Latest Dissolved Oxygen and Temperaturre Profile for Table Rock

[mojorig]

On the USACE website, they post monthly DO and Temperature Profiles collected by the USGS for the White River Chain of Lakes (http://www.swl-wc.usace.army.mil/pages/Pertinent_WQ_Data.htm). Here is the most updated one for Table Rock (http://www.swl-wc.usace.army.mil/pages/reports/remote/profiles/tabpro.htm). I hope this link will be useful for someone.

Wonder which part of the lake this was?

[mojorig]

Sorry, I forgot to add that part. The readings at each lake are taken at the buoy line at the dam.

i am quite sure that the rest of the lake does not read like that, but it does tell one that in the dam area there is not much need to fish any deeper than 20 feet.

i might also add that if you look at the o2 levels and the temperartures, the bass are living in a farm pond, pretty much.  normally the 70 to 72 is where the thermocline and best oo2 levels exists.  but, sure goes to show just how high water and constant moving water affects the lake.

Any ideas why it spikes again around 130?

[Alex Heitman]

It spikes again because that is where the second thermocline is.

Still don't understand where that oxygen came from if there is none above it for 100ft? The temperature isn't suddenly out of pattern?  I didn't know that there was another thermocline 130 ft deep...cool.  I'm gonna need some heavier spoons lol

There is no 2nd thermocline in that profile. Look at the temperature/depth numbers. From 40' on down, there's only a consistently stable 1 to 1.5 degree drop every 10 feet.  Compare that to the ~6 degree drop from 30' to 40' where the real thermocline is strongest at 32-33 feet (2.3 deg/ft).

The "spike" between 100-150 feet is merely oxygen that hasn't been used up yet. Were the summer to continue, that too would be gone in a few weeks. It's nothing to drop a spoon to though, at <2ppm O2, not even cats or carp can survive there.

The "spike" between 100-150 feet is merely oxygen that hasn't been used up yet.

This profile is from the 'biggest' water, right in front of the dam. The sheer volume of (in this case) 100-150' water in the big end seldom is devoid of O2 because it's so large. The fish that prefer the cooler water can usually thrive there, trout at Bull, stripers at Beaver, or walleye at...

You won't have to go too far uplake before that oxygen pocket peters out.
