94-acre lake near Lake County. The lake tops out around 14 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Minnesota DNR survey of 1973, a decades-old survey (the DNR's original lake-survey map). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 94 acres, worked by 2.5 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 1 mi with a 0.4-mi widest point. Lake County claims this one. Its nearest charted neighbour, Frog, is 1 mi to the north.
Start shallow in spring: walleye sit in 4 to 14 ft that time of year. They don't go far with the seasons — 4 to 14 ft covers summer, 4 to 14 ft covers winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for walleye in winter. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 14 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 14 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 14 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 10 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Spring northern pike on Trident hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

| Winter | 4 to 14 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Spring smallmouth bass on Trident hold shallow, usually 3 to 12 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. The chart's best answer is Main-lake point — point, 1 ft, good for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

| Winter | 4 to 14 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (1 ft) | Blade bait, Hair jig |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter rock bass. Plan around the evening in the warm months. A ned rig (small) or a marabou jig covers the summer program.

Spring bluegill on Trident hold shallow, usually 1 to 6 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
