Summary
Constructed in 1950, this earth dam stands at a height of 15 feet and has a storage capacity of 711 acre-feet, primarily used for irrigation purposes. The dam spans 450 feet in length and is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring compliance with state permitting, inspection, and enforcement requirements.
Situated in Hill County, Montana, Magnum East is categorized as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam has not been modified in recent years, it is subject to regular state inspections and meets state regulatory guidelines. Although there is no designated emergency action plan in place, the dam's operational status is closely monitored to mitigate any potential risks associated with its structural integrity. For water resource and climate enthusiasts, Magnum East presents an intriguing case study in private dam management and regulatory oversight within the state of Montana.
With a rich history dating back to the mid-20th century, Magnum East serves as a crucial water management infrastructure for the surrounding agricultural community. As a key component of the irrigation system in the area, this dam plays a vital role in ensuring water supply for crop cultivation and livestock operations. The dam's location within Congressional District 00, Montana, under the representation of Greg Gianforte (R), underscores the importance of water resource management in a region characterized by diverse environmental and climatic conditions.

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.
