Summary
Built in 1960, this earth dam stands at a height of 15 feet and has a storage capacity of 54 acre-feet. Situated on the Little Badger Creek, Wilma serves as a vital resource in the region with a low hazard potential and state-regulated operations, inspections, and enforcement.
Owned privately and falling under Congressional District 00, Montana, Wilma is a testament to the importance of water resource management in the area. With its proximity to the city of Poplar and the Omaha District, the dam plays a significant role in ensuring the safety and sustainability of the surrounding community. Despite being not rated in condition assessment, Wilma remains a key asset in the region's water infrastructure.
For water resource and climate enthusiasts, Wilma represents a fascinating case study in dam construction and management. With its historical significance and ongoing state jurisdiction, the dam serves as a reminder of the critical role that such structures play in safeguarding communities and supporting various water-related activities. As efforts continue to monitor and regulate Wilma, its presence remains a cornerstone in the sustainable development of the region's water resources.

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.
