Summary
Completed in 1960, this earth dam serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 14 feet and a length of 325 feet, the dam has a storage capacity of 127 acre-feet and a normal storage level of 24 acre-feet. It is regulated and inspected by the Montana Department of Natural Resources and Conservation (DNRC) to ensure compliance with state regulations.
Situated on the TR-Twelve Mile Creek, the Courtney Herefords #3 dam plays a crucial role in managing water resources in the region, especially for agricultural and fire protection purposes. Despite its low hazard potential and unassessed condition, the dam remains an essential infrastructure for the local community. As a part of the regulatory requirements, the dam is subject to state permitting, inspection, and enforcement to ensure its safety and functionality. With its location in a remote area and limited associated structures, the dam serves as a vital resource for water management and conservation efforts.
Managed by private owners, Courtney Herefords #3 represents a key component of the water infrastructure in the region, contributing to the sustainability of water resources and ecosystem health. With its historical significance dating back to the 1960s, the dam continues to provide valuable services for fire protection, livestock, and recreational uses. As climate change impacts water availability and quality, the proper regulation and maintenance of dams like Courtney Herefords #3 are crucial for ensuring water security and resilience in the face of evolving environmental challenges.

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.
