2008 Riverwatch Program
The Kuskokwim and the Middle Yukon team have completed aerial reconnaissance of their respective stretches.  Both teams will be demobilized from the field today.  DHS&EM is working with the National Weather Service to determine when to launch the Lower Yukon Team.

DHS&EM Operations Section continues to work with local government agencies and community officials as they address flooding issues in their community.  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/

Alaska Spring Breakup Summary
The following is an updated summary from the NWS Alaska-Pacific River Forecast Center in Anchorage. Note:  Even though a particular river or reach may be described as mostly open or open, it is still possible for runs of ice and debris to move through as headwaters upstream breakup.  Please use caution at all times when attempting to navigate rivers.

Recent Breakup Activity:
Kobuk River:  The ice began to run at Kobuk on Monday evening but jammed in the bend above Shungnak. Flooding began Tuesday morning and has increased and fluctuated during the day. The ice at Shungnak and Ambler shifted down river but neither has seen a significant run of ice.

Buckland River:  Most of the upper Buckland River is free of ice with only light runs of ice. An ice sheet has blocked the river in the bend up from the Village of Buckland and backed up a small amount of ice and a large volume of water that was flooding overbank and going through old channels and sloughs. The ice in front of the village has shifted down river and jammed against sheets. This has caused flooding of the Village.

Yukon River:  The Yukon River is mostly open with some ice runs from Canadian border to Ruby. The breakup front passed Galena Monday morning and Koyukuk and Galena Monday evening. The breakup front progressed past Kaltag Tuesday morning, reducing the flood threat at Koyukuk and Nulato. The lower Koyukuk River has a run of ice going into the Yukon at the Village of Koyukuk.

Kuskokwim River:  The run of ice from the upper river passed Stony River Monday night and does not have many logs. The ice jam above Tuluksak broke loose on Monday and the breakup front was passing Akiak Tuesday morning.  The ice at Bethel is running and has reached Napaskiak Tuesday morning.

Tanana River:  The Tanana River is mostly open with occasional stranded ice over most of its length.

Nushagak River:  Report from Ekwok that river is open and boats are using the river.

Copper River:  The Copper River has open reaches over most of its length except the canyon. Copper River tributaries are mostly open.

Susitna River:  There are mostly open reaches below the Parks Highway Bridge to the mouth of the river. There are likely to be periodic ice runs and stranded ice in side channels for a while.

Skwentna River:  The River is mostly open.

Yentna River:  The River is mostly open.

Seward Peninsula:  The Snake River is open at the bridge and in town but still ice remaining up river. No recent reports on other rivers in the area.
