* ADDITIONAL DETAILS...
- For Aniak: As of 9am Friday May 8th, the Riverwatch Team
reported that the ice jam on the Kuskokwim River at Aniak
started to move downstream and jammed again approximately 16
miles downriver, below Birch Crossing. Additional ice flushed
from upstream has now piled onto the tail of that jam,
causing water levels at Aniak to rise late Thursday night.
Water is overbank near the Aniak Runway, with water over the
back road to the barge landing and the gravel pit. Water is
also near the AC store and homes on the east/upstream side.
Please see the flood warning in effect for Aniak for more
information.
For Kalskag: As of late afternoon Thursday May 7th, the ice
at Kalskag has shifted. Many river-wide cracks, sheet
separations, and pressure ridges have formed from upstream of
Upper Kalskag to near the islands off Lower Kalskag.
Localized break up has occurred near the mouth of the Old
River, but it has not yet flushed.
