What is this? (Side scan

What is on the bottom right? The zig zag pattern?

Almost looks like the concrete stops on a low water crossing/bridge. Quite odd, is this near a creek channel?

It's way up the river on McQueeney

Well that will rule out 90% of us knowing since the lakes mostly private. But since it’s a river system, I’d guess it was some type of old dam or bridge, before the lake was built. Just a guess though since I’ve never fished that lake. Concrete and rocks usually give a bright white return like that one is showing.

Thanks. I just got a new graph with side imaging so I’m trying to figure it out.

Old retaining wall???

Maybe so. That looks pretty similar. I didn't mark it but I'm going to go back and find it. It was really long.

OP looks like a phone cord from his camera

I know one thing, I wouldn’t want to get my prop into it!

can you get over top of it and scan again?

Scattered pieces of SpaceX rocket booster that missed landing barge.

I'm going to go back to it this weekend

Agree

Hi npl_texas

You're probably are already aware of it, but the lines showing up on your right side and down scan images are usually due to your LSS transducer being mounted to your jack-plate and getting ringing from it. Installing a holeshot plate or lowering the transducer will normally remedy this.

I don't know why I find your post funny..

But OP, that's most likely what that is underwater
