259-acre lake in Leeds and Grenville United Counties, Ontario. The lake tops out around 40 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (an MNRF lake survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 258 acres of water rimmed by 4 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 71% of this chart. Figure 1 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Leeds and Grenville United Counties. The nearest mapped water is Red Horse Lake, 1 mi to the east.
Spring yellow perch on Singleton Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Break off the point — drop-off, 14 ft, prime for summer. Prime time lands in 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft.

A bucktail or a weedless spoon over cabbage covers the summer program.

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. Break off the point is the standout, a drop-off at roughly 14 ft, rated prime for winter largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
