72-acre lake in Sunshine Coast Regional District, British Columbia. The lake tops out around 108 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 72 acres of water rimmed by 1.9 miles of bank. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 41% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.5 mi long by 0.4 mi wide at the broadest reach. The water lies in Sunshine Coast Regional District. The nearest mapped water is Ruby Lake, 2 mi to the east.
Spring cutthroat trout on Ambrose Lake hold shallow, usually 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. Put Secondary point first on the milk run — a point near 7 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
