Hydrologic Outlook issued May 3 at 10:43PM AKDT by NWS Anchorage AK
ESFAFC As of approximately 19:30 AKDT Saturday, McGrath ice started running. Water levels have risen but remain below the bank. Ice is very weak and disintegrating as it moves. McGrath has no flood concerns at this time. As of approximately 20:30 AKDT Saturday, Stony River has ice running past. Water levels have risen 3-4 ft and are expected to continue to rise. Residents are not expecting the water level to reach airstrip level. This ice run is more dense, with more water volume, a lot of wood, and running faster than Thursday night. This ice run is most likely ice

ESFAFG An ice jam above the mouth of the Fortymile River has remained in place since Thursday. With the cooler temperatures snowmelt contribution to the Yukon has not increased water levels at Dawson so this jam has been stable and will likely erode from the downstream side. In this scenario, Eagle and other locations along the Yukon that currently have open water can expect eventual ice runs accompanied by a significant rise in water levels as this jam releases and potentially adds to the current jam downstream of Calico Bluff.

* WHAT...Flooding caused by an ice jam continues to be possible. * WHERE...YUKON RIVER EAGLE TO CIRCLE * WHEN...Through Wednesday morning. * IMPACTS...Creeks and streams may rise out of their banks. Low-water crossings may be flooded. * ADDITIONAL DETAILS... - The Yukon River at Eagle broke up early Thursday morning. The breakup front has since stalled downstream of Eagle, likely near the Tatonduk River. Water levels above the breakup front remain relatively low. An additional ice jam east of the Canadian Border, 6 miles upriver from the mouth of the Fortymile, is backing up water. With the current cool temperatures

ESFAFC As of 19:15 AKDT Thursday, ice began running past Stony River and water levels rose approximately 2 ft. As of 21:00 AKDT the ice continues to run and the water levels are steady. The River Watch team on Wednesday saw no intact ice until 8 miles upstream of the Tatlawitsuk River. River Watch also confirmed on Wednesday that the Tatlawitsuk, Swift, and Stony rivers were all free of ice. On Thursday evening, local residents in Stony River assume this run is intact ice that was released between Devils Elbow and upstream of the Tatlawitsuk River. At this time, the
