Alaska's capital of Juneau faced record floodwaters due to rainwater and snowmelt flowing downstream from a basin dammed by the Mendenhall Glacier.

One of Alaska's most populated cities is bracing for potentially catastrophic flooding as a basin dammed within the Mendenhall Glacier has started to release water.

Watery Mess Parts of Alaska's state capital of Juneau flooded earlier this week after a melting glacier near the city and sent icy waters down below to residents, according to The Guardian, and, yes,

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.

This year, a giant wall of reinforced sandbags erected with the help of the U.S. Army Corps of Engineers held back the worst of the flooding in Juneau, to residents' great relief.

Hood boarded a helicopter to investigate. Flying over the glaciers at the head of the Mendenhall River, he saw collapsed ice and stranded icebergs in a basin between the Mendenhall Glacier and one of its smaller tributaries, Suicide Glacier. That indicated water had just drained as a glacial dam released and caused the flood.

A powerful surge of glacial meltwater is once again testing Juneau's resilience, and this time, the ripple effects could reach well beyond city limits — impacting thousands of travelers headed to Alaska’s capital by cruise ship.
