ESFAFG The Yukon River is open from Tanana to beyond Kaltag. With water levels remaining low, stranded ice remains on banks and in side channels. Above Tanana, from Ft. Yukon to the confluence with the Tanana River, the river ice remains intermittently intact and very degraded. As this ice begins moves out and water levels eventually rise, ice runs can be expected to continue through the end of the week.

ESFAFG Based on ice running by Galena for most of the day on Saturday, it is likely that the in-place ice from the Boneyard to the Nowitna River is getting pushed out. The river is open from Ruby down to Kaltag with continuing ice and ice stranded in shallow areas. In-place ice remains several miles below Kaltag as of Saturday evening.

ESFBYZ Expect very warm temperatures through Monday. Enhanced snowmelt in the mountains will continue to increase flows on area rivers and streams through the first part of the week. While flooding is not anticipated on larger rivers and streams, there is a chance that some smaller streams could reach bankfull in and near the foothills, producing minor flooding. At the very least, stream flows will be much higher with the increased snowmelt. Water rises will occur first on small streams flowing out of the foothills, eventually arriving on larger rivers and streams. The rate and magnitude of the water rises
