Late Friday morning... an observer reported that the three low water
crossings along The Spine Road continue to be inundated with water.
Water levels continue to slowly climb due to snowmelt and overflow
of inplace channel ice.

will be inundated with water. Spine Road will likely be closed to
constructions and maintenance crews.

... The Flood Advisory for melting snow and flooding related to
overflow of inplace channel ice remains in effect until 230 PM
akdt Saturday for the Colville river...

High water from melting snow runoff is causing flooding along the
Colville river near Colville Village. An ice jam upstream from
Colville Village was reported to release yesterday with a subsequent
ice jam reforming further downstream.

An ice jam was reported just upstream of Colville Village this morning.
Water levels at Colville Village rose overnight. The current
stage is 6.77 feet which is above moderate flood stage. Approximately
95 percent of the Colville Village Island..including the runway... is
flooded.

A further rise in flood waters is possible as ice jams release and
reform. No major ice movement has been observed in the Main Channel
adjacent to Colville Village.

Expected impacts: 95 percent of the Colville Island... including the
runway... is under water. The Colville Village Lodge could be
impacted if water levels continue to rise.

This flooding will remain over sparsely populated areas of central
central Beaufort Sea coast.
