I don't think there are any legal issues here. Just make sure the guts sink and are not visable. I for one don't like to launch my boat at a stinky ramp. Seems like the one at Maumelle is notorious for inconsiderate fishermen. I guess they want to prove to people there really are some fish in the lake.
If I am cleaning fish in a secluded cove or stretch of lake, I like to leave mine shallow enough for the coons to find. Otherwise, I just drop the scraps in the lake so the catfish and turtles can eat.
I never like to do it at the ramp.
