During the next few years a few other waters were opened. In 1964, all waters in seven northwestern counties as well as Racine County were opened. In 1970, many waters larger than 500 acres were added, except for muskellunge waters. Motor trolling has been a matter of discussion in Wisconsin for many years. There are differences of opinion regarding the sporting aspects of this angling method and its effect upon fish populations.
Many people believe trolling depletes fish populations.
In some lakes, motor trolling has increased user conflicts because of the increased acreage used by trollers. We have evaluated muskellunge, northern pike, and walleye angling success for anglers casting or still-fishing versus anglers trolling. DNR has attempted to address the issue of trolling from a biological perspective. We have made several proposals over the years to allow trolling at public hearings held each year in every county of the state on the same night in April. At these meeting a slight majority of anglers remain opposed to trolling.
