McCarthy Lake Fishing in Ashland County, Wisconsin

• Overview

  McCarthy Lake is one of the Ashland County waters in Wisconsin. The setting is rolling bush on every side. Around 43 acres of surface means several distinct areas to work. Nearest town is Hurley, 20 miles off. Saint Paul sits 155 miles out, and it is the nearest city worth the name. A county boundary sits nearby, which can matter for local access rules.

• Where to Fish on McCarthy Lake

  The records we hold are silent on depth, so plan to find it yourself. Where the bottom changes texture, fish gather; find that line. Read the surface for the wind lane, then fish the edge of it. County-wide records name rainbow smelt, yellow perch, white sucker, johnny darter and brown trout. County data is a starting point rather than a guarantee. Read McCarthy Lake for ten minutes before the first cast goes out.

• Seasonal Patterns

  Averages move between 10°F in January and 65°F in July. Winter shuts the surface down for months. The freeze runs deep into the year, with break-up near mid April. Ice clears near mid April and comes back about late November in a typical year. The shoulder weeks of the open season are the productive ones. On McCarthy Lake that shapes the whole year.

• Tackle & Baits

  Nothing in our records says who may fish here. Access points are not mapped for this water, which suits people who like quiet. For the trout, small spinners and a box of nymphs cover both approaches. Some banks are open only from a marked point. Some ground is open by custom rather than by right, so tread carefully. Should this one be busy, Maki Lake is 0.7 miles off. Treat McCarthy Lake as unsettled until someone local tells you otherwise.
