Summary
Built in 1950, this earthen dam stands at a height of 20 feet and spans 800 feet in length. With a storage capacity of 51 acre-feet, it primarily relies on the TR-East Fork Battle Creek for water supply.
Despite being categorized as having a low hazard potential, Thretening Times is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular state inspections and enforcement measures. The dam has not been rated for its current condition, and its emergency action plan (EAP) status, as well as risk management measures, remain unclear. Located within Congressional District 00 under the jurisdiction of the Omaha District of the US Army Corps of Engineers, Thretening Times presents a critical water resource in the region.
As climate change continues to impact water resources, enthusiasts and stakeholders should monitor the maintenance and assessment of dams like Thretening Times to ensure their safety and functionality. With the potential for extreme weather events and increased strain on water supplies, prioritizing the regulation and upkeep of critical infrastructure is essential for safeguarding communities and ecosystems in the face of threatening times.

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.
