By Cold Feet Diver

Visibility: 15-20 feet, 5 feet in the shallows

1st dive 1010, 2nd dive 1230, no current, 48F vis: hazy 5 ft in the shallows, gradually opens up to 15ft-20ft below 60ft No crowds today. At the deep wall there was a red brotula hiding in the rocks, several large frosted nudi, a grunt sculpin, and rock fish. In the shallows saw an octo and a young adult wolf eel swimming around. At the south wall we saw a giant nudi, dog fish, several lingcod, more curious rock fish, and a toad fish.

Phenomenal dive along the south wall. Couldn't see much above 30ft but below that (and below the thermocline) plenty of viz. Gentle flooding current carried us past the wall at 40-60 ft and it was easy to swim home against it at about 30 ft. Saw FIVE GPOs hanging out in their various crevices, seven wolf eels poking their heads out, a school of maybe 30 rockfish (including a dozen juveniles) and a yellow nudibranch so big my buddy though it was a sponge at first!

Visibility: A clear 40+ feet, 5 feet in the shallows

Great stuff at depth, some of the best I’ve seen in recent memory for vis. Lots of leatherbacks, some massive starfish besides (a few feet from foot to foot tip) Several GPOs and schools do large rockfish, sunflower stars, nudis (dorids 3-6” max) ling cod of decent stature, and some fun greenlings. Folks reported a 6 gill about 4m long - buggers avoid me still but worth noting!!

Dive report for 9/5/25

Visibility: A clear 15 feet, <5 feet in the shallows (incoming tide)

The top 30 feet are very opaque and brownish, opening up pretty nicely to clear water at depth. There is clearly a Low Oxygen condition right now at the many wolfeels were often hanging out of their dens, torpid and breathing hard. A little sad. Otherwise a great set of dives with Wolfies, GPO's, giant squat lobsters (3-5 inches), and many Rockfish. Also, I saw 4 or 5 sunflower stars, including one very healthy one that was probably 20 inches in diameter. Compared against my 16-inch strobe arm.

Dive report for 9/8/25

Visibility: A hazy 15 feet, <5 feet in the shallows

Vis stayed bad all day long in the top 30fsw or so, but at times was 15-20 ft below that, with some cloudier and clearer sections. Watch read 11C at depth, and reads ~14C at depth around alki these days, so colder! Over 3 dives, saw at least a dozen sunflower stars, none wasting! 3 GPOS (one red too!), the gamut of wolf eels from battle-scarred, geriatric eels to one small orange juvenile, decorated warbonnet, a spiny lithoid crab, tons of yellow and white dorids (I've given up IDing white dorids) bethellas, one giant dendronotid.

I dove there the day before and I think we had identical dives! I saw all the same critters. :)

Dive report for 9/15/25

Visibility: A clear 20 feet, 15-20 feet in the shallows (high tide)

Excellent dives at Sund Rock today, despite multiple camera issues and a failed neck seal! Vis started out fabulous in the morning, both shallow and at depth, and got hazier and hazier throughout the day (I'd have put it at ~10 ft at depth by 3pm). Dendronotus iris still hanging out below the south wall, still blows me away. Also saw a dendronotus rufus, many yellow-margin cadlinas, nanaimo dorids, sandalwood dorids. Three GPOs seen. One rose star. One grunt sculpin. Lots of beautiful wolf eels. Big schools of rockfish on the edge of the fishbowl.

By Daniel Hershman

Visibility: A silty 10-15 feet, 5 feet in the shallows (outgoing tide)

Lots of animals outside of their hiding places, clearly there's a low-oxygen event going on. Lots of Wolf Eels, GPOs out and gasping... even the sea cucumbers were stressed. Quite a few Red Dendronotus nudibranchs, and more than a few medium-sized sunflower sea stars. Fish were gathered together in large schools in the shallows.

Visibility: A silty 30+ feet, <5 feet in the shallows

My two favorite dives of the year today! I feel so lucky to live half an hour from this site. There were two octopus in the open (I'm sure there were more if I had time to look), dozens of wolf eels in the open, hundreds of rockfish, thousands of shinerperch, large clown dorids, a giant dendronotus. It's clear there's a low O2 event, but the life seems a little less lethargic than previous years and the water is cooling down to 50F

Visibility: 20+ feet, 20 feet in the shallows (high tide)

nice visibility all the way down. Dropped in from the north wall entrance- but not at the bouy. swam out towards the deep to find three small walls of 15-20 feet of relief with the deepest one being 130-145' of depth. Visibility stayed nice throughout the water column. Low disolved oxygen event is very much affecting the marine life with the giant sea cucumbers having their white gills out. We found a handful of clutches of stubby squid eggs as well as a handful of skate eggs- I think these were all deeper than 90'. On the second dive, we found probably 15 wolf eels between 70-20' of depth. We had 2 sunflower stars per dive as well.

