Summary
Completed in 1967, this earth dam stands at a height of 18 feet and spans 200 feet in length, providing essential water storage for fire protection, livestock, and small fish pond purposes. With a maximum storage capacity of 98 acre-feet and a normal storage level of 46 acre-feet, this reservoir plays a crucial role in the local water management system.
The reservoir is regulated by the state of Montana through the Department of Natural Resources and Conservation (DNRC), ensuring proper inspection, permitting, and enforcement measures are in place to maintain its integrity and safety. With a low hazard potential and a moderate risk assessment rating, Mckeever Reservoir serves as a vital water source for the surrounding area, particularly during times of drought or emergency. Although the condition assessment is currently not rated, the reservoir continues to support the community's water needs while adhering to state regulations.
Located along TR-Snow Creek, Mckeever Reservoir serves as a key water source in the region, with a spillway width of 50 feet and a maximum discharge capacity of 250 cubic feet per second. Despite not being under the jurisdiction of the US Army Corps of Engineers, the reservoir's strategic location and storage capacity make it an essential asset for water resource and climate enthusiasts interested in sustainable water management practices in Montana.

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.
