Your LMB are 1 yr. in place. You are in a northern climate. I bet you are on course to meet your goal. One key is have you seen any LMB fry . Yours may not spawn at 1 but wait until 2 (and or 10-12 inches). 50 LMB is good for an acre. Proper ranges are 30-100 depending on the goal and location. Check as per RC's suggestion. With your size LMB try a small jig with a real worm (or SS worm). They are there and I bet in good condition.
