Summary
Built in 1993 by the USFWS and DU, this Earth-type dam serves as a Fish and Wildlife Pond along Timber Creek. With a height of 15 feet and a storage capacity of 375 acre-feet, the dam covers a surface area of 39.3 acres and has a drainage area of 101.6 acres.
Managed by the NDSWC, Bohnet Dam is regulated and permitted by the state of North Dakota for inspection and enforcement. The dam features a Controlled spillway with a width of 150 feet and a vertical lift outlet gate. Despite being classified as Low hazard potential, the dam has a very high risk assessment rating of 1, though its condition assessment is not rated.
The presence of Bohnet Dam underscores the importance of water resource management for fish and wildlife conservation in the region. As climate change continues to impact water availability and quality, the upkeep and regulation of dams like Bohnet are crucial for safeguarding ecosystems and biodiversity. With its strategic location and purpose, Bohnet Dam stands as a testament to the collaborative efforts between private entities and state agencies in ensuring sustainable water management practices.

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.
