Summary

The dam, constructed in 1961 by the USDA NRCS, stands at a height of 20 feet and has a storage capacity of 125 acre-feet. The primary purpose of the earth dam is irrigation, with a low hazard potential and a condition assessment that is currently not available.

Situated on Tr-Racetrack Creek, Bowman Lake 2 is managed by the Natural Resources Conservation Service and regulated by the Forest Service. With a maximum discharge of 51 cubic feet per second, the reservoir provides essential water resources for agricultural activities in the region. Although the inspection frequency and condition assessment are not specified, the dam's emergency action plan status, risk assessment, and inundation maps are all marked as not available.

Despite limited information on the dam's current condition and emergency preparedness, Bowman Lake 2 serves as a vital water resource for irrigation purposes in the area. Water and climate enthusiasts interested in the management and sustainability of water resources in Montana may find this reservoir an intriguing subject for further investigation and exploration.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
