Summary
This Earth-type dam stands at a height of 46 feet and stretches 860 feet in length, providing crucial flood risk reduction capabilities. With a storage capacity of 2,343 acre-feet, it plays a critical role in protecting the surrounding area from potential inundation during periods of heavy rainfall or storm events.
Maintained by the Department of Conservation and Recreation in Virginia, Marrowbone Creek Dam #1 is regularly inspected to ensure its structural integrity and overall condition. The dam has been assessed as being in fair condition, with a high hazard potential due to its proximity to the surrounding community. Despite its importance in flood risk reduction, the dam has not undergone significant modifications in recent years, highlighting the need for ongoing monitoring and maintenance to uphold its effectiveness in safeguarding the area against potential water-related disasters.
As a key component of water resource management in the region, Marrowbone Creek Dam #1 serves as a critical infrastructure asset in protecting against flood events along Marrowbone Creek. With its significant storage capacity and strategic location, the dam plays a crucial role in reducing the risk of inundation and ensuring the safety of local residents and properties. Ongoing inspection and maintenance efforts are essential to uphold the dam's functionality and effectiveness in mitigating flood risks in the area, underscoring the importance of continued investment in water resource infrastructure to safeguard against climate-related challenges.

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.
