...Middle Yukon River Breakup Status...



As of Friday afternoon, ice and water continues to flow past Galena, 

even though there is still some in-place ice slowing it down above 

Pilot Mountain Slough. There are a few more short in-place sections 

of ice between Galena and Nulato that should not cause any 

significant jamming concerns. Below Nulato, the river ice remains 

in-place with signs of lifting and thermal degradation. The Yukon is 

open from Galena upstream to the Nowitna River with the exception of 

a small (<1 mile) section of in-place ice at Big Eddy/Ham Island. 

From the Nowitna upstream to the Boneyard, there is thermally 

degrading in-place ice. The Yukon is open between Tanana and the 

Boneyard; however, ice runs can be expected when the breakup between 

Ft. Yukon and Rampart Canyon finally occurs. The River Watch team 

will fly again on Saturday morning.
