Summary

Built in 1967, this earth dam stands at a height of 45 feet and serves primarily for fire protection, stock, and as a small fish pond. With a storage capacity of 162 acre-feet and a surface area of 10 acres, Dramamine plays a crucial role in water resource management in the area.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Dramamine is regulated, permitted, inspected, and enforced by the state authorities. Despite being categorized as having low hazard potential and not currently rated for condition assessment, the dam continues to fulfill its intended purposes effectively. Situated on TR-Hay Creek, Dramamine provides essential water resources for the local community and plays a vital role in sustaining the ecosystem in the region.

Through its presence, Dramamine contributes to the overall water resource and climate resilience in Judith Basin, Montana. With its modest scale and specific purposes, this privately-owned dam serves as a valuable asset for fire protection, livestock management, and conservation efforts in the area. As climate enthusiasts and water resource advocates, understanding and appreciating the significance of structures like Dramamine is essential for promoting sustainable water management practices and ensuring the long-term viability of our natural resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
