As I write this, the Columbia River is flowing through Grand Coulee Dam at a rate of 195,400 cubic feet per second. And, spectacularly, about 25,000 cubic feet you can see spilling some 300 feet down the face of the dam.
At Niagara Falls you would see about 20,000 cubic feet of water falling about 70 feet.
The spill should keep going all week, adding incentive to anyone thinking about visiting the dam for the annual July 4th celebration.
If you’d like to check the current amount of water flowing in the river, over the dam or the level of Lake Roosevelt compared to sea level, you can do that here. (But the data fields might not line up well on a small screen of a cell phone.
Lake Roosevelt, behind the dam, is already basically full, well ahead of last year as the chart below shows.
Someone just reminded me of this piece on the Grand Coulee Dam area, produced by KXLY TV for their Explorer TV series, in which I was interviewed.
They did a great job of cutting in quick and useful information, and it’s worth a few minutes of your time.
One thing I forgot to mention (one of those “I wish I had said” moments) is that the drive through here on SR 155 is actually the heart of a National Scenic Byway called The Coulee Corridor.
