2007 KENAI RIVER ICE FLOOD DELIVERS A WALL OF ICE...OVERNIGHT!
As
many of you may remember, the Kenai River witnessed a rare and power
midwinter flood in January 2007. It occurred essentially overnight after
a large lake in its glacial headwaters released its contents under the
weight of its own ice cap. The result was a sudden flush of millions
of gallons of water down the Kenai which was very low, and largely frozen
over in typical winter slumber. It uprooted large sheets of ice thicker
than most cars and then piled them all up like they were potato chips.
The breaking wave of jagged ice chunks wreaked havoc upon miles of the
rivers middle section; hitting hardest from the Moose River to the Soldotna
bridge: where no shoreline structure or boardwalk was left unscathed.
The
damage to shoreline structures, both public and private, eventually
totaled several million dollars. Remarkably the river and the natural
shoreline rebounded nicely. Much of the cleanup was completed this past
spring and some will take place over the coming summers. Fortunately
our shoreline, despite a thirty foot wall of ice, did not receive substantial
damage compared to most.
While
the Kenai's many glacial lakes are notorious for letting go periodically
as their weight pushes through the ice dams, it is far more common in
the summer and fall months when the river is already flowing and absent
of ice. Having the water arrive overnight, in the middle of winter,
was pretty amazing. The last pieces of ice did not completely melt away
until mid June.
