Fish feed heavily on baitfish after turnover, but around what water temp do you start looking for bass to be moving towards wintering spots and becoming more sluggish?

Stupid questions on my part :-(

First off...can I assume you are in Illinois...and focusing on smaller lakes & ponds?
 
Shallow areas to avoid are ones with brown "dying" weeds...as they are consuming oxygen in the water...and no baitfish will be in the area.

Generally...just after turnover...fish can be scattered...but then become more "grouped up".

Turnover generally happens around 40* of water temp....which I'm SURE hasn't happened ANYWHERE in the Midwest YET IMHO

Water was 44 degrees in the a Minneapolis metro river on Friday and 42 degrees in northern Minnesota over the weekend. NAFC Web Editor Jim Edlund and I fished river smallmouths and small-lake largemouths in 23 hours of fishing over three days. River smallies were holding near warmth-holding dark mudbanks (low water exposed the mud) and largemouth were holding on tree limbs that reached from shallow water (bank) and extended into 8 to 9 feet of water. Our largemouth pattern only yielded one here and one there though, so I think many had migrated to deeper staging areas, enroute to even deeper winte haunts. We did not find many at all in 12-15 feet deep weedlines and we did not try deeper water much though because the wind was 25 mph, so we had to stay close to tree lined shores to stay out of the wind -- my trolling motor could not hold us on deep-water spots. Shallow reeds and shallow submergent vegetation held no bass. Only good shallow water was shallow water with immediate access to deeper water, near trees and laydowns. Full trees with submerged branches were much better than single-log type laydowns -- Web Guy Greg

i'm having the same problem with the small lake i fish. its shallow with not a lot of weeds and i can not seem to find fish.
