I lost 2 I put out last year. Didn't think there was too much current till I got to looking for a stump when the water was down and a gravel bar nearby that I was using as a reference, was totally rearranged from last year. When I went over it with my gps the stump was in 3' where it had been 6' last year. Won't put condos on that flat like I did before. They just washed out.
