Summary
Completed in 1936, this structure serves multiple purposes including fire protection, stock watering, and a small fish pond. With a dam height of 12 feet and a length of 300 feet, it provides a storage capacity of 89 acre-feet, with a normal storage level of 26 acre-feet.
Situated on TR-Elk Creek, J King #2 is regulated by the Montana Department of Natural Resources and Conservation (DNRC). Despite being classified as having a low hazard potential, the dam's condition has not been officially rated. The property falls under the jurisdiction of Congressional District 00 and is overseen by Representative Greg Gianforte. While there have been no recent inspections or assessments conducted on the dam, it is important for water resource and climate enthusiasts to stay informed about its condition and potential risks.
With no emergency action plan (EAP) in place and limited information on risk assessments or management measures, there is a need for increased monitoring and evaluation of J King #2. As climate change continues to impact water resources and infrastructure, it is crucial to ensure the safety and integrity of dams like this one to prevent potential hazards and protect surrounding communities. Stay tuned for updates on the condition and management of J King #2 as efforts are made to enhance its resilience and emergency preparedness.

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.
