US drought monitor map as of July 19 of this year. Parts of eastern Oregon and northern California have eased up. A bit. Includes Alaska, Hawaii and Puerto Rico.
Oregon and Washington aren't quite so bad off although there is a dark brown area that looks to be about where Bend and Sisers are located. Just dong a little sifting throught the websites yesterday apparantly the flow on the Columbia is down from the old normal. Say about fifteen to twenty years ago. The last time any water gushed around here was back in the nineties.
A map of the area drained by the Columbia River system. Rising in British Columbia the rivers drain an area the size of France. By volume it's the fourth largest river system in the US and the largest draining into the Pacific. Small wonder greedy eyes to the south covet the waters of the Columbia.
The system supports over sixty dams tying toether irrigation, hydropower and a network of locks and barges that ties the Port of Lewiston to the Pacific. And has cut down the salmon runs to almost nothing including the destruction of the fishery at Celilo Falls. Somehow I don't believe that naming the reservoir Lake Celilo quite makes up for that.
The Snake and the Columbia form the squiggly sections of the borders between Idaho and Washington. During the low flow parts of the years Spring, Summer and Fall waters from the Pacific can flow up to one hundred six miles up the river. So far seawater hasn't made it into the Willamette River which joins the Columbia just over one hundred miles from the Pacific.
There are four dams on the lower Columbia between Oregon and Washington; Benneville, The Dalles, John Day and McNary. All four have lochs and power stations. The Columbia reaches Oregon just east of McNary dam. And the weirdest thing happened when Rick took us over to the Washington side where the loch is located several years ago. We lucked out and the loch was in use. As the water drained out to the lower level the illusion was that we were going up, not that the water was going down. Reeealy weird.
Unfortunately I can't find an opinion piece I read yesterday asking why water from the Columbia can't be sent via pipeline to the southwest. One of the comments on the piece claimed that diverting ten pecent of the flow from the from the point where the river enters Washington. I can only assume the commenter hasn't seen a topo map of my home state.
His theory was that diverting ten percent of the flow would not harm the salmon runs. Any more than they already are. More on that later. I'm assuming some sort of pipeline. I'm guessing they'd want to tie into the Colorado system somehow, somewhere. I believe the closest the Colorado comes to Oregon is donn the corder of Utah. A long way to go and a lot of rugged real estate in the way
Now about that ten percent of the flow. How will that affect power generation. Can wind generation take up the slack? How will losing ten percent of the flow affect barge traffic. And how will that ten percent really affect the salmon runs. Will the diversion cause the waters in the reservoirs to warm up even more? Warm water and salmon don't exactly mix.
Water from the Pacific already makes it just over one hundred miles up river. What would be the effect of a ten percent diversion have on possibly increasing that distance. The mouth of the Willamette is one hundred one miles from the mouth of the Columbia. Could this affact water quality in the Willamette. What if any effect would this have on wells near the river? Add in rising sea levels and what happens to the that equation?
This tale certainly grew with the telling. Haven't written anything like this in a very long time. Feels good.
