Please post here if you notice that they are spawning next spring. I'm watching mine in NE Missouri. Hoping they spawn. I've sunk three big cedar trees, thinking that they will work. Those YP look healthy to me.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
