Summary
Built in 2002 by the NRCS, this earth dam stands at 7.2 feet high and has a storage capacity of 192.6 acre-feet. The dam serves a primary purpose of "Other" and is regulated by the NDSWC, with state permitting, inspection, and enforcement in place.
With a spillway width of 10 feet and a surface area of 9.15 acres, Graber Dam is classified as having an "Undetermined" hazard potential and has a moderate risk level of 3. While the condition of the dam has not been rated, it meets the state's regulatory guidelines and has not been modified since its completion. The dam does not have any outlet gates and is primarily constructed from stone and soil materials.
Although Graber Dam may not be widely known, its presence plays a crucial role in water resource management and climate resilience efforts in the region. Water resource and climate enthusiasts will appreciate the structure's design and functionality, as well as the collaborative efforts between private ownership and state regulatory agencies to ensure its safety and effectiveness in managing water flow and storage along the James River-OS.

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.
