20-acre lake in Nipissing District, Ontario. The lake tops out around 11 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Loon Lake runs 19 acres with 1 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.4 mi of water from one end to the other. The water lies in Nipissing District. The nearest mapped water is Little Clear Lake, 1 mi to the south.
Start shallow in spring: brook trout sit in 1 to 11 ft that time of year. They don't go far with the seasons — 3 to 11 ft covers summer, 2 to 11 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 9 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 11 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 11 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 11 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 11 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season walleye use the shallows, holding in 3 to 11 ft. Even in summer they hold at 3 to 11 ft; winter keeps them in 3 to 11 ft. The chart's best answer is Break off the point — drop-off, 5 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 11 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 11 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 11 ft | dusk & dawn | Deep basin (9 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 3 to 11 ft, wintering in 3 to 11 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| 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) |

| Fall | 3 to 11 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 11 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: muskellunge in 3 to 11 ft. The depth story barely changes: 3 to 11 ft through summer, 3 to 11 ft in winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a double-10 bucktail or a topwater (walk-the-dog / creeper) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
