I am in almost the same boat as you timewise and stocking numbers. I saw my 12 inch lmb on nests this year. Don't know if any fry survived because I have a surplus of cnbg they would have to contend with. But in my opinion, your lmb should have spawned this year. They really only need to be about 10 inch to spawn in the right conditions.

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
