Summary
Built in 1958, this earth dam stands at a height of 15 feet and has a storage capacity of 155 acre-feet. Situated on TR-Twelvemile Creek, Korneman serves as a crucial water resource for the surrounding area, with a low hazard potential and a condition assessment that is currently not rated.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Korneman is subject to state regulation, permitting, inspection, and enforcement. Its location in Capitol, Montana, within Congressional District 00, is represented by Greg Gianforte (R). With a maximum discharge capacity of 800 cubic feet per second, Korneman plays a vital role in providing fire protection and water supply for the local community. Despite its importance, the dam has not been assessed for emergency preparedness or risk management measures.
Water resource and climate enthusiasts will find Korneman to be an intriguing case study of a private dam in Montana that serves multiple purposes, including fire protection and stock watering. With its historical significance dating back to 1958, Korneman's role in managing water resources on TR-Twelvemile Creek highlights the importance of proper regulation and maintenance to ensure the safety and sustainability of such structures. The dam's low hazard potential underscores the need for ongoing monitoring and assessment to mitigate potential risks and ensure its continued functionality for the community it serves.

Dam Data Reference
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.
