Summary
Managed by the Department of Conservation and Recreation, this dam serves primarily for irrigation purposes along the TR-HATCHER RUN river or stream. Standing at a height of 17 feet with a storage capacity of 185 acre-feet, Clarkes Dam plays a crucial role in water management in the region.
Although the hazard potential of Clarkes Dam is currently undetermined and its condition has not been rated, the dam undergoes regular inspections with a frequency of 1 year. Despite lacking a detailed risk assessment or emergency action plan, Clarkes Dam remains a vital structure for water supply and recreational activities in the area. With its earth dam type and location within the Norfolk District, this dam stands as a testament to the importance of water resource management in Virginia.
As water resource and climate enthusiasts, understanding the significance of Clarkes Dam in the broader context of water infrastructure and regulation can provide valuable insights into the challenges and opportunities in sustainable water management. With its alignment with state regulations and purpose for irrigation, Clarkes Dam exemplifies the intersection of human intervention and natural resources, highlighting the delicate balance required for effective water resource stewardship in the face of changing climate conditions.

Dam Data Reference
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.
