Grimhs Lake in Polk County: How and When to Fish It

• Overview

  Within Polk County, Wisconsin, you have Grimhs Lake. This is rolling bush country. Surface area is around 33 acres, which gives you real water without needing a boat.

A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Grimhs Lake

  No depth figure has reached our records, which makes a plummet useful. Bays and points beat straight shoreline every time on water like this. Still water like this holds fish on the edges rather than out in the open. Records held for Polk County cover brown trout, rainbow trout and northern pike. Species recorded across the county may be limited to a few waters. Read Grimhs Lake before you fish it and the day goes better.

• Seasonal Patterns

  The warmest month averages 70°F, the coldest about 10°F. Spring and autumn carry the fishing; summer and winter test it. The lid usually sets by midwinter and gives way around early April. On average, early April opens the water and late November closes it again. May into June fishes hardest, and September gives a second good stretch before the lid returns. Time your trip to Grimhs Lake by conditions rather than dates.

• Tackle & Baits

  Nothing in our records says who may fish here. It formed naturally, so levels move with rainfall rather than with a gate. Public data shows nothing built here, so treat the whole approach as informal. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. A phone call first saves an afternoon. A polite question at the farm gate opens more banks than anything else. Grass Lake, 1 mile away, makes the obvious fallback.
