Fishing tournament participants represent a high risk category. I don’t think it is a coincidence that five of the six most recently infested zebra mussel lakes (Alexandria chain, Gull, Mille Lacs, Pelican and Minnetonka) are all in the highest prize category (greater than $10,000) of permitted fishing contests in Minnesota. These lakes are also very highly visited, but many other highly visited lakes do not have zebra mussels.
