Recently Fairbanks and the surrounding areas have been getting a lot of rain. So when Jack and I visited the Chena Dam the other day the floodgates had been lowered in order to prevent high water from flowing downstream toward Fairbanks. This results in the river backing up into the reservoir area behind the dam but saves Fairbanks as it has many times since it was built almost 40 years ago.
Dermot Cole of Alaska Dispatch News wrote in 2014 when the floodgates were lowered then that Fairbanks’ “most effective flood insurance policy … takes the form of an unusual dam with four 30-ton gates that operate like giant garage doors, stemming the flow of high water when the river rises. The floodgates are one element in an extensive federal flood control project that cost a quarter-billion dollars by the time of its completion in 1979.”
