Summary

With a dam height of 15 feet and a length of 735 feet, this structure holds a normal storage capacity of 22 acre-feet and a maximum storage of 69 acre-feet. Situated on TR-Van Burton Creek, this low-hazard dam serves as a vital water resource for the surrounding area, providing essential functions for both human and ecological needs.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Hook #64 is regularly inspected, permitted, and enforced to ensure its structural integrity and safety. Despite being labeled as "Not Rated" in terms of condition assessment, this dam plays a crucial role in maintaining water supply and protection against potential fire hazards in the region. With its strategic location and purposeful design, Hook #64 stands as a testament to responsible water resource management in the face of a changing climate.

As climate enthusiasts and water resource advocates look to safeguard and enhance our natural infrastructure, Hook #64 serves as a prime example of how state agencies like the DNRC in Montana are prioritizing the maintenance and regulation of essential water structures. By understanding the importance of these dams for both human and environmental well-being, stakeholders can work together to ensure the continued sustainability and resilience of our water resources in the face of evolving climate challenges.

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.
