Dive report for 5/9/26
- Visibility
- 10 feet, 15 feet in the shallows (low tide)
Nice vis in top 60ft but dark and silty below. Calm and crowded on surface. Did a pass at 90-100ft and found one tiny yelloweye rockfish, small wolf eel, school of 8 canary rockfish, and many small yellowtails. Up higher was sunny crimson anemones, cucumbers, scaled crabs, many nudis. Guy with a drone in parking lot showed me a dead gray whale on the far side of the island that I didn’t see.
Dive report for 4/10/26
- Visibility
- 10-15 feet
Decent vis just after high tide. Not many fish but about 5 tiny yoy rockfish. Large Puget sound king crab. 5 candy stripe shrimp with two having the parasitic isopods. Couple massive scaled crabs. Nearly no bull kelp when I remember a lot just a couple years ago.
How deep? I think I remember getting to 49m/160ft before a silt slope and seeing a couple canaries on the way (2024 Aug)
You're right - more fish deeper and sometimes canaries 80+. This dive I was max 65ft. More crimson anemones and candy stripes in the 45ft range.
So sad about the whale 🐳🌊🤗 sounds like a fun dive 🤩
