Summary
Completed in 1960, this earth dam stands at a height of 10 feet and stretches over 1400 feet in length, creating a fish and wildlife pond with a storage capacity of 957 acre-feet. The dam serves as a vital resource for the conservation of local flora and fauna, with a primary purpose of maintaining a habitat for various species.
Despite its low hazard potential and fair condition assessment, Tewaukon Pool 8 Dam is subject to regular state inspections and enforcement by the North Dakota State Water Commission. The dam features a controlled spillway with a width of 84 feet and other controlled outlet gates. With a maximum discharge capacity of 448 cubic feet per second, the dam plays a crucial role in managing water flow and maintaining the ecological balance in the surrounding area. The risk assessment for the dam is rated as very high, indicating the importance of robust risk management measures and emergency preparedness.
Overall, Tewaukon Pool 8 Dam stands as a testament to the collaboration between federal agencies and local authorities in safeguarding water resources and supporting wildlife conservation efforts. As a key feature in the Omaha District, this dam serves as a model for sustainable water management practices in the region, highlighting the critical role of infrastructure in preserving the natural environment amidst changing climate conditions.

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.
