Bigsur,
That is actually quite a bit lower compared to some of releases a while back. When they sluice; water comes out of the bottom vents and it is much more drastic. Here is a picture from February of this year when they were running 20,500 cfs. Thanks for sharing you great pictures and notes.

They keep it higher in the winter now, and that may be a result of the boat docks etc, they have never explained and I personally believe this is why we see regular flooding events on the river.

As I said TVA needs to seriously rethink their approach to water management. Something has changed, and it has nothing to do with global warming/climate change as some might suggest. Last I checked the glaciers in the Clinch watershed disappeared a while back
Jim,
You are exactly right! Some of the money-rollers that have homes and developments on the lake leveraged some of their connections to have TVA maintain a higher winter pool so they did not have to move their docks so much or so their $100,000 docks did not warp if they were beached. It was actually a news event and I think there are some press releases on the internet if people wanted to search and read them. Seems like it was about 10 years ago when this change occured...

Also; all of the years of data and forecasting until this change should be disregarded for planning releases. I hope they are taking this in to consideration. When I look at the previous year's data and statistical graphs; the recent years seem very off from the parameters of historical information.

I do think the extra oxygen is good for the river and the higher flows are good to rejuvenate the river bed at times. But, extended flows of high water are bad for the vegetation and bugs that depend on the light the low water allows. Plus; we fly fishermen do not get to fish as often.
