344-acre lake in Ontario. The lake tops out around 23 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Moon River Bay runs 345 acres with 10.7 miles of edge, with 30 islands in the mix. That shoreline is heavily fingered (development index 4.1) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 87% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.3 mi end to end and 1.3 mi across at its widest. For a second option, Woods Bay lies 2 mi northwest.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 7 to 23 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 22 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 23 ft | dawn & dusk | Deep basin (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |

The spring pattern is a shallow one: lake trout in 6 to 23 ft. The depth story barely changes: 7 to 23 ft through summer, 6 to 23 ft in winter. Top water on the chart: Deep basin, a deep basin in the 22 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 23 ft | dawn & dusk | Break off the point (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Winter | 6 to 23 ft | dawn | Deep basin (22 ft) | White tube jig, Airplane jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 6 to 23 ft; cold water stacks them in 5 to 23 ft. Top water on the chart: Break off the point, a drop-off in the 15 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.

Spring brown trout on Moon River Bay hold shallow, usually 3 to 23 ft. Depth-wise the year is flat: 7 to 23 ft in summer, 3 to 23 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).

| Winter | 3 to 23 ft | dawn | Break off the point (15 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: landlocked salmon sit in 1 to 15 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 6 to 23 ft. Top water on the chart: Deep basin, a deep basin in the 22 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + streamer down deep or a thin spoon on lead core until the fish tell you otherwise.

Start shallow in spring: chinook salmon sit in 3 to 23 ft that time of year. They don't go far with the seasons — 7 to 23 ft covers summer, 7 to 23 ft covers winter. The spot to know is Deep basin, a deep basin in about 22 ft of water that rates prime for chinook salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a flasher + fly (green/white) or a magnum spoon on downrigger until the fish tell you otherwise.
