Well, the July swoon is upon is. Walleye fishing is getting pretty tough on Lake Wissota. With a free day on my hands, I resisted the urge to chase smallmouths as well as the temptation to stick with my usual routine. I decided instead to break out of my comfort zone and think outside of the box in an effort to scratch out a few Wissota walleyes.
First on my agenda was to hunt for some suspended eyes. In a normal year (one with reasonable amounts of rain), Wissota tends to not stratify (at least that’s what the Lindners claim in their books) because the flow through the reservior system lends itself to good mixing of the thermal layers. Well, we’ve got one dry year on our hands, and I had heard through the grapevine that the lake had stratified and that walleyes could be had just above the thermocline. So, off to find the thermocline I went.
Took me a bit but I did find it. It’s deep. You’ll see it pretty obviously in the photo above, in the high 30s to near 40 ft. This is limited to the original river channels that cut through the main body of the reservoir. I wasn’t able to find the thermocline on any of the other areas of the lake I checked.
Although I found the thermocline, I wasn’t able to find any walleyes associating with it. So, time for plan B.
