    The part about the walleye size structure really caught my eye. 32% over 18″…..yippie! This certainly fits with my records of more and more fish over the slow limit showing up every year. Great news for the inaugural Lake Wissota Open Walleye Tournament sponsored by the WWWAA!

    Lake Wissota – Spring netting surveys conducted in 2006 and 2007 provided a population estimate of one adult musky for every 10 acres. The number of larger, older fish was low due to low stocking levels from the midto late 1990s. Fifteen percent of the catch was 40 inches and larger, with the largest a 54-inch female. In fall 2005, the local Muskies Inc. chapter stocked 500 Leech Lake strain muskies and added another 833 Leech Lake fingerlings in fall 2007. The 2007 musky survey also provided further information on walleye, northern pike and smallmouth bass populations. Thirty-two percent of the walleye catch was 18 inches and larger, which indicates that the 14- to 18-inch protected slot size is doing well at producing larger fish in the lake. For legal-size smallmouth bass, 23 percent of the catch was 17 inches and larger. Northern pike are more widespread throughout the lake compared to the 1989 survey. Little Lake Wissota and the Yellow River area of the lake now hold good numbers of northern pike with 19 percent of the 2007 catch 26 inches and larger.

    That is great news Jason, now if Kevin & I can find a couple 18″ or larger during the lake wissota open.

    Didn’t you tell me that the wissota fish have a slower growth rate than other fish?

    I was lucky enough to get to peek at Joe’s raw survey data. He has been seeing multiple fish in the 27-28+” class for each of the past two years.

    The big girls are there!

    This goes to show how great the slot is working on Lake Wissota. The bigger fish are making a comeback! As long as they keep the slot the way it is, and the daily bag at 3, we will continue to see improvement on Wissota walleye.

    I ran into a couple of wardens last year while they were doing their netting. The guy I talked to said that Wissota was one of the better all around lakes in Wisconsin, in terms of size and numbers. That is not only for walleye, but also for muskie, and smallmouth.

    I was just looking at the DNR’s 2006 estimates for ceded territory and those fish must have been put on super pills to have gotten that large so suddenly. The estimated Lake population was 13,017 that’s 2.1 fish per acre. 12 to 15 inch class is 1.2 fish/ acre. 15 to 20 inch class is 0.6/acre and over 20 inches is 0.1/ acre. Doesn’t seem that good to me and this is right out of the DNR files. I sure don’t want to leave people with a false impression of walleye populations but this seems a little careless.

    It’s my understanding that all those pike are bad for the musky population (pike eat musky fry). Is that correct? On the other hand, Joe Kurz said there isn’t much natural reproduction of musky in Wissota so it’s probably a mute point.

    I also understand (as in Nelson lake by Hayward) that LM Bass hurt walleye populations, but that doesn’t seem to be a problem. Maybe Wissota just doesn’t have that many LM bass – or their living areas don’t overlap much.

    There are certainly LMB in Wissota, but in my experience, they are localized in certain areas of the lake (the little lake, the yellow river arm) rather than being widespread like the eyes and smallies seem to be. So much of the lake is just not classic LMB water.

    Joe’s 2007 survey was by fyke netting….it was a musky survey that also provided some walleye sampling. As a result, it is biased towards adult fish.

    Perhaps a more accurate description of the results should be that a sampling of adults had 32% over 18″.

    The 2006 survey was done by both netting and shocking. That survey collected a total of 4306 fish. Of those, 308 (7.1%) were over 18″. 988 (23%) were slot fish. The balance were under the slot.
