2008 Riverwatch Program
DHS&EM’s Riverwatch Field Teams continue river watch of the upper Yukon and the Kuskokwim Rivers.  

The Upper Yukon team continues their land and aerial reconnaissance of river ice conditions along the Yukon River in the Fort Yukon area and to get another perspective on ice conditions on Porcupine and Black Rivers.  The team reports that it is flowing strong upstream, they have located an ice jam downstream, the rivers looked rotten and that the potential for flooding is still present.

The Kuskokwim team has arrived Aniak.  This team will be making their aerial reconnaissance as scheduled which is concentrating their initial surveillance on the area between Aniak upstream to Stony River.

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 Warning/Watches:
The NWS in Fairbanks has issued the following:

- Yukon Flats and surrounding uplands including Fort Yukon, Venetie, Central, Circle, Stevens Village, Beaver, Chalkyitsik, Birch Creek, Circle Hot Springs, Eagle Summit and Twelvemile Summit.  Flood watch now in effect until 10 pm this evening for the Yukon River at Fort Yukon.  The flood watch is in effect for the Fort Yukon area until 10 pm this evening. The ice began to run past Fort Yukon at about midnight and has been running continuously through Thursday morning. The ice in the main channel about 4 miles down river has not yet broken up and the ice run has been diverted into side channels.

- Middle Tanana Valley including Fairbanks, Fort Wainwright, Eielson AFB, Ester, North Pole, Moose Creek, Two Rivers, Fox, Chatanika, Chena Hot Springs and Sourdough Camp. Flood watch for the Salcha area from the Valdez trail southward through Friday morning. Ice continues to run in the Tanana River, so an ice jam could reform. Flooding in the Salcha area is possible.

Alaska Spring Breakup Summary
The NWS Alaska-Pacific River Forecast Center in Anchorage has issued a spring breakup summary for Alaska.
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:
Tanana River:
The Nabesna River at Northway ice was starting to open up but there were still lots of ice in the river. The ice went out at Tanacross on Tuesday. An ice run was reported at Big Delta on Wednesday. From the Little Salcha River to Stringer Road there were several ice jams causing local flooding. At Fairbanks the river is about 30 percent open with no ice flowing. The Tanana at Nenana tripod tipped on May 6th at 10:53 pm. Ice was reported to be in place at Manley.

Yukon River:
The ice went out at Eagle Saturday afternoon and there have been periods of ice runs early this week. The breakup front arrived at Circle overnight and cause minor flooding in circle on Wednesday morning. The ice between Circle and Fort Yukon appears rotten to within 20 miles of Fort Yukon and then appears stronger to Fort Yukon and below Fort Yukon. At Stevens Village the channel in front of town is reported open with very dark and rotting ice in the main channel.
The lower Yukon River still has solid ice in place.

Kuskokwim River:
At Mcgrath there is now water flowing along the edges though the ice is still relatively solid with cracks starting to form. At Stony River there was a report that the ice in front of the village had run on Tuesday. At Sleetmute the water level has risen about 2 feet and the ice continues to lift with shore ice popping. Crooked Creek, a tributary of the Kuskokwim, it is reported that the ice has broken and is running. On the lower river from Napaimiut downstream the ice is reported still solid. The Aniak River is open.

Ice is reported to be intact and rotting with open leads along the edges.

Copper River:

Water is backing up behind the jam and has inundated the school road. The Copper River is mostly open from Copper Center to below Chitina. From 20 miles below Chitina to Wood Canyon, ice is backing up. It is mostly open from Wood Canyon to the Tiekel River and from Million Dollar Bridge to the mouth with the area in between still relatively solid ice.
