Mars Lake in Oneida County: How and When to Fish It

• Overview

  Mars Lake lies in Oneida County, Wisconsin. It sits in rolling bush. It measures about 40 acres, which is a comfortable size for bank fishing. There is roughly 1.3 miles of shoreline here, which is a short walk end to end. Nashville sits 7.9 miles from here and is the nearest stop. Rhinelander is 13 miles and Crandon 13 miles. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Mars Lake

  Depth is unmeasured here, so let the shoreline guide you. This is a lake, so the margins and the first drop matter most. Read the surface for the wind lane, then fish the edge of it. Oneida County records list brown trout, walleye, largemouth bass and northern pike among the fish reported. Records at this level tell you what is in the area. On Mars Lake that means starting tight and working out.

• Seasonal Patterns

  Climate normals give 66°F for July and 10°F for January. A solid cap is the normal state through winter. Count on hard cover from midwinter, and open water from mid April. On the long-run averages the water opens up around mid April and starts locking again about late November. The strong weeks are the first after break-up and the last before the freeze. Mars Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  No access rule appears in what we hold. No dam controls it, and the level follows the season. There is a launch about half a mile from the bank. Parking sits half a mile out, which makes for a walk with tackle. There is a pier recorded roughly half a mile away. Where access is informal, keep it that way by behaving. Signs go up and come down, so check on the day. Should this one be busy, Venus Lake is 0.3 miles off. None of that is settled for Mars Lake in what we hold.
