28-acre lake in Parry Sound District, Ontario. The lake tops out around 7 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 1983 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 28 acres of water rimmed by 1.6 miles of bank — one island included. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.6 mi long by 0.2 mi wide at the broadest reach. The water lies in Parry Sound District. Closest neighbour on DepthScout: Wiwassasegen Lake, 2 mi northwest of here.
Early season yellow perch use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Deep basin first on the milk run — a deep basin near 7 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
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 | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Break off the point is the standout, a drop-off at roughly 7 ft, rated prime for fall northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

In spring, smallmouth bass run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Main-lake point is the standout, a point at roughly 4 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.

Spring puts largemouth bass in skinny water — 1 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 ft. Fall largemouth bass concentrate at Main-lake point, a prime-rated point around 4 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

Come spring, look for rock bass tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Main-lake point. It's a point holding about 4 ft of water and rates prime come summer. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

Come spring, look for pumpkinseed tight to the bank in 1 to 7 ft. Through summer count on 1 to 7 ft; the winter hold is 2 to 7 ft. Start at Deep basin. It's a deep basin holding about 7 ft of water and rates prime come winter. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.

Carling L. K4 is about 7 ft (2 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1983 (a transect sounding survey).
Anglers target yellow perch, northern pike, smallmouth bass, largemouth bass, rock bass, pumpkinseed, brown bullhead on Carling L. K4. 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 7 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Carling L. K4 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.
