Can anyone tell me how long it takes the water on the Holston (not s.holston) to drop after one generator around the Good Hope Church Rd. area. This is the area where the big spring comes in.
Thanks in advance!

4X, CR Outfitters (http://www.croutfitters.com/rivers.html) in Norris has an approximate water flow timeline for the Clinch River on their web site. You might want to check with the Ralstons on the same for the Holston.

Joe Fred-

I was thinking the same thing, but you'er faster at the keyboard. 4X raised an interesting question about the downstream flows below the dams. Cal, at CR, told me their information is anecdotal based upon their observations during numerous float trips on the Clinch.

But since the tailwaters and flows are managed by the TVA, you would think that they would have flow data based upon # of generators, and when the surge would pass certain points. I've looked on TVA's website before, and didn't find any such information.

But for fishing the tailwaters, that's useful info for recreational users of all types.

If you find the info, please post it on the Forum.

Thanks

Bill

The information is not "anecdotal" it can nearly be taken to the bank.
Here's a more comprehensive and invaluable link:

Wish I had the same for the Holston.Going in a few minutes anyway.

Thanks for the link, 4X. Hope you had a good outing. Weather's super!

Kudos to John, Bill & Buzz for the data and to The Clinch River Chapter of Trout Unlimited for sharing it. Maybe, once I retire from my day job, I can help develop similar information for the Holston and other area tailwaters.

I own & use the maps put out by Fishwater Maps (http://fishwatermaps.com/river_maps) for the Clinch, South Holston, & Watauga rivers, and they all have the surge times (how long it takes the water to reach downstream once generation starts) listed for various points along each of those rivers. The drain down time may be slightly longer depending on how many generators were running and for how long. According to the website linked to above they also have maps for the Hiwassee, plus a bunch of rivers in western NC and north GA. Unfortunately, they don't list one for the Holston. Maybe if we offered to take them fishing, they could put together a new map for us.

I had the pleasure of meeting C.S. Gibbs at last year's TroutFest. I was not aware of his maps until then. He is a nice fellow and an accomplished graphic designer with an obvious love for our sport and the great places it takes us to.

Today, Saturday, TVA was "supposed" to generate with one turbine between 2 and 3 PM; any idea if this makes the river at Nance's un-wadable?

I wanted to go but the morning generation had me worried about wasting the gas to Nanc'es.

Maybe a one generator flow "levels out" by the time it gets down river the generating flow is only for a few hours?

Is "Duration of generation" a big factor?

Thanks

Nance's Ferry is never unwadable on a one generator pulse nor is most of the upriver locations short of the shoals below the dam. You will barely be able to notice the water coming through.

The most telling information on the Holston is the predicted average out-flow. It's a big river (length and capacity) so it can take some water. Pulses of greater than one hour should be heeded however.

Water on the Holston was very wadeable around noon at the area I fished.
Unfortunately the fishing was Slowww. Shoulda gone to the Clinch.
