An ice jam above the mouth of the Fortymile River has remained in 
place since Thursday.  With the cooler temperatures snowmelt 
contribution to the Yukon has not increased water levels at Dawson 
so this jam has been stable and will likely erode from the 
downstream side.  In this scenario, Eagle and other locations along 
the Yukon that currently have open water can expect eventual ice 
runs accompanied by a significant rise in water levels as this jam 
releases and potentially adds to the current jam downstream of 
Calico Bluff.
