Rating depth structure for rainbow trout.

5-acre lake in Marinette County, Wisconsin. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What the data behind the map says about each species, season by season:
The outline encloses 5 acres, worked by 0.4 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 56% of this chart, as modeled. It sits in Marinette County. If the bite dies, Little Newton Lake is 1 mi to the east.
Early season rainbow trout use the shallows, holding in 5 to 18 ft. Even in summer they hold at 5 to 18 ft; winter keeps them in 4 to 18 ft. Put Break off the point first on the milk run — a drop-off near 8 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
3 pieces of structure are mapped here — Deep basin, around 15 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Wisconsin waters are set by the Wisconsin DNR — and special regulations can apply to Medbrook Lake specifically, so confirm the current rules before you fish.

Medbrook Lake is about 18 ft (5 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 rainbow trout on Medbrook 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.
Break off the point is the top-rated area: a drop-off in about 8 ft of water that rates prime for rainbow trout in winter. The interactive chart above rates every spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Medbrook Lake is regulated by the Wisconsin DNR. Check the official Wisconsin regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
