Summary
Completed in 1964, this earth dam stands at a height of 18 feet and has a storage capacity of 216 acre-feet. The dam spans 200 feet in length and is situated on the Spring Creek, with a drainage area of 6.25 square miles.
Managed by the DNRC, the Spring Creek Irrigation project is regulated and inspected by the state of Montana. With a low hazard potential and a condition assessment that is currently not rated, this vital water resource infrastructure provides water for agricultural irrigation in the region. Although the dam's emergency action plan status and risk assessment details are not provided, its location in Mosby highlights its importance in supporting local agriculture.
With its primary purpose being irrigation, the Spring Creek Irrigation project plays a crucial role in sustaining agricultural activities in the area. Despite lacking certain details such as inspection frequency and emergency preparedness, this structure continues to serve its intended function effectively. For water resource and climate enthusiasts, the Spring Creek Irrigation project offers a glimpse into the intricate network of infrastructure that supports sustainable water management in Montana.

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.
