The increased hydrostatic pressure from the high river water searches for relief and finds it by under pressure surging into the GW strata mixing with it and changing its make-up with the newly mixed water pushing the ground water up into the pond.
It will be interesting to see if the normal GW is changed by the river water mixing in under pressure during high water periods.

The increased hydrostatic pressure from the high river water searches for relief and finds it by under pressure surging into the GW strata pushing the ground water up into the pond. I haven't seen evidence of GW changes during high water periods. It is possible that the GW strata (being primarily sand) filters the water and keeps it from modifying the GW to any great extent. It is also possible that the GW flowing through the pond blocks changes coming from run off waters in the river. More likely, it is a combination of these two factors. Now that there is a test well located in the path of incoming GW, monitoring will answer some of our questions. It will probably create new questions, as well.

I would be shocked if no new questions arise.

Updated Weekly D.O. and temperature are returning to their fall convergence track. Clarity dropped 30 inches since last Saturday so some plankton clan must be getting active.

DOs up to even as clarity drops. Plankton must be producing some O2.

Could it be your fall diatom pulse? Maybe a brownish hue?

Those are nice readings. Perhaps after this rain front passes and we get a good day, I should run down a dozen 10" chubs and we should quick strike rig for Darlene or one of her sisters.
Good morning Dave, I've checked the ships systems, and everything appears to be running normally.

There was a large temperature drop and a large clarity gain this week. The water is clear down to the bottom. My Secchi disk only has 11 feet of rope on it so...... GW: 55.04F DO .42 Updated Weekly

The stick e-mailed me that the latest graph didn't match the commentary. After a re-load it showed up fine.
Is anyone else having this problem?

It was cold and windy out there today. We missed the 10 inches of snow, thankfully. When the temperature is 34 degrees and the wind is blowing 30 mph you wear the warm stuff doing pond observations! Updated Weekly

The clearer the water the more DO ?

The clearer the water the more DO ? Normally that would be a "no" answer. But there are more factors to consider: Water temperatures are cooling so less O2 is being consumed by the less active fish. Reduced nutrient load produced by inactive fish. Cold water holds more O2. Clear water increases available sunlight for photosynthesis. If you look at the data, the clarity has dropped slightly from its high so there may be some plankton activity re-occurring. The circulator is running 24/7.

Very good grasshopper. It is truly a 3-D web and not a chain.  It would be neat to quantify the effects of the circulator. I bet a big effect.

Na - Na- Na - you have 7 more degrees to go. Even then it will be to thin to walk on for a while.

Yeah, but with the temps that they are seeing up there now, I think those 7 degrees will come pretty quick!

Agreed on the 7 degrees fading fast. The highest daytime temp for the next 7 days is today at 35 degrees. Single digit night temps are forecast starting Wednesday. That will give the circulator something to fight against!

5F degrees over night. The circulator lost the battle with the ice in a final valiant effort.
