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.
