Newly installed river barriers held back record levels of flooding and prevented widespread damage in Alaska’s capital city on Wednesday, after an ice dam at the nearby Mendenhall Glacier released a huge surge of rainwater and snowmelt, officials said.
Water pooled on several streets and in some yards in Juneau after the Mendenhall River crested earlier in the day, and high water was expected to persist for hours. But many residents in the flood zone had evacuated before peak water levels, and there were no damage reports similar to the past two summers, when about 300 homes were flooded.
The temporary barriers “really have protected our community”, Juneau city manager Katie Koester told a news conference. “If it weren’t for them, we would have hundreds and hundreds of flooded homes.”
On Tuesday morning, authorities confirmed that water had started escaping the ice dam, with flooding expected into Wednesday. Some Juneau residents in the flood zone had already evacuated as officials intensified their warnings on Tuesday, saying: “Don’t wait, Evacuate TONIGHT.”
