183-acre lake in Sudbury District, Ontario. The lake tops out around 39 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Hanover Lake runs 184 acres with 6.8 miles of edge, with 6 islands in the mix. The 3.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 45% of this chart. Figure 2.4 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Sudbury District. The nearest mapped water is Londonderry Lake, 3 mi to the southeast.
Spring lake whitefish on Hanover Lake hold shallow, usually 12 to 39 ft. Depth-wise the year is flat: 12 to 39 ft in summer, 12 to 39 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 36 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 39 ft | midday & dawn | Break off the point (16 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft | dawn | Deep basin (36 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (16 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 39 ft | midday & dawn | Deep basin (36 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 12 to 39 ft. If you only fish one area, make it Break off the point: a drop-off around 16 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (16 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 39 ft | dusk & night | Break off the point (16 ft) | Jigging rap, Jig + big minnow |
| Winter | 12 to 39 ft | dusk & dawn | Deep basin (36 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (16 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |
