77-acre lake in Timiskaming District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 2003 (an MNRF lake survey). Species by species, here's what the data says the year looks like.
On the chart, Nelson Lake draws 77 acres inside 2.7 miles of shoreline. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 85% of the surface — that's where the groceries are. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. The water lies in Timiskaming District. For a second option, Sullivan L. lies 2 mi south.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
