Summary
Built in 1960 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 17 feet and a storage capacity of 89 acre-feet, Karen #5 has a low hazard potential and is classified as having a moderate risk level.
Although the dam is not currently rated for its condition, it is regulated, permitted, inspected, and enforced by the Montana Department of Natural Resources and Conservation (DNRC). The spillway of Karen #5 is uncontrolled with a width of 30 feet, and it has a maximum discharge capacity of 150 cubic feet per second. The risk assessment for this dam indicates a moderate risk level, and there are currently no emergency action plans in place.
Water resource and climate enthusiasts will be intrigued by the data on Karen #5, particularly its historical background, structural features, and risk assessment. As a vital structure for fire protection and water storage in the region, Karen #5 highlights the importance of proper dam management and emergency preparedness. Further research and monitoring of this dam could provide valuable insights into its long-term sustainability and resilience in the face of changing climate conditions.

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.
