Summary
Completed in 1959, this earth-type dam stands at a height of 30 feet and has a storage capacity of 189 acre-feet, with a normal storage level of 56 acre-feet. The dam spans 1000 feet along Lund Coulee, a tributary of the Missouri River, and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
Despite its low hazard potential and a current condition assessment of "Not Rated," the Kielman dam has not been inspected or assessed for emergency preparedness, such as the development of an emergency action plan (EAP) or inundation maps. The dam is not under the jurisdiction of any federal agency, and there are no associated federal funding or regulatory responsibilities. The dam's purpose is solely for irrigation, serving the agricultural needs of the surrounding area with its water storage capabilities.
As a vital component of the local water resource infrastructure, the Kielman dam plays a crucial role in supporting agricultural activities in the region. However, the lack of recent inspections and emergency preparedness measures highlight the importance of regular maintenance and monitoring to ensure the safety and reliability of the dam for both irrigation purposes and potential flood control needs in the future.

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.
