7-acre lake near Lake County. The lake tops out around 6 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Rat runs 7 acres with 0.5 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The water lies in Lake County. Closest neighbour on DepthScout: Flat Horn, 1 mi southwest of here.
Early season yellow perch use the shallows, holding in 2 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 2 to 6 ft. Put Shallow 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. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
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 6 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Time it for early morning and the evening. 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 6 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 6 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for rock bass tight to the bank in 1 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. Start at Shoreline break. It's a drop-off holding about 3 ft of water and rates prime come fall. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft chart-limited; documented 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 2 to 6 ft chart-limited; documented 5 to 20 ft | dusk | Shoreline break (3 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 6 ft chart-limited; documented 8 to 22 ft | midday | Shoreline break (3 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 6 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (5 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for pumpkinseed tight to the bank in 1 to 6 ft. Through summer count on 1 to 6 ft; the winter hold is 2 to 6 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.

Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 5 ft.
Season dates, license requirements, and size and bag limits for Minnesota waters are set by the Minnesota DNR — and special regulations can apply to Rat specifically, so confirm the current rules before you fish.

Rat is about 6 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike, rock bass, pumpkinseed on Rat.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. The map above holds the full rated-spot list for every species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
