hydrilla like what we see in the water in big mats ?
or some kind of grass ?
Yes. Very thick mats of it. Can hardly get to shallow enough water.
I guess the bank or maybe a flat bottom john boat ?
of course if the water clarity is like Ken said rather clear
they may be on the outer edge of the mats as well
one thing for certain I would try to drop a presentation in ANY holes in the mat
for grins try setting your float about 3 foot deep
and fishing the 5 to 6 foot deep on outer areas of the mat
