328-acre lake in Nipissing District, Ontario. The lake tops out around 23 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
On the chart, Perchfin Lake draws 329 acres inside 5.4 miles of shoreline — 2 islands included. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 79% of this chart, as modeled. The basin spans about 1.1 mi end to end and 1 mi across at its widest. You'll find it in Nipissing District. For a second option, Mitchell Lake lies 2 mi northeast.
Spring yellow perch on Perchfin Lake hold shallow, usually 3 to 12 ft. They move out to 7 to 23 ft in summer and finish the year down in 7 to 23 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
