56-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 14 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
Ada Lake maps at 56 acres behind 1.4 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. It sits in Muskoka District Municipality. If the bite dies, Butterfly Lake is 1 mi to the east.
Start shallow in spring: walleye sit in 4 to 14 ft that time of year. They don't go far with the seasons — 4 to 14 ft covers summer, 4 to 14 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 6 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 14 ft | dusk & dawn | Break off the point (6 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 14 ft | dusk & night | Break off the point (6 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 14 ft | dusk & dawn | Deep basin (12 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring northern pike on Ada Lake hold shallow, usually 2 to 8 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

Spring smallmouth bass on Ada Lake hold shallow, usually 3 to 12 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 14 ft | dawn & dusk | Break off the point (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. As the season builds they drop to 2 to 10 ft, wintering in 4 to 14 ft. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around the evening and early morning. A micro tube or a sponge spider (fly) covers the summer program.
