If I was to go fishing here. Are we aloud to keep the fish if big enough??

Yes, you are allowed to keep the fish as long as they meet state regulations.

I have not seen signs for catch and release only. Plus the state stocks the trout there so I believe that means you may keep what you catch and long as you follow state limit regulations

You may keep the fish as long as they meet State of Ohio DNR standards. You also will need to have a fishing license.

Do you need a permit to fish there?

Yes, I caught some fair size blue gills. You can see a deep water drop off, try to to fish just on the on the other side of the drop off.
