Summary
Managed by USBOR, this Fish and Wildlife Pond was completed in 1992 with a dam height of 11 feet and a storage capacity of 399 acre-feet. The reservoir covers an area of 100.2 acres and is regulated by the NDSWC, with state permitting, inspection, and enforcement in place.
The primary purpose of Arrowwood NWR is for fish and wildlife conservation, providing a habitat for various species in the region. The dam structure is made of earth and stone materials, equipped with a controlled spillway and a single vertical lift outlet gate. Despite being rated as low hazard potential and not currently assessed for condition, the reservoir poses a very high risk due to its location near the James River and surrounding areas.
Located in a beautiful natural setting and serving as a crucial resource for wildlife, Arrowwood NWR is a significant water management project in North Dakota. With its strategic design and state-regulated operations, this reservoir plays a vital role in supporting the local ecosystem and managing water resources effectively. Climate and water enthusiasts will find Arrowwood NWR to be an intriguing example of sustainable water management in action.

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.
