Summary
Completed in 1944, this dam serves multiple purposes including fire protection, stock, and small fish pond. Situated on TR-COON CREEK, the dam has a height of 30 feet and a length of 200 feet, providing a storage capacity of 39 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Ehret #1 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular state inspection and enforcement.
This dam, managed by private owners, plays a crucial role in water resource management and climate resilience in the region. Its strategic location and primary purposes ensure the availability of water for fire protection, livestock, and recreational activities. Despite being constructed over 75 years ago, Ehret #1 continues to provide essential services to the local community and contributes to the overall water security in the area. With its low hazard potential and regulated status, the dam represents a reliable and safe water management infrastructure.
As water resource and climate enthusiasts, understanding the significance of structures like Ehret #1 is vital for recognizing the interconnectedness of water management, environmental stewardship, and community resilience. This dam serves as a testament to the importance of maintaining and regulating water infrastructure to ensure sustainable water usage and protection against potential hazards. With its historical significance and ongoing role in water resource management, Ehret #1 stands as a valuable asset in the region's efforts to adapt to changing climate conditions and secure access to essential water resources.

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.
