Fishing in Cowichan Valley Regional District, British Columbia

What this local map set contains

The Cowichan Valley Regional District directory currently covers 30 lakes or reservoirs. 6 charts use measured bathymetry from a published source; 24 charts are clearly labeled as modeled. Recorded maximum depths range from 6 to 499 ft, with a median of 26 ft. Those figures describe each chart's deepest recorded or modeled point, not a safe navigation depth.

Species records are attached to 30 of 30 waters. The most frequently cataloged targets are Rainbow Trout (29), Cutthroat Trout (21), Coho Salmon (15), Brook Trout (9) and Smallmouth Bass (6). These are coverage counts, not abundance estimates or catch forecasts; open the individual map to see the evidence and seasonal context attached to that water.

Three useful maps to compare first

1. Somenos Lake: 25 ft maximum; survey-backed contours; 7 cataloged target species.
2. Dimple Lake: 30 ft maximum; survey-backed contours; 3 cataloged target species.
3. Oliphant Lake: 26 ft maximum; survey-backed contours; 3 cataloged target species.

Start with a survey-backed chart when exact contour shape matters most. Use a modeled chart as broad planning context, then verify depths on the water. Comparing the three examples above also shows whether this area offers one dominant basin type or genuinely different shallow, deep, lake and river options. Access is separate from map coverage: confirm launches, shore rights, closures and posted rules before making the trip.
