I was out playing around with my new sonar, looking for structure, and in about 20 feet of water found this with sidescan:
I would like a second opinion here, but to me that looks like a sunken boat. And of all the water there, I managed to run my boat straight over it.
I will be back at some point with the aqua vu to further investigate, but I do know that is was by one of the spots where they put in cribs near the boat dock, so I might have mistaken the crib for a boat.
