189-acre Secret Cove fishing map with contributor-qualified CHS NONNA survey contours (81.21% measured, 97.32% assessed), four measured spots, regional DFO salmon, herring and dogfish evidence, operator-confirmed transient moorage, and current Area 16, CSSP and adjacent-RCA guidance. The water tops out around 62 ft. The depth chart comes from CHS bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Secret Cove maps at 188 acres behind 8.6 miles of shoreline, with 5 islands in the mix. An index of 4.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 68% of the surface — that's where the groceries are. The basin spans about 1.9 mi end to end and 0.7 mi across at its widest. Its nearest charted neighbour, Trout Lake, is 4 mi to the southeast.
Spring pacific chinook salmon on Secret Cove hold shallow, usually 16 to 62 ft. Depth-wise the year is flat: 8 to 62 ft in summer, 17 to 62 ft once it turns cold. Put Turnagain entrance basin first on the milk run — a deep basin near 54 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a herring or sand-lance spoon or a baitfish hoochie behind a flasher.
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 | 16 to 62 ft chart-limited; documented 30 to 120 ft | dawn | Secret Cove central channel shoulder (50 ft) | Herring-pattern spoon, Three-to-four-inch baitfish swimbait |
| Summer | 8 to 62 ft chart-limited; documented 20 to 150 ft | dawn & dusk | Secret Cove central channel shoulder (50 ft) | Herring or sand-lance spoon, Baitfish hoochie behind a flasher |
| Fall | 6 to 62 ft chart-limited; documented 10 to 100 ft | dawn & dusk | Secret Cove central channel shoulder (50 ft) | Compact spoon, Baitfish spinner where legal |
| Winter | 17 to 62 ft chart-limited; documented 50 to 180 ft | midday | Turnagain entrance basin (54 ft) | Slow-trolled spoon, Deep baitfish plug |
Early season pacific coho salmon use the shallows, holding in 9 to 62 ft. Even in summer they hold at 6 to 62 ft; winter keeps them in 19 to 62 ft. Put Turnagain entrance basin first on the milk run — a deep basin near 54 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a small hoochie behind a flasher or a slim spoon and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 62 ft chart-limited; documented 10 to 70 ft | dawn & dusk | Secret Cove central channel shoulder (50 ft) | Small silver spoon, Slim baitfish fly |
| Summer | 6 to 62 ft chart-limited; documented 10 to 100 ft | dawn & dusk | Secret Cove central channel shoulder (50 ft) | Small hoochie behind a flasher, Slim spoon |
| Fall | 5 to 60 ft | dawn & dusk | Secret Cove central channel shoulder (50 ft) | Small spinner where legal, Compact spoon |
| Winter | 19 to 62 ft chart-limited; documented 30 to 100 ft | midday | Turnagain entrance basin (54 ft) | Slow small spoon, Compact trolling fly |
Come spring, look for lingcod tight to the bank in 11 to 62 ft. Through summer count on 7 to 62 ft; the winter hold is 16 to 62 ft. If you only fish one area, make it Secret Cove central channel shoulder: a channel edge around 50 ft that scores prime in fall. Best bite is midday and early morning. A heavy swimbait or a metal jig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 11 to 62 ft chart-limited; documented 25 to 140 ft | dawn | Secret Cove central channel shoulder (50 ft) | Heavy swimbait, Metal jig |

| Winter | 16 to 62 ft chart-limited; documented 60 to 240 ft | midday | Turnagain entrance basin (54 ft) | Heavy slow-pitch jig |
Early season surfperch use the shallows, holding in 2 to 18 ft. Expect a summer slide to 3 to 25 ft, then a winter hold in 6 to 35 ft. Put Secret Cove inner transition first on the milk run — a feeding flat near 10 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a 1–2 inch grub or a small paddletail and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | dawn | Secret Cove inner transition (10 ft) | Small grub on a light jig, Sand-crab imitation |
| Summer | 3 to 25 ft | dawn & dusk | Secret Cove inner transition (10 ft) | 1-2 inch grub, Small paddletail |
| Fall | 4 to 30 ft | dawn | Secret Cove inner transition (10 ft) | Small jig and grub, Compact spoon |
| Winter | 6 to 35 ft | midday | Secret Cove inner transition (10 ft) | Slow small grub, Light bottom jig |
