That's a lot of floating vegetation! Looks like you are in the Amazon or something
I'm struggling to positively identify the Lily. It looks like yellow pond lily, but in all descriptions I've read, the flowers are 2-3" across.
These flowers are 6-10" across. HUGE!
And yes, many of the areas I fish this time of year is covered in vegetation.
I was fishing for Pike in this soupy muck the other day.
