A rush of glacial floodwater swept down Alaska’s Mendenhall River on Wednesday morning, prompting evacuation warnings in parts of Juneau.

For the third consecutive year, a wave of water gushed out of an Alaskan glacial lake, threatening the state’s capital city of Juneau. But, flood barriers installed by the city managed to prevent disaster from unfolding in the picturesque port town despite record-breaking water levels this week.

Mendenhall River crested at a record-setting 16.65 feet deep as of 7:15 a.m. Alaska time (12:15 Eastern), and began to empty, according to National Weather Service experts. The water level had fallen to about 8.

New sandbag-style barriers installed along a river in Alaska's capital city held back record levels of flooding and prevented widespread damage after an ice dam at the nearby Mendenhall Glacier released a massive amount of rainwater and snowmelt downstream,
