28-acre lake in Nipissing District, Ontario. The lake tops out around 10 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Cashel Lake maps at 28 acres behind 1.4 miles of shoreline, with a single island in the mix. With a 2 development index there's bank structure worth casting at, in moderation. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. It sits in Nipissing District. Its nearest charted neighbour, Clara Lake, is 1 mi to the south.
Spring brook trout on Cashel Lake hold shallow, usually 1 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 9 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
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 | 1 to 10 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 10 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 10 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: yellow perch sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 9 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. If you only fish one area, make it Break off the point: a drop-off around 4 ft that scores prime in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (4 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 10 ft chart-limited; documented 8 to 25 ft | midday & dawn | Break off the point (4 ft) | Jerkbait, Blade bait |
| Winter | 3 to 10 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (4 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. As the season builds they drop to 2 to 10 ft, wintering in 3 to 10 ft. Top water on the chart: Deep basin, a deep basin in the 9 ft range, prime in winter. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.

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

| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 3 to 10 ft chart-limited; documented 4 to 14 ft | dusk & dawn | Break off the point (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft chart-limited; documented 6 to 18 ft | dawn | Deep basin (9 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, brown bullhead slide up into 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 9 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.

Cashel Lake is about 10 ft (3 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey).
Anglers target brook trout, yellow perch, smallmouth bass, pumpkinseed, brown bullhead on Cashel Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Deep basin is the top-rated area: a deep basin in about 9 ft of water that rates prime for yellow perch in fall. The map above holds the full rated-spot list for every species and season.
For brook trout, 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.
Fishing on Cashel Lake is regulated by the Ontario fishing regulations (FMZ summary). Check the official Ontario regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
