Summary

Built in 1959 by the USDA NRCS, this Earth-type dam stands at a height of 25 feet and has a length of 350 feet. It serves the primary purpose of irrigation, with a storage capacity of 344 acre-feet and a drainage area of 8.78 square miles.

Managed by the DNRC in Montana, German #9 is classified as having a low hazard potential and is currently in "Not Rated" condition. The dam has state jurisdiction and regulatory oversight, with permitting, inspection, and enforcement carried out by the appropriate agencies. Although specific details on maintenance and emergency preparedness are not provided, the dam's location in an area with a maximum discharge of 250 cubic feet per second highlights its importance in water resource management.

Overall, German #9 is a key infrastructure for irrigation in the region, providing valuable water storage and distribution capabilities. Its construction by the USDA NRCS and ongoing regulation by the DNRC ensure that it continues to support agricultural activities while maintaining safety standards for the surrounding community. As climate change impacts water resources, dams like German #9 play a crucial role in adapting to changing conditions and ensuring sustainable water management practices.

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.
