Fished a lake that has largemouth and smallmouth,fished the first day for largemouth.Tried 3-8' depths early and then deeper water,sunken trees,points after 11am till 1pm.Thru cranks,jigs,worms,C-rig with ringworms and 5" power jerk shad and Nada,nothing,no bass(one 8lb walleye on a chomper spider jig)The next morning we were at the dam trying for smallies,no topwater bite,nothing on crankbaits,nothing on tubes,triesd the C-rig with the 5" jerk shad and they would bang it once and no way to get a hookset,tried smaller hooks,bigger hooks and still the same results, one big bang and no fish.Switched to spinning tackle and C-rig with lighter line,lighter weight,got 2 fish and lost both before they got to the boat,kept trying for 2 hrs and gave up,frustrated.Am going back to same lake,what should we do differently?Water was 78* air temps ranged from 60am to 90 daytime,no breeze at all both days,water was 1' visibility,cloudy/slight algae bloom,3 class sizes of shad swimming in schools meaning they have alot to eat.Ok Guru's, all ears on this side of the screen
