Summary
Built in 1965 by the USDA NRCS, this irrigation dam stands at a height of 18 feet and has a length of 550 feet. With a storage capacity of 55 acre-feet, it primarily serves the purpose of irrigation for the surrounding area.
Managed by the DNRC and regulated by the state of Montana, Shumaker #1 has a low hazard potential and is currently assessed as "Not Rated". While specific inspection and emergency preparedness details are not provided, the dam is classified as meeting state permitting, inspection, and enforcement requirements. Situated in a picturesque location, this dam is a crucial water resource for the local community and contributes to the overall water management efforts in the region.
Overall, Shumaker #1 is a vital piece of infrastructure that plays a significant role in supporting agricultural activities in the area. With its construction overseen by the Natural Resources Conservation Service, this earth dam continues to be an essential component of the water resource management system in Montana, ensuring a reliable water supply for irrigation purposes along the TR-Little Whitney Creek.

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.
