Summary
With a height and hydraulic height of 20 feet, the dam has a storage capacity of 73 acre-feet, with a normal storage level of 64 acre-feet. The structure spans 200 feet in length and sits along the TR-Hay Creek, under the jurisdiction of the State of Montana and regulated by the DNRC.
This low hazard potential dam has not been rated for condition assessment, and there is limited information available regarding its inspection history and emergency preparedness. Despite these gaps, Gearhart #11 serves as a vital resource for water management in the region. The dam's strategic location and multi-purpose design make it a valuable asset for fire protection, livestock watering, and recreational use, highlighting the importance of maintaining and monitoring its structural integrity.
As water resource and climate enthusiasts continue to advocate for sustainable management of dams and reservoirs, Gearhart #11 presents an opportunity for further research and assessment. With its historical significance and functional versatility, this earth dam serves as a reminder of the interconnectedness between water infrastructure, environmental stewardship, and community resilience in the face of changing climate patterns.

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.
