The first pic is definitely trees. You can tell on the imaging with the vertical stands. If you up the contrast a little, you can see more of the branches.
The second pic is possibly a brush pile on a structure change in depth (little drop-off). Possibly some trees on top, but there are fish working a bait ball near the surface.
