Summary
Built in 1998 by the USFWS, this Earth-type dam serves as a Fish and Wildlife Pond along Dayton Creek. With a height of 11.8 feet and a length of 660 feet, the dam provides a storage capacity of 210.9 acre-feet and covers a surface area of 26 acres.
The dam's spillway, which is uncontrolled, has a width of 200 feet and the structure is regulated by the North Dakota State Water Commission. Despite being rated as having a low hazard potential, the dam is considered to have a moderate risk level. It has not been assessed for condition, and there is no Emergency Action Plan in place, indicating a need for further evaluation and planning to ensure the safety and integrity of the structure for the surrounding community and ecosystem.
Overall, Wallace Dam plays an essential role in supporting fish and wildlife in the area, but ongoing monitoring and management are necessary to address potential risks and ensure the continued effectiveness of the structure in the face of changing climate conditions and water resource management needs.

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.
