On May 13th, an ice jam formed just downstream of Crooked Creek, triggering a rapid rise in water levels—up to 16 feet within hours. The event led to the worst flooding ever recorded in Crooked Creek.

Above average snow in the Yukon coupled with cold April temps led to a mechanical breakup. On May 14, a 90-mile breakup front jammed downstream and caused water to backup into Circle. The river quickly rose and caused the worst flooding in Circle’s history!

Cold water kills: ~20% of those who perish in cold water do so in the first minute of immersion.
When you fall in:
1 Min: Cold shock – catch your breath.

10 Min: Useful movement – get to safety or stay afloat.

1 Hr: Before hypothermia causes unconsciousness.

During the spring, frozen ground reduces the amount of water from melting snow or rainfall that can seep into the ground. A rapid warming can cause excessive melt water from the snowpack that can overflow streams, rivers and lakes.

There are 2 types of breakup, mechanical and thermal. Mechanical breakup can create dangerous ice jams. Ice jams are a serious hazard to Alaskans.
