Rating depth structure for burbot.
Recent public catches load as you reach this section.
15-acre lake in Timiskaming District, Ontario. The lake tops out around 48 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 1975, a decades-old survey (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 15 acres, worked by 0.7 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. About 75% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. Timiskaming District claims this one. Lockie Lake sits 0 mi south — the closest neighbouring chart.
Spring burbot on Holden Lake hold shallow, usually 14 to 48 ft. Depth-wise the year is flat: 14 to 48 ft in summer, 12 to 48 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 38 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
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 | 14 to 48 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (38 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 14 to 48 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (38 ft) | Heavy jig + cut bait |
| Fall | 14 to 48 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (38 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 12 to 48 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (38 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
