Grenquist Lake, Wisconsin: Fishing Spots and Seasons

• Overview

  Grenquist Lake falls in Polk County, part of Wisconsin. The ground round it is rolling bush. With some 59 acres of water, there is room for a boat but no need of one. With about 1.5 miles of edge, you can try several depths in one session. Some 8.3 miles away sits Cumberland, the nearest settlement. After that come Turtle Lake at 12 miles and Luck at 14 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Grenquist Lake

  Without a survey to go on, judge depth from how the bank falls away. The productive water is a rod length or two out, not a hundred. This is a lake, so the margins and the first drop matter most. Fish documented in Polk County include brown trout, rainbow trout, northern pike, largemouth bass and bluegill. Records at county level tell you what is around, not what is stocked here. On Grenquist Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 69°F, while January sits near 10°F. Winter shuts the surface down for months. Hard water holds through the cold months, breaking up near mid April. Average temperatures cross freezing around mid April in spring and again near late November in autumn. The open run goes from the thaw to the freeze, and April through October covers most of it. That is the shape of the year on Grenquist Lake.

• Tackle & Baits

  Whether the bank is open is not something our records settle. It formed naturally, so levels move with rainfall rather than with a gate. There are toilets mapped about half a mile away. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking is often the real limit rather than the bank itself. A polite question at the farm gate opens more banks than anything else. Johnson Lake at 0.9 miles is the sensible second choice. Nothing here settles the position at Grenquist Lake for certain.
