45-acre lake near Cass County. The lake tops out around 29 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 1966, a decades-old survey (the DNR's original lake-survey map). Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 45 acres of water rimmed by 1.2 miles of bank. 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. 68% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. You'll find it in Cass County. For a second option, Sanborn lies 1 mi southwest.
Spring walleye on Fawn hold shallow, usually 4 to 15 ft. By summer they slide out to 9 to 29 ft, and by winter most fish are in 9 to 29 ft. The chart's best answer is Shoreline break — drop-off, 20 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
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 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 29 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Shoreline break (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 29 ft chart-limited; documented 12 to 40 ft | dusk & night | Shoreline break (20 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 29 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 9 to 29 ft game here, winter a 9 to 29 ft one. The chart's best answer is Deep basin — deep basin, 25 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 9 to 29 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

| Winter | 9 to 29 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline break (20 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 9 to 29 ft. Shoreline break is the standout, a drop-off at roughly 20 ft, rated prime for winter largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 29 ft chart-limited; documented 15 to 35 ft | midday | Shoreline break (20 ft) | Blade bait, Jigging spoon |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 9 to 29 ft. If you only fish one area, make it Shoreline break: a drop-off around 20 ft that scores prime in fall. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shoreline break (20 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (25 ft) | Tungsten ice jig + plastic, Tiny spoon |
