Summary
Built in 1939, this earth dam stands at a height of 28 feet and serves primarily for fire protection, stock, and small fish pond purposes. With a storage capacity of 217 acre-feet, the reservoir is fed by Peoples Creek and covers a surface area ideal for its intended functions.
Despite being a low hazard potential structure with a condition assessment of 'Not Rated', Anderson Reservoir plays a crucial role in providing essential water resources for fire protection and livestock in the region. Its location in Blaine County, Montana, under the jurisdiction of DNRC, ensures regular inspections, permitting, and enforcement, guaranteeing the safety and efficiency of the dam. Water and climate enthusiasts will be fascinated by the historical significance and practical utility of this reservoir in sustaining local ecosystems and agricultural activities.
As part of the Omaha District of the US Army Corps of Engineers, Anderson Reservoir contributes to the overall water management infrastructure in the region. With a maximum storage capacity of 217 acre-feet and a normal storage level of 111 acre-feet, the reservoir remains a vital resource for the community. Climate enthusiasts will appreciate the role of this structure in maintaining water supply stability and supporting environmental conservation efforts in the area.

Dam Data Reference
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.
