576-acre lake in Middlesex County, Ontario. The lake tops out around 35 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Fanshawe Lake runs 579 acres with 8.6 miles of edge. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 71% of this chart. Call it 2.3 mi long by 1.6 mi wide at the broadest reach. The water lies in Middlesex County. Closest neighbour on DepthScout: Pond Mills, 8 mi south of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Main-lake point is the standout, a point at roughly 5 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (34 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (6 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 7 to 35 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

It's a deep basin holding about 34 ft of water and rates prime come winter. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
