Summary
Designed by the USDA NRCS, this earth dam stands at a height of 28 feet and has a primary purpose of fire protection, stock, or small fish pond. With a storage capacity of 62 acre-feet and a spillway width of 15 feet, Frog Dam serves as a vital resource for water management in the region.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Frog Dam is state-regulated and undergoes regular inspections and enforcement to ensure its safety and functionality. Despite its low hazard potential, the dam's condition assessment is currently not rated. Emergency preparedness measures, such as an Emergency Action Plan (EAP), have not been updated recently, highlighting the importance of maintaining and monitoring this essential water infrastructure.
With its picturesque location in Richland County and contribution to fire protection and ecological balance, Frog Dam stands as a testament to effective water resource management and conservation efforts in Montana. Climate and water enthusiasts can appreciate the harmonious coexistence of human development and environmental stewardship showcased by this modest yet significant structure along TR-Hardscrabble Creek.

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.