Two beautiful dives at Sund rock. the low 02 event is improving slightly. There are less wolf eels out, the octopus are back under their dens, and the sea cucumbers are starting to retract back to their normal state. Huge schools of baitfish and rockfish were swirling around the site. Dived with Milada, Bill, and Hilary!

I dove with mz53480 and visited the North Wall and Wreck. Visibility below 10fsw was very good (25ft). The crown of the North Wall aka Fish Bowl lived up to its name. It was alive with creatures, numerous schools of fish often too many to count. It was like a photo out of National Geographic.We also saw a very large GPO and the usual assortment of Wolf Eels. The Wreck has continued to deteriorate, but the hull remains. The very large Ling Cod (at least five) continue to stay in the area along with some very large rockfish. The sun came out and penetrated down to 45fsw making the dive even more enjoyable. Winter visibility is back. Now is the time to get in the water.

Amazing visibility at Sund Rock today. Still some sediment in the water, but such great clarity in spots (35+ feet)! There were several wolf eels in dens, including one juvenile in the fish bowl. 5 giant pacific octopus at North Wall and 2 spotted at South Wall. 4 healthy sunflower stars also. We even saw a vermillion rockfish at South Wall!

Did both the North and South. Splash for North wall around 8.45, South around 10.30. Vis was better on the North wall, just a little hazy at the top of the wall. Wolf eels, lingcod, painted greenling, nudi’s, so many. South wall vis was a little disappointing. But, did find a huge nudibranch, yet to be identified. At least 6 baby seastars.

Dove with mz53480 for about an hour. Water was noticeably cooler from surface to 15fsw. Visibility improved there to 30ft. Saw numerous Ling Cod, many protecting eggs. Also found three GPO, two were quite large. - so nice to have them back on the North Wall again. The usual contingent of Wolf Eels were present as well.

Vis was pretty nice (20+ ft) at 80fsw, and got progressively worse towards the surface, but at 30fsw it was still ~10 ft (the top 10 fsw were soup though). Very nice dives! Highlights for me included a grunt sculpin, skate egg, longfin gunnel, and an actively swimming giant dendronotid on the S wall (I think this same nudi has been there for 3+ months).

Cold and blurry in the fresh water layer at the surface - 47 degrees - Brrr. Mucky viz in the shallows, including Fish Bowl. Cleared up nicely at 40 feet and below. The wreck at the north buoy was clear and full of big Ling cod, some huge Black and Copper rockfish, and Painted greenling. We spotted a big Wolf eel on the north wall, along with a Sea lemon, Moon snail and several flounder. Others who went to the south wall saw at least 3 GPOs and 8 wolf eels. Considering the poor viz in the rest of the Sound, this was a good, if chilly dive.

Hi Kat.Willson, Do you happen to know if any of the GPOs were guarding eggs? Thank you and Happy Holidays, Brandon

Hi Brandon - I didn't hear anyone mention the GPOs guarding eggs. Happy holidays to you, too! Kat

Did both walls, and a trip to the wreck. tons of rockfish, found a nudi or two swimming across from the wall to the wreck. Vis in the fish bowl was better than expected. Dive buddy Mike spotted a baby sea star. The top few feet of water was interesting as the freshwater and salt water mixing gave a very hazy view. Southwall was a shorter dive, mostly around the 50-30 feet. Vis the same. Overall two great dives.

Dove both walls and the wreck. Consistently good visibility. Slightly better visibility on the south wall. Very cold freshwater layer with a distinctly visible halocline about six feet deep. Few wolf eels. No GPOs to be had today. Nice relief from all the grime in the central Puget Sound. Cheers ✌️

New Years Day event (thanks, YSS!). Dove South and North on separate dives. Substantial thermocline with 41F at surface and 50F at depth. Just a single baby sunflower star on each dive. Single adult Quillback Rockfish on the South Wall. Wolf eel under the block anchoring the buoy for North Wall, GPO just to the side in the rock pile.

Epic Giant Pacific Octopus encounter at Sund Rock

This octo was one of the highlights. I don't know if he was munching on something, looking to mate, or had recently just mated, but he wasn't much on the move!

Incredible dive with a GPO out in the open, a Giant Nudibranch, 4 sunflower stars, several wolf eels, and plenty of others. Perhaps the same GPO observed by others as he (?) was at ~45 ft halfway down the south wall and appeared largely apathetic. A little further, found a huge female tucked away behind a curtain of eggs. Viz was terrible down to 30’ and opened up decently below 40-50’
