Summary
The dam stands at 14 feet in height and spans 290 feet in length, with a storage capacity of 52 acre-feet. Situated on TR-Whitetail Creek in Custer County, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring regular inspections and enforcement of safety measures.
Despite its low hazard potential, Hook #2 plays a crucial role in protecting the surrounding area from wildfires and providing water for livestock and recreational fishing. With its location in a picturesque setting within the Omaha District, the dam serves as an essential resource for the local community. While its condition is currently unrated, ongoing maintenance and regulatory oversight ensure the safety and functionality of this vital water infrastructure.
As a point of interest for water resource and climate enthusiasts, Hook #2 exemplifies the intersection of human infrastructure with natural water systems. Its design and purpose reflect the balance between human needs and environmental stewardship, highlighting the importance of responsible dam management in the face of changing climate conditions. This dam serves as a reminder of the interconnectedness of water resources, climate resilience, and community well-being in the rural landscapes of Montana.

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.
