Default Norris Dam (Flood Gates Opening Up)

Got a call from an old TVA Friend that Norris was opening up today through Friday.

VIDEO OF THE GATES OPENING BELOW:

Is this going to hurt the sulfur hatch?

Yes,its true...the flood gates are open. We went out by there this evening.

I'm honestly not sure if it will hurt the sulfur hatch. I'm too uneducated about bugs to answer that one...

The sulphurs will be gone if they are not already due to the extensive generating. The sulphurs on the clinch are swimmer type not the clinger type, so heavy generating will wash them out for the season.

On another note last time they opened the gates the sulphur hatch was down for about 3 years, and that was 6 years ago when they opened them up last.

Atleast I got to fish last Tuesday evening with sulphurs coming off heavy. I was able to catch 5 fish over 14" and several more in a 2 hour stretch. My buddy and I were like a couple of giddy little school girls, and we couldn't wait to do it the next day. Then the generators fired up, and haven't stopped since. I just hope they are on next year.

Good news though, the sulphurs are coming off like crazy on the holston.

What's it going to do to the water temperature?

What kind of impact will this have on the fishery?

My neighbor said it's going to be spilling for a few days...

I believe the spilled water is warmer than the released water, and if true, the water should be warmer than a normal two generator generation. We really aren't into hot weather yet, so I doubt that would be a problem.

In the past, this has not been good for the sulfurs. I would anticipate a weaker hatch for next year and maybe for the next few years.

On a brighter note, the TVA website anticipates a more normal generation on Saturday. Hopefully, the damage by the volume of water will be limited.

Yes, the spilled water is for the most part, surface water, while the water used for power generation is pulled from deeper in the lake. So it will be warmer.

Being a tail water dam the water is obviously warmer on top, then when it is over 100 ft deep coming from the bottom. With that said the water temps on the lake aren't even in the 70's yet there will be no problem with the heat.

I would not count on the generation chart for this weekend. They are not planning on closing the gates until friday. If that is the case and they don't generate at all it will take a good 12 plus hours to drain near 61 bridge. The fishing should return to normal summer fishing in a week or two. I am hoping that the fish will be very hungry when the water slow down.

I am hoping the trout are fat and happy after gorging themselves on shad and whatever came through the dam during all this flow....

I was up at Big Ridge two days ago and WOW.
The water looked to be at least 5-10 ft. higher than it is supposed to be.
