Not a river, but I was anchored and mooching in an area where the downrigger guys come by and cut off fish with thier wire. Anyway, I fell asleep and when I woke up, pulled my anchor, about 30 fathoms. It pulled kind of hard and on the rope near the chain there was a hoochie, leader, and large flasher, lots of line, fishing rod, and reel. I turned it in at the harbormasters office.
