61-acre Deep Bay Harbour fishing map with contributor-qualified CHS NONNA survey contours (95.74% measured, 95.74% assessed), four measured spots, regional DFO salmon and herring evidence, harbour moorage and a private public-use ramp, and current Area 14, CSSP and adjacent-RCA guidance. The water tops out around 75 ft. The depth chart comes from CHS bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 60 acres of water rimmed by 1.4 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 65% of the water is 15 ft or less, the band where the food chain lives. Figure 0.5 mi of water from one end to the other, 0.4 mi at the beam. The nearest mapped water is Graham Lake, 4 mi to the north.
In spring, pacific chinook salmon run shallow here, mostly 19 to 75 ft. Summer keeps them at 10 to 75 ft, and they winter in 21 to 75 ft. Winter pacific chinook salmon concentrate at Deep Bay Harbour western basin, a prime-rated deep basin around 75 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a herring or sand-lance spoon or a baitfish hoochie behind a flasher most summer days.

|---|---|---|---|---|
| Spring | 19 to 75 ft | dawn | Deep Bay Harbour central channel shoulder (57 ft) | Herring-pattern spoon, Three-to-four-inch baitfish swimbait |
| Summer | 10 to 75 ft | dawn & dusk | Deep Bay Harbour central channel shoulder (57 ft) | Herring or sand-lance spoon, Baitfish hoochie behind a flasher |

The spring pattern is a shallow one: pacific coho salmon in 10 to 70 ft. Midsummer fish sit out in 8 to 75 ft before dropping to 23 to 75 ft for winter.
