Summary
Built in 1900, this earth dam stands at 15 feet high and spans 200 feet in length, with a storage capacity of 69 acre-feet. Situated along the TR-Marias River, the reservoir is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring compliance with state permitting, inspection, and enforcement requirements.
With a low hazard potential and a current condition assessment of "Not Rated," German Reservoir serves as a vital resource for the local community in Loma, Montana. Although specific details about surface area, drainage, and maximum discharge are not available, the reservoir's normal storage capacity is reported to be 36 acre-feet. Its location in Congressional District 00, Montana, under the purview of Representative Greg Gianforte (R), underscores the importance of maintaining and managing this essential water infrastructure for water resource and climate enthusiasts in the region.
As a key component of the water management system in Toole County, German Reservoir plays a crucial role in ensuring water availability for firefighting, agricultural activities, and wildlife conservation. While the reservoir's emergency action plan, risk assessment, and inundation maps may need further development, its strategic placement and design demonstrate a commitment to sustainable water resource management. With ongoing monitoring and adherence to regulatory guidelines, German Reservoir continues to be a valuable asset for the community, offering a reliable water source for various needs while maintaining a low risk profile for potential hazards.

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.
