A flood warning is in effect until 10 a.m. Friday for Juneau's Mendenhall Lake and surrounding areas.

Mendenhall Lake has reached moderate flood stage as of midday Thursday, and is still on track to crest near 12 feet late Thursday. This would be near record levels with flooding likely on Skaters Cabin Road, West Glacier Trailhead, Mendenhall Lake Campground, View Drive and homes in the area.

Water from Suicide Basin is draining into the lake forcing its level to rise.

Once the lake peaks early Friday, forecasters are expecting it to drop below minor flood stage by Friday afternoon. 

A similar event happened in July of 2016 when the lake rose to a record level of 11.99 feet

Here are the potential impacts:

  • At 9.1 feet: Water would cover Skaters Cabin and West Glacier Trailhead and would move into Mendenhall Lake Campground.
  • At 10.9 feet: View Drive would become flooded and impassable. Area homes would begin to see significant flooding.

Hydrologists, geologists and meteorologists are in Juneau closely monitoring the situation. Stay tuned to the KTVA Weather Team for the latest from Juneau.
