794-acre lake in Nipissing District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Muskosung Lake maps at 797 acres behind 10.4 miles of shoreline, broken up by 4 islands. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 77% of this chart. Tip to tip the water measures near 2.6 mi with a 1.4-mi widest point. It sits in Nipissing District. Its nearest charted neighbour, Bain Lake, is 2 mi to the southeast.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 10 to 33 ft before dropping to 10 to 33 ft for winter. The spot to know is Deep basin, a deep basin in about 31 ft of water that rates prime for walleye in winter. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |
