12-acre lake near Québec. The lake tops out around 26 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Lac Bonom runs 12 acres with 0.5 miles of edge. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 46% of the water is 15 ft or less, the band where the food chain lives. The water lies in Matawinie MRC. For a second option, Lac Dispos lies 0 mi east.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 8 to 26 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |

When the water first warms, walleye slide up into 4 to 15 ft. Summer is an 8 to 26 ft game here, winter an 8 to 26 ft one. Start at Shoreline break. It's a drop-off holding about 22 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
