Summary
Built in 1960 for fire protection, stock, or as a small fish pond, this structure stands at 10 feet high and spans 300 feet in length. With a storage capacity of 222 acre-feet, Hybner serves a variety of purposes while being regulated by the Montana Department of Natural Resources and Conservation (DNRC). Despite its low hazard potential and a condition assessment of "Not Rated," the dam is equipped for state permitting, inspection, and enforcement, ensuring its safety and compliance with regulations.
The surrounding area, in Hill County, Montana, benefits from Hybner's presence for water resource management and wildlife support. Its location in Congressional District 00, represented by Greg Gianforte, contributes to local environmental conservation efforts. While the dam's condition assessment remains unrated, its storage capacity of 222 acre-feet provides valuable water resources for the region. With a focus on fire protection, stock, and small fish pond maintenance, Hybner plays a crucial role in sustaining the ecosystem along TR-Sage Creek.
Hybner, a key structure in the Omaha District, not only serves as a water resource for Gildford but also as a protective measure against potential hazards. While the dam has not been rated for condition assessment, its compliance with state regulations and regular inspections ensure its reliability. As a contributor to the local ecosystem and a vital resource for water management, Hybner stands as a crucial element in the conservation and sustainability efforts of the region.

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.
