I didn't use my boatman patterns because my Muncher fly works so well as well as my white phentex humpy. Both have similarities to boatman/backswimmers.
I did something different that I haven't done for years and that is putting two leaders off of the fly line hoop. One with two feet of mono and the humpy, the second with 12 feet of fluro and the Muncher. The recent stockers are not so proficient in taking the dries but pretty good with the nymph! Of course I was after 2nd year fish or older. I got this one in and had two other big rises. I'm pleased that there are still some older fish in this favorite lake of mine. I don't understand why other fishers just don't get it. If you take all the fish out, you have lousy fishing and not much in the pan either. This is a very small lake and so a fish this size is pretty good. I have got larger ones but rarely.
The otter is still there. I'm going to ask OMNR if they will trap it. There are other more drastic measures that could be taken as well.
