Residents of Montana's largest city are warned water supply could run out in 36 HOURS

A red gantry that allows treatment plant staff to access the main building is plainly destroyed by the water

Officials stressed that the water is safe to drink, but that supplies are limited

The Yellowstone River was flowing at a historically high level of 16 feet as it roared past Billings

thanks to heavy weekend rains and melting mountain snow

Raging waters that flooded Yellowstone National Park and nearby communities earlier this week

made their way through Montana's largest city

destroying farms and ranches and forced the closure of its treatment plant, according to video

The city obtains its water from the river, and its treatment facility

was forced to close at 9:30 a.m. because it couldn't work effectively with the water levels.
