* ADDITIONAL DETAILS...
- At 400 PM AKDT Monday, River Watch observed a run of 20 to 30
miles of heavy ice and high water moving towards the village.
Local observers reported minor flooding is occuring,
primarily on the south riverbank. Expect continued steady
rises through Monday night into Tuesday. If ice stops
completely, water will rise faster. There was a partial jam
noted at South Mouth with Casey Channel and the Alakanuk
Slough as the primary outlets for ice to pass.
At 100 PM AKDT Monday, the River Watch Team observed the
breakup front moving downstream past Emmonak and Alakanuk
with a 30 mile run of thick bank to bank ice and high water
upstream. There are reports that Kwiguk Pass is jamming up at
the mouth and that water will begin backing up into Emmonak.
The high water has caused flooding in upstream areas in
conjunction with this ice run. Residents should take
precautions now and continue to monitor the situation
closely.
- For Yukon River at Emmonak:
At 7:00pm the stage was 8.9 feet.
The record is around 11.5 feet.
