Keeping an open mind, check different types of structures with different bottom contents. Pay particular attention to tiny details, like the size of the rocks below or the density of the brush or weeds. Explore different depths. Often as not, the fish are still in the vicinity but have moved from shallow water to deeper water or vice versa. A big wind will often move fish shallower while several days of calm weather can drive them deeper.
Forage is nearly always the motivating factor when fish move.
Under certain conditions, fish will switch to forage choices briefly. A mayfly hatch in spring, for instance, may prompt walleyes to abandon the perch and gorge themselves on insects emerging from a mud flat. It's not important that weekend anglers understand exactly what's happening or why. What is important is that you keep huntin' and peckin' until you find the fish. Kris' Kitchen .
