A little belated, but we usually go up there almost every sunday. Bass is decent, nothing large, Crappie are not monsters, they are pretty thin, bluegills are good, white/hybrid stripers are great, and yellow bass have overpopulated the lake. Last year someone pulled the number 2 state record striper from hardy. High 20s/low30 lbs. Alot of the time there is a DNR guy up at the ramp before noon takin surveys on fish caught. He always says there are ppl that run the channel and get their limit of good size crappie, but ive never seen em.
There is def better lakes, but I dont think ive gone to Hardy and not caught anything. If all else fails, you can fill your livewell with yellow bass.

Pulled these bad boys out recently
