Summary
The reservoir has a dam height of 11 feet and a storage capacity of 82 acre-feet, providing essential water for the surrounding area. Situated on East Fork Horse Creek, this reservoir plays a crucial role in maintaining water supply and supporting local wildlife habitats.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), East Fork Reservoir is inspected, regulated, and enforced by state authorities to ensure its structural integrity and compliance with safety standards. With a low hazard potential and a condition assessment of "Not Rated," the reservoir serves as a reliable water source for the community. Despite not being rated, the reservoir remains a key asset for fire protection, livestock watering, and recreational fishing in the region.
Surrounded by picturesque landscapes and offering a tranquil escape in Cartersville, East Fork Reservoir is a vital water resource in Montana. With its strategic location on East Fork Horse Creek and a storage capacity of 82 acre-feet, this reservoir supports various purposes while maintaining a low hazard potential. As a well-regulated and inspected water body, East Fork Reservoir stands as a testament to sustainable water management practices and serves as a valuable asset for the local community and ecosystem.

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.
