Fishing at Tree Lake, Marathon County, Wisconsin

• Overview

  Out in Marathon County, Wisconsin, sits Tree Lake. Everything around it is pine and birch. The water covers some 73 acres, so pick a bank rather than trying to cover it all. A shoreline of some 1.3 miles keeps the choices simple. For a base, Bevent sits 8.8 miles out. The nearest city of size is Green Bay, 63 miles away. The boundary is close enough to be worth checking before you fish.

• Where to Fish on Tree Lake

  Open data we checked carries no depth for this water. A soft bed grows weed late into autumn, which keeps fish shallow. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Marathon County include brown trout, common carp and yellow perch. The list covers the county rather than this water alone, so treat it as a guide. The near bank of Tree Lake is often the one people ignore.

• Seasonal Patterns

  Long-term averages put July at about 69°F and January near 13°F. Winter shuts the surface down for months. Ice-out usually falls in mid April, and the weeks after it fish hardest. The lid tends to go about mid April and return around late November. Early summer and early autumn carry the open-water season. On Tree Lake the same rules apply, with local timing.

• Tackle & Baits

  The paperwork position is blank for this one. Records list it as a natural water body rather than an impoundment. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Some banks are open only from a marked point. Barbless rules turn up on managed water more often than not. Penny Lake sits 0.2 miles off and takes the overflow. Treat Tree Lake as unsettled until someone local tells you otherwise.
