Growing more and more frustrated because I can't fish due to generation, I decided to email TVA to get a better understanding of how they decide when and when not to generate. Below is our conversation from back in early December when there was a lot of day time generation.

Me:
It seems as though most of the heavy generation on trout tailwaters occurs during daylight hours when most people would attempt to fish. It seems to me that the trout stocking program is a wasted investment if citizens don't have the opportunity to
actually fish. Is there any particular reason why heavy day-time
generation is taking place?

TVA:
Thank you for your inquiry. In your email you did not name the
reservoir/tailwater - Could you please tell me which reservoir? Thank you.

Me:
Thanks for your prompt reply. The reservoirs/tailwaters I'm specifically referring to are Center Hill, Tims Ford, and J Percy Priest. Center Hill (Caney Fork river) and Tims Ford (Elk river), in particular, are sights where people have been known to travel from across state lines just to fish our fine Tennessee waters. On many occasions, I have personally received calls from colleagues and fisherman from all over the US asking about fishing conditions at both tailwater locations. Over the last few months, the conditions on the tailwaters haven't allowed the opportunity to fish at all. I'm sure that this compromises revenue from tourism and the purchasing of fishing licenses for the state. I certainly understand that acts of nature can dictate the need to release water. My question is whether the generation/release could occur during night hours in order to allow people to fish and use these precious resources during the day?

TVA:
We appreciate your concern. While Tims Ford is TVA-managed, Center Hill and J Percy Priest are managed by the U.S. Army Corps of Engineers; however, they follow the same rule of thumb that TVA does. While we understand the difficulty this may cause for people who wade to fish, we run the units during the hours that have the highest demand for electricity. There is generally not much demand in the middle of the night. If we cannot supply the electricity that is needed on the hours when demand is highest, we have to find other means to supply our customers with power. This would mean generating with more costly sources like combustion turbines or purchasing electricity from another supplier. If we purchase during hours when the demand is high, the cost to our customers is likely to be high as well.
 
So what is your point. That TVA is in the electricity business not the fishing business. I know we have a lot of water that needs to be moved. Don't get me wrong, I am sympathetic to your needs, but TVA does have to generate. We've had more rain this year than past years. I'm concerned on how it will effect fishing but what can you do.
 
look on the brite side,less opportunity means less fish caught & they will grow quicker with the water moving more bait/food past them,next year may be a record setting year,coarse my cups always half full instead of half empty :) ,mike243

Had you adequately read my questions and subsequent responses...you should have comprehended that I never accused TVA of any wrong doing. It was simply put...a question about generation. From TVA�s responses, I was educated as to why they generate when they do (electricity demand) and hopefully someone else on the board was educated as well.
 
This may be a bit crass, but I'd say...get over it. Like he said, you can't control the TVA as far as fishing goes. And frankly...the BEST fishing BY FAR for BIG FISH is under these conditions right now! We caught BIG browns when the water was 15 feet up the sides of the trees last April, and while I've been more into muskies lately, I'm sure if I go out, I'll find it the same if not better. Believe it or not, trout are designed for current and do just fine in these conditions... in fact, it concentrates them even more at times. I'd say get out there and fish, and stop worrying about the things you can't control. you might be surprised at what you get...and hey...if you have to put away the fly tackle a bit, who cares. Sometimes it ain't the best way to go and there's nothing sacrelige about that. Go throw spoons at the dam, or big jerkbaits down the river...or streamers if you so desire, but know that this high water can make for great fishing, and it most certainly isn't hurting the trout at all.
 
passing over the caney fork on the way home yesterday, it is out of its banks. fishing under such conditions is difficult at best and VERY dangerous!

If you're in a decent sized boat and have any common sense, it's not that dangerous at all. People fish below Watts bar and larger dams all the time and do just fine. The Caney is no where near the output of those fisheries, and frankly...it makes it easier in alot of ways. Find the eddies...find the tributaries. That easy. Everyone told me you couldn't catch trout under 2 generators. Turns out its probably the best time for a big brown.

