6,720-acre lake near Lakefield. The lake tops out around 102 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
On the chart, Stony Lake draws 8,666 acres inside 77.5 miles of shoreline — 16 islands included. With a shoreline index of 5.9, this water is all arms and coves — edge habitat well beyond its acreage. 64% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 9.7 mi with a 3.5-mi widest point. You'll find it in Peterborough County. Closest neighbour on DepthScout: Dummer Lake, 2 mi southeast of here.
Spring lake whitefish on Stony Lake hold shallow, usually 15 to 45 ft. They move out to 40 to 90 ft in summer and finish the year down in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 99 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 4 ft that scores prime in spring. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Creek inflow (4 ft) | 1/8 oz jig + minnow, Hair jig |

Early season sauger use the shallows, holding in 4 to 18 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 45 ft.

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

Spring puts muskellunge in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 25 ft; cold water stacks them in 15 to 35 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for fall muskellunge. Plan around the evening and early morning in the warm months. A double-10 bucktail or a topwater (walk-the-dog / creeper) covers the summer program.
