61-acre lake in British Columbia. The lake tops out around 20 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 61 acres of water rimmed by 1.5 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 81% of this chart, as modeled. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. The water lies in Cariboo Regional District. For a second option, Donnely Lake lies 3 mi northeast.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. They don't go far with the seasons — 5 to 20 ft covers summer, 4 to 20 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
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 | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: kokanee in 6 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 5 to 20 ft in winter. The spot to know is Deep basin, a deep basin in about 17 ft of water that rates prime for kokanee in spring. Plan around early morning in the warm months. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (17 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 6 to 20 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (17 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 20 ft chart-limited; documented 5 to 40 ft | dawn | Deep basin (17 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 5 to 20 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (17 ft) | Small glow jig + corn or maggot, Tiny spoon |
Come spring, look for lake whitefish tight to the bank in 6 to 20 ft. Through summer count on 6 to 20 ft; the winter hold is 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 17 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (9 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (17 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (9 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (17 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: burbot in 6 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 5 to 20 ft in winter. Top water on the chart: Deep basin, a deep basin in the 17 ft range, prime in spring. Time it for after dark and midday. Summer baits: a heavy jig + cut bait gets it done.

Rat Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 17 ft down.
Season dates, license requirements, and size and bag limits for British Columbia waters are set by the BC freshwater fishing synopsis — and special regulations can apply to Rat Lake specifically, so confirm the current rules before you fish.

Rat Lake is about 20 ft (6 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 rainbow trout, kokanee, lake whitefish, burbot on Rat Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Deep basin is the top-rated area: a deep basin in about 17 ft of water that rates prime for kokanee in spring. The interactive chart above rates every spot for each species and season.
For rainbow 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 Rat Lake is regulated by the BC freshwater fishing synopsis. Check the official British Columbia regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
