Bill are you just trying to get to next spring or are you wanting to establish a GS population? I would wait to add the GS as long as water temps allow this fall. The idea is to add them once the LMB slow down due to temps. This will allow the WE to eat more. Same if you try to add small BG.As Bill noted WE & YP will eat small GS and BG over winter. I would shoot for 4 inch GS and 3 inch BG. I have concerns on trying to establish GS long term with many hatchery raised GS. They are great for forage.
