I was fishing, using a downrigger, the cannon ball was 150 feet down in 200 feet of water, when suddenly the steel cable started pulling from the downrigger

I tried to bring up the cannon ball (its an electric downrigger) and it wouldn't budge. I dropped the ball a few feet and then tried to bring it up, and it got unstuck from whatever and came right up

The bottom of the bay where I was fishing has no sudden drastic changes in depth, what else could it be other than a shipwreck?

The location is georgian bay, ontario. Colpoys bay more specific. I found a news story about this ship being found in 2018 in the same body of water where I got the snag.

The location isn't public. I have a feeling that I might have found it, or possibly the location of another wreck

Im interested in hearing what else you guys think it could have been

Interesting and scary

Yeah. I don't think it could be anything else.... might do some scanning today. If I get something cool showing on my fishfinder ill post it up

Idk why but i feel like itll be dangerous lol stay safe!

Whatever it was caught on had to have been down like 150 feet! So exciting to wonder what it could be
