Summary
Built in 1944 by the USDA NRCS, this dam has a height of 12 feet and a length of 100 feet, with a storage capacity of 70 acre-feet. Situated on Lisk Creek in McCone County, Wackle serves as a key resource in the area, with a low hazard potential and a state-regulated status under the DNRC.
With a drainage area of 15.31 square miles and the ability to discharge up to 300 cubic feet per second, Wackle plays a crucial role in managing water resources in the region. Despite its age, the dam's condition assessment remains unrated, highlighting the need for ongoing inspections and maintenance to ensure its continued functionality. As a significant structure in the Omaha District, Wackle's presence underscores the importance of sustainable water management practices in the face of changing climate conditions.
Water resource and climate enthusiasts will find Wackle to be a fascinating example of human intervention in natural water systems. As a part of the broader network of dams and reservoirs in Montana, Wackle contributes to water security and ecosystem preservation in the region. Its location, design, and purpose reflect a balance between human needs and environmental stewardship, making it a site of interest for those passionate about sustainable water resource management and climate adaptation strategies.

Dam Data Reference
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.
