210-acre lake in Timiskaming District, Ontario. The lake tops out around 15 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Sydney L. draws 210 acres inside 9.6 miles of shoreline. With a shoreline index of 4.7, this water is all arms and coves — edge habitat well beyond its acreage. Figure 4.2 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Fraser L., 4 mi northeast of here.
When the water first warms, walleye slide up into 4 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 5 to 15 ft. If you only fish one area, make it Break off the point: a drop-off around 7 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 (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 15 ft | dusk & dawn | Break off the point (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 15 ft | dusk & night | Break off the point (7 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 15 ft | dusk & dawn | Deep basin (13 ft) | Jigging spoon + minnow head, Rattle bait |

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

The spot to know is Shallow bay flat, a weed flat in about 3 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.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
