Fishing Mercer Lake in Oneida County, Wisconsin

• Overview

  Mercer Lake stands in Oneida County, Wisconsin. Country round the bank runs to mixed forest. At 256 acres this is proper open water rather than a pond. Shoreline length is close to 4.0 miles, and each section fishes a little differently. It is among the larger waters listed here for Oneida County. Lac du Flambeau is the closest town at 8 miles. Green Bay sits 127 miles out, and it is the nearest city worth the name. The county line runs close by, so rules can change within a short drive.

• Where to Fish on Mercer Lake

  Nothing in our records gives a depth for this one. A natural lake fishes on cover, and cover here means weed and timber. Look for the band where the shallows give up and the bottom falls away. Public occurrence data for Oneida County names brown trout, walleye and largemouth bass. The county figures include rivers and lakes alike. At Mercer Lake light and wind decide more than tackle does.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 66°F, while January sits near 9°F. Winter closes the water for a while, and the reopening is worth catching. The lid usually goes in mid April, which opens the strongest weeks of the year. The water is typically free of ice between mid April and late November. The shoulder weeks of the open season are the productive ones. That shapes the year on Mercer Lake.

• Tackle & Baits

  No public source sets out the position on this bank. This is a natural basin, not a dammed one. The water sits inside or beside a nature reserve, so expect extra rules. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules differ from one water to the next round here. Some water is controlled locally without a sign saying so. For a change of water, Scotchman Lake is 1.3 miles distant. Check the current arrangement for Mercer Lake.
