Found a snap-on cushion floating on Oneida Lake over a week ago between Fischer Bay/Damon Point. White with a grey U shaped inset.

I do not have attachment privilege to post picture here. If you know of anyone who lost one or have an idea of other places to post this
let me know.

You could post it on the local Craigslist in the Boat section, and link the pictures here. That's mighty kind of you for retrieving it and trying to help the owner.

Yeah I'd post it on the Syracuse craigslist and there is a couple Facebook boating groups you could also post a picture of it on and that'll help spread the word.
