Last spring was the first time I've ever fished the river at Heskett, near Mandan. I caught quite a few male walleye before sunset using a jig. However I never did catch anything but smaller males. I know the larger fish exist in that area because the night fishermen would catch them, typically using crankbaits. My question is where are these bigger fish located during the daytime in that area? They are obviously in the area because they are caught every night. Are they sitting farther in the main river and move shallow during the night? Just wondering if any of you have had any experience finding these larger fish during daylight. I know during spawning the females are more active during the night but its hard to believe that if they are in the area where I cast that none of them would bite at all during the day. I never saw a big fish caught during the day last year.
