...Yukon River breakup status...



The Yukon River is open from Tanana to downstream of Mountain 

Village as of Wednesday afternoon.  Near Emmonak and Alakanuk the 

river ice is lifted and thermally degraded and water levels are low. 

Ice runs from upstream of Tanana continue as ice degrades between 

Beaver and Rampart and heavy ice runs are still being seen along 

many reaches of the Yukon. Water levels remain low and no flooding 

is anticipated. Updates from today's River Watch flights will be 

available this eve.

The Koyukuk River is mostly open between Hughes and its confluence 

with the Yukon River.  Upstream of Hughes, short sections of 

in-place ice remain and will continue sending runs of ice downstream 

as breakup progresses.
