Summary
Standing at a height of 3.6 meters and with a length of 1315 meters, this earth dam serves as a key structure for water resource management in the region. With a storage capacity of 8450 acre-feet and a spillway width of 100 meters, Arrowwood Dam plays a vital role in flood control and water supply for the surrounding areas.
Despite being classified as a low hazard potential structure, Arrowwood Dam is subject to regular inspections and maintenance to ensure its structural integrity and safety. With a risk assessment rating of moderate, the dam is equipped with slide gates for water release and emergency protocols in place, although its condition is currently not rated. The dam serves as a crucial asset for climate resilience in the region, providing essential water management capabilities to address the challenges posed by a changing climate and increasing water demand.
As a part of the St. Paul District of the USACE, Arrowwood Dam highlights the importance of sustainable water resource management and the role of infrastructure in adapting to climate variability. With its strategic location on the James River and its capacity for flood control and water storage, Arrowwood Dam stands as a symbol of resilience in the face of climate challenges. As water resource and climate enthusiasts, understanding and supporting structures like Arrowwood Dam is essential for promoting sustainable water management practices and building climate resilience for the future.

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.
