39-acre lake near Cook County. The lake tops out around 52 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Copper runs 39 acres with 2.4 miles of edge. A development index of 2.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 57% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.8 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Cook County. For a second option, Missing Link lies 1 mi northwest.
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring puts burbot in skinny water — 16 to 52 ft is the zone. Summer fish stay in 16 to 52 ft, and winter fish hold in 13 to 52 ft. Deep basin is the standout, a deep basin at roughly 44 ft, rated prime for spring burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
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 | 16 to 52 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (44 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 16 to 52 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (44 ft) | Heavy jig + cut bait |
| Fall | 16 to 52 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (44 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 13 to 52 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (44 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Copper carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 44 ft down.
Season dates, license requirements, and size and bag limits for Minnesota waters are set by the Minnesota DNR — and special regulations can apply to Copper specifically, so confirm the current rules before you fish.

Shallow bay flat is the top-rated area: a weed flat in about 6 ft of water that rates prime for northern pike in spring. The map above holds the full rated-spot list for every species and season.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
