Summary
Completed in 1960, this Federal-owned dam primarily functions as a Fish and Wildlife Pond, supporting the conservation efforts of the Fish and Wildlife Service. With a dam height of 7 feet and a storage capacity of 239 acre-feet, the dam plays a crucial role in regulating water flow and providing habitat for various aquatic species.
The dam, designed by D. Fazzan and D. Wylie, is classified as an Earth dam with a controlled spillway type. Despite its fair condition assessment as of October 2020, the dam poses a low hazard potential and undergoes regular inspections by the Fish and Wildlife Service. In 2006, both hydraulic and structural modifications were made to enhance the dam's performance and longevity. With a risk assessment rating of Very High (1), the dam's risk management measures are continuously monitored to ensure the safety and integrity of the structure.
Tewaukon Pool 2a Dam stands as a testament to the intersection of water resource management and wildlife conservation efforts in North Dakota. Its role in maintaining a balanced ecosystem and providing essential habitat for diverse species underscores the importance of sustainable water infrastructure for both environmental and recreational purposes. As climate change continues to impact water resources, the management and maintenance of dams like Tewaukon Pool 2a play a crucial role in safeguarding our natural environment for future generations.

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.
