5-acre lake in Parry Sound District, Ontario. The lake tops out around 12 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 1960, a decades-old survey (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lambs Lake runs 5 acres with 0.4 miles of edge. Nearly circular (index 1.1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. You'll find it in Parry Sound District. For a second option, East Tower L. lies 1 mi south.
When the water first warms, yellow perch slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 12 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 12 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 12 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 4 to 12 ft; cold water stacks them in 4 to 12 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Blade bait, Jigging spoon |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 4 to 12 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 4 to 12 ft | dusk | Deep basin (10 ft) | |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) |
