I was out this evening just graphing and I found that when I got deeper than 25 ft it was showing all the blue up to exactly 25 feet even when it was 35 feet deep. I have also noticed that once it gets completely dark the whole screen will be covered in blue like this. I was thinking maybe a thermocline?

Doubt it's a thermocline. Too early in the season, you would see more of an even/hard return line, and I believe something would show in the side imaging. You also have fish down there. It looks more like a sediment layer to me.

You have a couple of bait balls in mid-depths, baitfish on the surface, some feeding bass... So it could also be really spread-out baitfish.

I would say sediment layer, i see that around a lot of road beds for some reason. There is fish and bait fish obviously, but i wouldn't say they're feeding by any means. It looks like they're just suspended on the hump or whatever you're graphing

I've seen this a few times. Before the sun comes up, solid blue below a certain depth from 12 to 25 feet or so. Once the sun is up in the sky a bit, its gone. No idea what it is.

My only guess is baitfish that are spread out, since it goes away in the sun

It's like when night fishing and the screen is filled with random blobs and blotches. I've heard everything from algae to jellyfish. Don't know what it is.

Big ball of baitfish and several white bass, ignore the black most the time it's just artifact.

Agreed, it's just an artifact. There's not anything down there.

The active feeding fish do look like white bass

Adjust surface clutter and sensitivity. Looks like sediment floating above bottom. That disturbance on the left side of the SI shot at the boat looks like maybe a transducer setup issue. Maybe an expert will pipe in....I could be totally wrong.

Agree with Collincountytx 100%. In addition with all the high water and suspended sediment it's hard to keep sensitivity adjusted. My best graphing is winter in cold water.
