Summary
The earth dam, standing at a height of 20 feet and completed in 1920, has a storage capacity of 79 acre-feet and is regulated by the Department of Natural Resources and Conservation (DNRC) in Montana. Situated on Warm Springs Creek, the lake serves as a crucial water resource for the surrounding area, with a low hazard potential and no current condition rating.
The dam at Plunket Lake spans 300 feet in length and has a maximum discharge capacity of 170 cubic feet per second. Despite its age, the reservoir remains a reliable water source for agricultural needs in the region. With state jurisdiction and regulatory oversight in place, including permitting, inspections, and enforcement, the dam at Plunket Lake is well-maintained and monitored to ensure the safety of its operations. For water resource and climate enthusiasts, Plunket Lake offers a fascinating example of historic water infrastructure supporting modern irrigation practices in Montana.
Overall, Plunket Lake represents a harmonious blend of historical significance and practical utility in water management. Its presence on Warm Springs Creek contributes to the local ecosystem and agricultural landscape, showcasing the importance of sustainable water resource development. As enthusiasts in the field of water resources and climate, exploring the story of Plunket Lake provides valuable insights into the intersection of human ingenuity, environmental stewardship, and the enduring relevance of water infrastructure in shaping communities and landscapes.

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.
