighting the ongoing commitment to safety and preparedness in the face of potential emergencies.
Enthusiasts of water resources and climate resilience will find Shoemaker River # 1a to be a fascinating example of infrastructure designed to protect communities from the impacts of flooding. As a state-regulated and inspected dam in Virginia, it represents a crucial asset in the local landscape, serving both practical and safety functions. The structure's history, design, and ongoing management offer valuable insights into the intersection of water management, environmental protection, and public safety in the face of changing climate conditions.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
