9-acre lake in Renfrew County, Ontario. The lake tops out around 18 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Pats Lake draws 9 acres inside 0.5 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 92% of the surface on the model — that's where the groceries are. The water lies in Renfrew County. For a second option, Fergusons Lake lies 1 mi southeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 3 to 18 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 18 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 5 to 18 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
