13-acre lake in Renfrew County, Ontario. The lake tops out around 32 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 1976, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Little Garvin Lake maps at 13 acres behind 0.7 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. 82% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. It sits in Renfrew County. Garvin Lake sits 1 mi northeast — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Deep basin. It's a deep basin holding about 29 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (5 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 6 to 32 ft. If you only fish one area, make it Shoreline break: a drop-off around 5 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline break (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shoreline break (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 32 ft | dawn & dusk | Deep basin (29 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 32 ft | dawn | Shoreline break (5 ft) | Jigging spoon, Tube jig (white) |