I'm with Mike on this one......big trout come this spring, summer, or fall when they finally cut off. I had a great day on the Clinch about 3 weeks ago when they had it cut off in the afternoon for about 3 days. I had a temp of over a 100 but went fishing because I knew i wouldn't get this chance again with the rain pattern. Wife threw a fit when I got home, but 25 trout later it was worth it!

The fish will still be there. TVA makes electricity, not fish. The trout are secondary....remember, before the dams there were NO trout in these waters.

Now for the second and third time...

For those who have miscomprehended my post, the question I had for TVA was about day vs. night generation. I have only fished these waters for the last 2 1/2 years and my observation has been that they generate mostly during the day. Even with all the precipitation, the recent generation breaks that have occurred few and far in between, have occurred mostly at night. Again, I'm aware of TVA's purpose (energy and flood control) and I haven't accused them of any wrong doing. I do admit that I have a bad case of "cabin fever" but that's my problem and not there's. I merely asked a question to satisfy my curiosity. Based on TVA's response to my question, I am now informed that energy demand = generation. Because they can�t store energy, it must be generated when needed. Those on this board who had the same curiosities as I, are now informed as well.

Now for those of you who are able to fish in the given conditions...more power to you and I wish you all the luck. In fact, post pictures of your catch�I'd love to see 'em. I don't doubt that fishing is better right about now. I personally am not equipped or experienced enough to deal with the given conditions. It ain't worth risking my life.

7mm�I�ll take my medicine if you wear your glasses :grin:
 
It's frustrating, but you just have to keep checking the generation schedule. While in school at tech, we called all the time and when there was a break, we'd head down and wade. Sometimes we'd go at night and fish from the bank below the dam. It tva and their generation schedule gets you frustrated, you must not be married. lol

You hit the nail on the head!
Married + tailwater generation = Stay inside for more Honey Do's. That's enough to make a man go nutts! :crazy:

7mm...I'll take you up on the Clinch someday ;)
 
TVA has been more then open to suggestions from fisherman. Heck, the Clinch has a recreation flow on it for most weekend during the year, as does many of the others.

Did you stop to think that the reason they are running so much water for the past few months, might be the extremely high amounts of rainfall? Flood control is one of the primary functions of TVA, followed by power generation.

We are fortunate to have TVA, and not have to deal with with the Corps on every river. Which brings me to my next point, you inquired about Center Hill, that is a Corp dam, in other words not TVA's call on power generation.

Not always true.
 
As far as I know, they've been going night and day with the recent rainfall. There hasn't been a biased choice on time, and historically, I know from personal experience that generation runs through the night and gets cut during day just as much as it run through the day and gets cut at night, most times of the year. Get out...and fish.
 
I've seen hundreds of gulls while driving over Percy Priest dam for the last 2-3 weeks. If there's a shad kill on Priest...I'd be willing to bet that there's a kill on the Caney.

The kill isn't "on" the caney necessarily, they get pulled through the dam via the generators, and if they sluice or spill it just makes it that much better.

Gulls are here by the thousands regardless of a big shad kill, they migrate south when their home waters freeze up, just like ducks.

When they fly immediately above the water surface in huge swarms around generation discharge, I assumed that they were feeding. Maybe not??
 
Setterman,
Me and shore were out at the Caney dam a couple hours yesterday. No luck...we were going after rockfish...but I can tell you...there is a kill. The gulls were blitzkrieging the water almost constantly...and I don't think they were bobbing for apples.
 
I don't doubt it as cold as the weather has been this year, it is very common. The generation just pulls them through the turbines and passes the joy on downstream. There is really nothing in a tailwater to cause a massive die off like there is in the lakes, as the water temp in our tailwaters is fairly steady, unlike the reservoirs.
 
Setterman,
Maybe I missed it, but I don't think anyone was necessarily saying [maybe it sounded like it but] that the kill WAS in the Caney itself. Technically Center Hill is the Caney, but I figured anyone and everyone mentioning shad kill in the Caney knew already that they were dying in the lake and being sucked down through the gens. Puree.
