Summary
Constructed in 1993 by the USFWS, this earth dam stands at a height of 8 feet, with a length of 383 feet, and a storage capacity of 51.1 acre-feet. Situated on Indian Creek in Hettinger County, North Dakota, this dam not only provides critical habitat for local wildlife but also helps manage water resources in the area.
With a low hazard potential and a moderate risk assessment, Krogh Dam is a well-maintained structure under the jurisdiction of the NDSWC. The dam features an uncontrolled spillway with a width of 50 feet, and while it has not been rated for its condition, it continues to fulfill its primary purpose effectively. The surrounding area boasts a surface area of 6.3 acres and a drainage area of 3.43 square miles, making it a valuable asset for water resource management and climate resilience efforts in the region.
While Krogh Dam may not have a high profile, its importance in supporting local wildlife and managing water resources cannot be understated. With its strategic location on Indian Creek and its role as a Fish and Wildlife Pond, this dam stands as a testament to the importance of sustainable water management practices in North Dakota. As climate change continues to impact the region, structures like Krogh Dam will play a crucial role in safeguarding ecosystems and ensuring water security for future generations.

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.
