Navionics chip not reading river channel correctly

I’ve noticed on ray Hubbard and fork that the navionics chip i have in my lowrance elite 7 hdi graph doesn’t show the river channels accurately. Anyone know about this?

I'm not surprised. My Navionics Platinum card was absurdly wrong for the Sabine River around Orange until an organized mapping project corrected the phony data.

You happen to have or can get me screen shots of the areas you are talking about? Just a few for an example would work.
