34-acre lake in Nipissing District, Ontario. The lake tops out around 30 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Holts L. draws 33 acres inside 1.3 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 50% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. You'll find it in Nipissing District. The nearest mapped water is Pat Lake, 1 mi to the southwest.
Spring yellow perch on Holts L. hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |

When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.

The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for brown bullhead in winter. Plan around after dark and the evening in the warm months.

| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
