Summary
Completed in 1940, the reservoir serves multiple purposes, including fire protection, stock watering, and small fish pond maintenance. With a dam height of 18 feet and a storage capacity of 103 acre-feet, the reservoir provides essential water storage for the community of CARTERSVILLE and surrounding areas.
The reservoir, situated on the NORTH PRONG HAY CREEK, has a low hazard potential and is not currently rated for its condition. Despite this, the DNRC conducts regular inspections and enforces strict regulatory measures to ensure the safety and functionality of the structure. With a maximum storage capacity of 103 acre-feet and a normal storage level of 59 acre-feet, Hay Creek Reservoir plays a crucial role in water management and conservation efforts in Rosebud County, Montana.
For water resource and climate enthusiasts, Hay Creek Reservoir offers a fascinating glimpse into the intersection of human infrastructure and natural ecosystems. As a vital source of water for fire protection and livestock needs, the reservoir highlights the importance of sustainable water management practices in the face of a changing climate. With its history dating back to the early 1940s, this earth dam structure continues to provide essential services to the community while serving as a reminder of the delicate balance between human development and environmental stewardship.

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.
