7,357-acre lake in Rainy River District, Ontario. The lake tops out around 260 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Agnes Lake maps at 7,356 acres behind 106.5 miles of shoreline — 65 islands included. The 8.9 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 22% of this chart. The basin spans about 14.5 mi end to end and 4.3 mi across at its widest. It sits in Rainy River District. Its nearest charted neighbour, Louisa Lake, is 5 mi to the south.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Offshore hump first on the milk run — an offshore hump near 24 ft that grades prime for winter. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (12 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 7 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Offshore hump, an offshore hump in the 24 ft range, prime in summer. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (7 ft) | 1/8 oz jig + minnow, Hair jig |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
