403-acre lake in Renfrew County, Ontario. The lake tops out around 60 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 405 acres of water rimmed by 7.6 miles of bank. The 2.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 55% of the surface on the model — that's where the groceries are. The basin spans about 2.4 mi end to end and 0.6 mi across at its widest. You'll find it in Renfrew County. For a second option, Big Rat Lake lies 2 mi northwest.
Spring yellow perch on Maskinonge Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
