21-acre lake in Haliburton County, Ontario. The lake tops out around 17 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Little Louie Lake runs 21 acres with 0.7 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. 92% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The water lies in Haliburton County. Closest neighbour on DepthScout: Louie Lake, 1 mi east of here.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 17 ft, and by winter most fish are in 5 to 17 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 17 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 17 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |

Spring pumpkinseed on Little Louie Lake hold shallow, usually 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 5 to 17 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (14 ft) | |
