By "locking clip" I mean a locking carabiner. I did not lose the anchor due to any kind of knot failure. Attached to the end of my anchor rope is a plastic loop. For easy anchor install and removal I was using a normal clip style carabiner to attach the anchor to the plastic loop. When I went to anchor up half way down river I released the anchor lock, heard the splash, and then noticed what felt like the anchor had not caught yet. I pulled on the anchor line and felt no resistance and said f uck. My guess is when the anchor hit the bottom, the carabiner must have opened on a rock or something down there and slipped off the anchor. I know exactly where it is and will look for it optimistically when the river drops. I did some searching today and found a guy who sells them for $1.60 per pound, so I'm looking at $56 for a 35lb. anchor. Not bad compared to what I've seen em go for at tackle shops. I'll pick that one up and get a spare ASAP as well.

Thank you,
