Looks like a carp rolling. I would suggest throwing a spinnerbait, buzzbait, or topwater frog to cover lots of water and find any of those bass that are aggressive. Float fishing takes way too long, you cover so little water. Especially on a new body of water like that, the more casts you make and the more water you can cover, the more success you will have and the better you will be able to identify a pattern (are they up tight to shore, are they sitting under clumps of weed, are they roaming around on flats, do they like a fast or slow retrieve, etc)

I won't stay long if I were there.

Maybe Salmon For the First Big Splash, then bass at the end

Enjoy last trip of summer I believe,you might be start kayak salmon fishing at this time lol... all the best brotha.

do they sell worms there?

Nice park, but that poop!
