Officials say new barriers protected against the kind of major damage inflicted during last year’s destructive Suicide Basin release, though high water inundated numerous areas.

When the peak of the annual glacial outburst flood hit early Wednesday morning in Juneau, newly installed flood barriers stacked along the Mendenhall River largely prevented flooding of the nearby residential area.

A huge basin of rainwater and snowmelt dammed by Alaska’s Mendenhall Glacier has started to release, sending a potentially record surge of flooding toward parts of Juneau.
