Summary
The dam stands at a height of 17 feet and spans a length of 320 feet, providing a storage capacity of 58 acre-feet. Situated on TR-Trail Creek, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by the state regulatory agency.
With a low hazard potential and a condition assessment of 'Not Rated', Hook #8 serves as a vital resource for the surrounding area, offering essential water storage for fire protection and livestock. The dam's location in Kinsey, Montana, under the jurisdiction of the DNRC, ensures that it meets state regulations and inspection standards. Despite its age, the dam remains a crucial asset for water resource management in the region.
As climate change continues to impact water resources, the importance of maintaining and regulating structures like Hook #8 becomes increasingly vital. With its strategic location and low hazard potential, the dam plays a key role in preserving water security and supporting various purposes such as fire protection and livestock management. As enthusiasts in water resource and climate management, understanding the significance of dams like Hook #8 is crucial for sustainable water management practices in the face of changing environmental conditions.

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.
