26-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 23 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Bigelow Lake runs 26 acres with 0.8 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. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. You'll find it in Bulkley-Nechako Regional District. For a second option, Seymour Lake lies 1 mi southeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 7 to 23 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 16 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
