Summary
With a dam height of 23.7 feet and a maximum storage capacity of 86 acre-feet, this earth dam plays a vital role in providing fish and wildlife habitat while also offering recreational opportunities to the local community. The dam is under the jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC) and is regulated, inspected, and enforced by the state.
Despite being rated as low hazard potential, Hollecker poses a high risk due to its condition assessment not being rated and lacking detailed risk management measures. The dam has not been inspected since May 2003, highlighting the need for regular monitoring and maintenance to ensure its structural integrity and safety. With its scenic location and importance for fish and wildlife conservation, it is crucial that Hollecker receives the necessary attention and resources to mitigate any potential risks and ensure its long-term functionality for both recreational and environmental purposes.
As water resource and climate enthusiasts, it is imperative to advocate for the proper management and maintenance of dams like Hollecker to safeguard their integrity and ensure the safety of nearby communities and ecosystems. By prioritizing regular inspections, risk assessments, and the implementation of effective risk management measures, we can help preserve these vital structures for future generations while also promoting sustainable water resource management practices in Montana and beyond.

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.
