10,010-acre lake near Nisswa. The lake tops out around 80 ft. The depth data here comes from the Minnesota DNR survey of 1954, a decades-old survey (the DNR's original lake-survey map). Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 9,876 acres wrapped in 41.9 miles of bank, broken up by 6 islands. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 28% of this chart. Figure 8.9 mi of water from one end to the other, 3.9 mi at the beam. Cass County claims this one. Agate sits 1 mi northwest — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Sharp break, a drop-off in the 40 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (3 ft) | 1/8 oz jig + minnow, Hair jig |

Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Back-bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
