2008 Riverwatch Program
DHS&EM’s Riverwatch Lower Yukon Team continues to observe ice and river conditions, and follow breakup points along the Lower Yukon River.  The Riverwatch Team will be providing local contact and VHF radio reports to the communities with potential to be affected by rising waters.

A copy of the yesterday’s SECC’s Riverwatch Situation Report is attached.  This report is updated daily at 4pm.  

This program monitors the breakup of major rivers in Alaska and warns residents along those rivers of potential flooding from ice jams. The 2008 Spring Flood Breakup Guide is posted on our website at http://www.ak-prepared.com/

Flood Watch/Warning
The National Weather Service in Fairbanks has issued the following:

- The flood advisory for ice jam flooding remains in effect until 3:45 pm Tuesday for the Polty Slough at Marshall.  Polty Slough is jammed with ice at this time for its entire length.  The main channel of the Yukon River has bank to bank ice. Some water has backed up into Marshall and a low spot in the road is already covered by water.  Further minor rises are likely and could make the road impassable.

- The flood watch remains in effect until 4 pm this afternoon for the Yukon River from Pilot Station to Mountain Village.  An ice breakup front has passed Mountain Village and was 5 to 6 miles below the village on Monday evening. It was running into ice sheets that may be sufficiently strong to cause the ice to jam. Water levels at Mountain Village and Saint Mary’s would rise quickly if the ice jams.
