Seven years later for high, muddy water, cold or warm , I believe even more in lures that thump, vibrate and push water . Over sized lures be they cranks, bladed baits, plastics , minnow baits etc all push a lot of water and get the fishes attention. Obviously you need to use lures suitable to the current and cover . In regular sized lures , I prefer plastics with action tails of some sort although in colder water cigar types and erie darters have done me well. Tubes are always a good choice even though I don't use them any more. I tend to go a bit more oversize with hard baits but with regular sized ones lures like wiggle warts or square bill cranks get the call more often. Chatterbaits have come back into the rotation , especially tipped with a thumper tail. . Replacing skirts or tipping spinnerbaits with 5 or 6 inch twisters or thumper tails[aka swimbaits] is another thing I like. In shoreline related slack areas pounding the bottom with heavier jig/pigs has worked at times.
In low, clear water, clear or translucent lures are a good choice . After experiencing a few drought years , I like areas with faster and more oxygenated flows even more .
On the cricks I fish in low, clear water, I have gone back to smaller lures like wee rebel craws , size zero/ one spinners, crappie sized spinnerbaits and one to two inch plastics or small Charlie brewer slider stuff . I have come to the conclusion that at least on my local cricks that there just were not enough really large fish to warrant bigger lures. Well outside of the spawn and I don't fish the cricks for smallmouth then, any way .
That and generally for me crick fishing is just about solitude and feeling a tug on the line , be it chub, sunfish, crappie, rock bass or smallmouth any more .
As far as the bluebird day stuff, I still think the main effect is to bring shade or faster, choppier water into the mix more. At least I have more confidence going that route . Bridges can be a real blessing . Fishing the shady side of cover can be just as important as over head shade .
