48-acre lake near Crow Wing County. The lake tops out around 13 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Rock runs 48 acres with 1.3 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Crow Wing County. For a second option, O'Brien (Southwest Bay) lies 1 mi east.
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 4 to 13 ft; cold water stacks them in 4 to 13 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 13 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 4 to 13 ft; cold water stacks them in 4 to 13 ft. Top water on the chart: Deep basin, a deep basin in the 11 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 4 to 13 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Break off the point (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 13 ft chart-limited; documented 8 to 20 ft | dawn | Break off the point (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (11 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 3 to 13 ft before dropping to 4 to 13 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
