1,109-acre lake in Sudbury District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Lang Lake draws 1,114 acres inside 27.5 miles of shoreline — 9 islands included. A development index of 5.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 44% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 7.9 mi long by 1 mi wide at the broadest reach. You'll find it in Sudbury District. For a second option, Deerhound Lake lies 1 mi northeast.
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is an 18 to 60 ft game here, winter an 18 to 60 ft one. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (11 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 60 ft | dawn | Deep basin (60 ft) | Blade bait vertical, Small jigging spoon |
