All I usually target this time of year is Saugeye, got one today, and a couple yesterday. All of them have came on bright colored jigs (hot pink, orange, chartruese) with chartruese jigheads. Just give them something they can see, works real good with crappie too. Also when griggs/oshay get flooded (like they will be tomorrow) I find Crappie holding real tight way up in the brush piles, I'll catch them in chocolate milk/flood stage conditions, just lightly jigging brush piles, although it is a tad early for them to be super shallow.
