D.O. Watch

Got an email from James at the hatchery this morning.

DO level coming into hatchery is 2.0 ppm, temp 48.

He said water is a bit warmer than normal and typically it's 1 ppm coming in. That's good... it may turn within the next couple of weeks with the colder temps forecasted. Need cold and wind- that's best to cool surface temps on Table Rock.

Emailed James Friday- I honestly thought with the very cold temps the lake would show signs of moving... hasn't happened.

He said there's no movement. He thought it would turn by Christmas. With the warm temps forecasted for all this week, nothing will happen. it's got to get colder and stay cold and it'll turn.

Why so much attention to the lake turning?

What is the optimium DO level?

Is it always this low, or is it seasonal?

There is a thread here on the DO. After some research the hatchery folks said above 5 DO is best. LMW this might give you more insight

Thanks Dano

I read the threads and checked out the 2 sites. I understand a lot more now.

Why do you call them pinned sites?

What is the DO level at Taney so low compared to the other 5 listed on the sites?

I did a web search and found this site. Seemed to have some good info

The hatchery personnel like the DO in water entering the raceways to be 11 ppm and the water leaving the raceways into the lake to be 9 ppm. This is achieved by running the water thru aeriation stacks at the head of each raceway. An oxygen injection system is being installed in the new addition and I think in the old raceways as well (not sure) but the addition will help the hatchery achieve this goal.

I was also told that #3 and #4 outlets will reopen when the raceways are done BUT my thinking that #3's flow would increase was wrong. they are actually going to redirect the water from the new raceways up to #1 and #2 and increase flow a bit, lessening the flow from #3 and #4. Why? In the fall, #1 and #2 outlets keep the upper lake alive and lessening the flow would only hurt the fishery. But in the fall when they need browns to move up in #3, up the ladder they're building into the spawning house, they will increase #3's flow to accommodate the run.

Shepherd wants to create a youth/handicap fishery there east of the new expansion in the way of a short stream and pond at the base of the stream. #4 would be the pipe that now exist about 200 yds below #3 oulet. But this plan is not yet funded.

Pinned sites are threads on the forums that remain "pinned" to the top of that particular forum for easy reference ie: generation charts, maps etc.

Phil,

It's good to hear that consideration is there for the children and the handicapped.

LMW,

Wait until you start fighting trout after the lake turns and the DO rises. They will have alot of more fight in them and you will hear your reel scream a little longer than usual.

Can't wait.....Don
