Summary
With a dam height of 20 feet and a length of 400 feet, Moncarpic has a storage capacity of 72 acre-feet and serves a drainage area of 1.56 square miles. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state permitting, inspection, and enforcement.
Despite being classified as having a low hazard potential and a condition assessment of "Not Rated," Moncarpic does not have an Emergency Action Plan (EAP) in place. The dam's spillway width is 50 feet, with a maximum discharge capacity of 220 cubic feet per second. The structure has not been modified in recent years and is not managed by the US Army Corps of Engineers. While the dam's risk assessment, hazard potential, and emergency preparedness require further evaluation, Moncarpic remains a vital resource for water management and conservation in the region.
Water resource and climate enthusiasts interested in Moncarpic can explore its historical significance, design features, and operational characteristics. The dam's location in the Omaha District, under Congressional District 00 of Montana, highlights its importance for local water supply, irrigation, and wildlife habitat. As a key infrastructure for fire protection and stock watering, Moncarpic stands as a testament to the ongoing efforts to sustainably manage water resources amidst changing climatic conditions in Montana.

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.
