Summary
Built in 2003 by USFWS, this earth dam stands at a height of 12.2 meters and has a storage capacity of 110.6 million gallons. Its primary purposes include fire protection and serving as a stock or small fish pond.
Despite being classified as having a low hazard potential, Syminow Dam is regulated by the North Dakota State Water Commission, with regular inspections and enforcement measures in place to ensure its safety. The dam features an uncontrolled spillway with a width of 60 feet and a vertical lift outlet gate. Although the condition assessment is currently not rated, the risk assessment for this structure is moderate.
Overall, Syminow Dam serves as a vital resource for water management and ecosystem support in the region. With its strategic location and design, it plays a crucial role in mitigating flood risks, providing water for firefighting purposes, and supporting local wildlife populations. Climate and water resource enthusiasts can appreciate the significance of this dam in maintaining a balance between human needs and environmental conservation efforts.

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.
