River Watch flew the Yukon River on Tuesday from Eagle to the Fortymile River. An observer 23 miles upstream of Eagle said that the Yukon River there broke up Monday afternoon. Ice began flowing but within a few hours had stopped flowing and an ice jam formed. Yukon rose to near mid-summer high levels and was continuing to rise slowly. Due to current river levels and ice conditions, the threat for flooding has diminished in the area around Eagle. However, ice jams can still pose a localized threat in the areas immediately around where they form. As of Thursday morning, the ice is still in place at Eagle with water levels still slowly rising. The Yukon River at the Fortymile broke up last evening. There is an ice jam in place 5 miles downstream from Dawson as of this morning. Ice will continue to shift at Eagle with fluctuating water levels.
