Soft grey light all day today, with light air out of the NNW and steady pressure. The fish at Big Lake are likely to sit near reed fringes and open pockets. Plan around the stretch from the day. Keep moving until you find them. Autumn fish are feeding up and less fussy than in summer.
The bites are excellent now
Night
Big Lake falls in Polk County, part of Wisconsin. Land around it is lake country bush. This is a pocket water of some 22 acres, and every part of it is reachable from the bank. The closest town, Luck, is 6.2 miles distant. Further out sit Frederic (8.9 miles) and Turtle Lake (15 miles). It sits well inside its county, with no border complications.
We hold no depth figure for this one. Where the bottom changes texture, fish gather; find that line. This is a lake, so the margins and the first drop matter most. Records held for Polk County cover brown trout, rainbow trout, northern pike and largemouth bass. These are county-wide records, so not all of them will be in this water. Anyone new to Big Lake should walk it once before setting up.
Seasonal averages run from 10°F in January up to 69°F in July. Seasons are distinct, and each one fishes differently. Look for the thaw near mid April; the fishing lifts straight after. From about mid April to around late November, expect open water on the long-run figures. The first weeks of open water and the last are the ones to plan for. Keep it in mind when planning a trip to Big Lake.
Nothing in our records says who may fish here. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A landowner's word beats anything printed elsewhere. Fishing rules and camping rules are set separately here. Vincent Lake, 0.9 miles away, makes the obvious fallback. Check the position at Big Lake before loading the car.
