138-acre lake in Haliburton County, Ontario. The lake tops out around 79 ft. The depth data here comes from the Ontario MNRF survey of 1986 (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Goodwin Lake runs 138 acres with 4.6 miles of edge, broken up by an island. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 30% of the surface — that's where the groceries are. Figure 1.7 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Haliburton County. For a second option, Little Buckhorn Lake lies 1 mi west.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 24 to 79 ft, wintering in 20 to 79 ft. Top water on the chart: Deep basin, a deep basin in the 76 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 | 10 to 40 ft | dawn & dusk | Secondary point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 79 ft | dawn | Deep basin (76 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (16 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 79 ft | dawn | Deep basin (76 ft) | White tube jig, Airplane jig |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (7 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (76 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 20 to 45 ft. Secondary point is the standout, a point at roughly 16 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (5 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Secondary point (16 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (16 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (53 ft) | Blade bait, Hair jig |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 20 ft, then a winter hold in 12 to 30 ft. Start at Main-lake point. It's a point holding about 5 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (5 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (5 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Secondary point (16 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (76 ft) | Tungsten jig + plastic, Small spoon + spike |
