Post 2010 Sturgeon Spearing Season Summaries

Attached are the initial summary reports from the 2010 Winnebago lake sturgeon spearing season including:

A great season. Definitely one for the record books. I want to once again thank all the sturgeon registration workers who faithfully and diligently gathered the data, and all the spearers who work so closely with us to make this one of the most unique and premier sturgeon fisheries on the planet. Looking forward to 2011!
Spring Walleye and Sturgeon Spawning Assessments

We’re gearing up in a big way for our spring assessments now – we expect to begin tagging some walleye next week already and to be full tagging mode on walleye on the upper Fox and Wolf Rivers before Easter. These data are critical to our walleye management program as they allow us to estimate annual walleye exploitation rates and densities on the Winnebago System. We have been annually tagging walleye on the upper Fox and Wolf Rivers since 1989 and have been able to use these data to effectively track, manage, and build the walleye population and fishery to the outstanding levels we experience today. The ice is out on both rivers now (went out on the Wolf yesterday – Tuesday 3/16) and anglers are already catching walleye on the upper Fox below Eureka and Princeton dams. We expect to see the pre-spawn fishing action picking up on the Wolf over the next week or so. The Wolf River Cam, run by a private enterprise out of Shiocton, is now up and running and can be viewed at The site offers underwater views of the walleye run, and later sturgeon spawning when that begins on the Wolf River.

Our sturgeon spawning assessment typically begins right on the heals of our walleye assessment – usually mid April. If you haven’t signed up for Sturgeon Guard yet and are still interested, our Sturgeon Guard Coordinator, Lisa Sharkey, is making out the schedule as we speak and can still get you in. Contact her at You can also call our Sturgeon Hotline at 920-303-5444 to reserve a spot in our sturgeon guard program, and to check on sites to see spawning sturgeon once they start. Usually the sturgeon do not begin spawning until after mid April so call the hotline around that time for a good tip on where to take the family to see this awesome spectacle of nature. You can also see this Wolf River sturgeon spectacle in all its grandeur in the film Mysteries of the Great Lakes produced by Science North and available as a DVD at

Till my next report……….
