106-acre lake in Renfrew County, Ontario. The lake tops out around 26 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 1980 (an MNRF lake survey). What the data behind the map says about each species, season by season:
Lake Hardwood maps at 107 acres behind 2.7 miles of shoreline, broken up by an island. With a 1.9 development index there's bank structure worth casting at, in moderation. Call it 0.7 mi long by 0.5 mi wide at the broadest reach. It sits in Renfrew County. If the bite dies, Charlotte Lake is 1 mi to the north.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 | 8 to 26 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Deep basin (14 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 26 ft | midday | Deep basin (14 ft) | Blade bait, Jigging spoon |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
