71-acre lake in Oneida County, Wisconsin. The lake tops out around 7 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Fish Lake runs 72 acres with 3 miles of edge. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 1.2 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Oneida County. The nearest mapped water is Fifth Lake, 1 mi to the north.
Early season walleye use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for winter. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

|---|---|---|---|---|
| Spring | 2 to 7 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Fish Lake is about 7 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target walleye, yellow perch, northern pike, muskellunge, smallmouth bass, largemouth bass, crappie, bluegill, pumpkinseed on Fish Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Deep basin is the top-rated area: a deep basin in about 6 ft of water that rates prime for walleye in winter. Open the map above to see every rated spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
