262 first-hand accounts of flood events in Alaska, ranked by impact. Each is a NOAA-written narrative of the moment.
Two Bering Sea low pressure systems tracked into Western Alaska from August 15 through 18th bringing a period of nearly-persistent southerly winds which led to storm surge and coastal flooding along the Kuskokwim Delta coast and backed up flow along the lower Kuskokwim River.

Read the full account →A significant run of water and ice along with an ice jam that extended 10 miles up river of Marshall produced moderate flooding in the village of Marshall.
Read the full account →A significant amount of water and ice combined with ice jams in the vicinity of the village as well as downriver produced flooding in the village of Alakanuk. The flooding was compounded by 2 to 5 miles of shore-fast ice at the mouth of the Yukon River.
Read the full account →An intense Bering Sea storm with its associated front into the north Pacific produced heavy rain along the Alaska Peninsula. The combination of the heavy rain and a high tide resulted in excess water flow from Chignik Lake becoming dammed in the mouth of the river and flooding…

The water levels along the Porcupine River at Old Crow rose dramatically during the weekend of May 18th and 19th, due to heavy snowmelt and remained high.

Read the full account →An Atmospheric River brought over 7 inches of rainfall to Seward, AK, with 6 of 7 inches falling within a 48 hour period. Runoff from the rain pushed streams across the area into flood stage, with levees in the region being threatened by erosion.
Read the full account →On Thursday morning, reports were received that significant rises had occurred on all tributaries draining into the Copper River. The Tazlina, Klutina and other streams and rivers in the western Copper Basin crossing the Richardson Highway were reported to be flowing at…
Read the full account →An ice jam near Ruby caused the water levels on the Yukon River to rise significantly on the 10th, and flood stage was exceeded by 0500AKST on the 11th. The water level crested at 41.5 feet at Ruby 1000AKST on the 11th, and remained above flood stage until 2100AKST on the 13th.
Read the full account →Minor flooding occurred on the Kenai river downstream from Soldotna just below Big Eddy. The flooding was due to water backing up due to an ice jam. The jam formed in below zero temperatures, which created frazil ice.
Read the full account →High water in the Kuskokwim River at McGrath due to snow melt caused serious erosion to the levee along Takotna Avenue that acts as a levee that keeps water from flooding the city of McGrath.
Read the full account →A strong low developed to the west of the Aleutian Chain late on the evening of November 13th and moved into the western Bering Sea, eventually moving east into the western coastline of Mainland Alaska by the afternoon of November 15th.
Read the full account →A weather front brought from 1 to 2 inches of rain to the headwaters of Birch Creek and Crooked Creek. The rain fell on a residual winter snowpack and resulted in significant runoff due to the combination of rapid snowmelt and the heavy rainfall.
Read the full account →A prolonged period of well-below-average spring temperatures combined with an above-average winter snowpack created a dynamic breakup of the Yukon River. This resulted in numerous ice jams and snowmelt flooding on the Yukon River.
