Where I fish, bass and pike's ranges intersect in spring and fall. Since pike are the dominant predator, many of the top, cooler spots are seized as their territory, and bass are driven off. I've fished prime pike spots, and never caught a bass. I've fished other spots, not conducive to pike where it's nothing but largemouth. Conversely, while pike will drive off smallies, it's not unusual to catch both when fishing for either.
