Summary
The dam stands at 18 feet high and stretches 275 feet in length, providing a storage capacity of 77 acre-feet. Situated on the TR-Hallanger Coulee, the dam is regulated by the state and falls under the jurisdiction of the Department of Natural Resources and Conservation (DNRC) in Montana.
Despite its age, Cherry Creek #11 has a low hazard potential and has not been rated for its condition assessment. The dam has not undergone recent inspections or maintenance, with no emergency action plan (EAP) in place. The risk assessment, risk management measures, and inundation maps for the dam are also not available. Its location in a rural area with minimal associated structures suggests limited risk to the surrounding community, but the lack of updated information raises concerns about the dam's long-term safety and stability.
Water resource and climate enthusiasts interested in Cherry Creek #11 may be intrigued by its historical significance and potential for ecological benefits. The dam's primary purposes of fire protection and water storage for stock and fish ponds highlight its importance in supporting local agriculture and wildlife. However, the absence of recent inspections and maintenance, coupled with the lack of emergency preparedness measures, underscore the need for continued monitoring and investment in dam safety to ensure its continued function and protection of downstream communities and ecosystems.

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.
