101-acre lake in Kenora District, Ontario. The lake tops out around 13 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 1987 (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
Gladys Lake maps at 102 acres behind 2 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Kenora District. Its nearest charted neighbour, East Godson Lake, is 1 mi to the west.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 4 to 13 ft; cold water stacks them in 4 to 13 ft. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 4 to 13 ft in summer and finish the year down in 4 to 13 ft. If you only fish one area, make it Back-bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

Deep basin is the top-rated area: a deep basin in about 10 ft of water that rates prime for yellow perch in fall. The map above holds the full rated-spot list for every species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
