Have the BG from last year spawned ? Do a seine survey and post results. If you have had several spawns by BG then you wont need 2000 more but it would not hurt if you want a LMB lake. Are you feeding ? FH addition would be good. I would stock 35 LMB per acre if that is your goal. 100 LMB pre acre is to many if you want large LMB. Newer data indicates that rather than 10 to 1 BG/LMB that for a LMB pond 30 to 1 will allow you to keep sufficient forage for an additional 2 years.
