Comments8 to 12 we spotted didn't stay on surface very long, not to mention we have spotted these creatures occasionally in past years as far back as 20 years ago. We fish all over NE Kansas, but have only seen these at Lake Melvern. They always show up this time of year, usually mid day, when water is 80-83 degrees, in water clarity I'd consider dingy see 1/4 painted jig 12-18 inches below, usually in 12 to 20 Feet of water and typically on the south side of the lake.
