Summary

Built in 1937, this Earth dam stands at 15 feet high and has a storage capacity of 188 acre-feet. With a normal storage level of 94 acre-feet, the lake covers a surface area of 24 acres and has a drainage area of 0.9 square miles. Kruger Lake is fed by Kruger Creek and has a maximum discharge of 480 cubic feet per second.

Despite its low hazard potential, the dam at Kruger Lake is in poor condition as of the last inspection in August 2018. The spillway is uncontrolled, with a width of 20 feet, and outlet gates are also uncontrolled. The risk assessment for the dam is moderate, with a risk level of 3. With its location just 17 miles from Belle Fourche, Kruger Lake serves as a vital resource for the surrounding area, providing water for irrigation, fire protection, and stock, as well as serving as a small fish pond. Climate enthusiasts and water resource experts alike would find Kruger Lake to be a fascinating case study in dam infrastructure and management.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
