237-acre lake in Waukesha County, Wisconsin. The lake tops out around 36 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lower Nemahbin Lake runs 238 acres with 6.1 miles of edge, broken up by 2 islands. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 78% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 1.2 mi end to end and 0.7 mi across at its widest. You'll find it in Waukesha County. For a second option, Bowron Lake lies 1 mi west.
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 11 to 36 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for fall. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (16 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 36 ft | dusk & night | Break off the point (16 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 36 ft | dusk & dawn | Deep basin (31 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Lower Nemahbin Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

|---|---|---|---|---|

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
