Quick Summary

A study by the International St. Mary and Milk Rivers Study Board proposes building inflatable dams in Montana’s Glacier National Park to address agricultural water shortages. The dams would store about 5.4 billion gallons of water on St. Mary Lake, potentially improving water availability for farmers during dry periods. However, conservationists like Tyrel Fenner and representatives from the Blackfeet Nation are concerned about potential environmental damage and wildlife disruption. Glacier National Park officials were not involved in developing this plan.

Story summary

A proposed plan to build an inflatable dam in Glacier National Park, Montana, aims to address regional agricultural water shortages but faces opposition from conservationists and the Blackfeet Nation. The project would divert water from the International St. Mary River within the park's boundaries. Peter Metcalf, executive director of the Glacier-Two Medicine Alliance, expressed concern over potential harm to wildlife and the park’s natural beauty. Hydrologist Tyrel Fenner warned that animals like elk, moose, or bears could damage the dam, exacerbating rather than solving water scarcity issues for local farmers. The plan is part of a study published this summer but has yet to receive official approval due to these environmental concerns.
