Prior to providing my data I took a closer look at their analysis of data submitted for prior years. Surprisingly their data shows Wisconsin winter losses running at about 19% in the 2016-2017 winter season. To me this seemed out of touch with the reality experienced by hobbyist Wisconsin beekeepers. Looking a little deeper into the results it appears their analysis is driven by submittals by commercial beekeepers that do NOT winter their bees in Wisconsin. Their data showed 85% of hives were wintered elsewhere; definitely not something a hobbyist beekeeper does.
Even if a lot of hobbyist beekeepers were to submit data I feel the commercial beekeeper data will always swamp our small numbers.
Other links show the prevalence of the various bee viruses in Wisconsin. It appears that 8 out of 10 viruses are present in Wisconsin.

I did the full survey, and you're right, there should be data for bees wintered in Wisconsin, and a hobbyist category would be more informative.
