Quadra Island, Abyssal Diving Charters

Discovery Passage's many world class dive sites have lured visitors since the early '80s when commercial divers first introduced visiting recreational divers to the water's secrets. Numerous articles that were since published in dive magazines and word of mouth have turned the Discovery Islands into true diving destinations for aficionados.

What's the secret to the beauty of our underwater landscape? Strong tidal currents. They provide food for abundant, unique marine life that simply can't survive in other waters.

Visibility in this high-current eco-system rarely drops below 10 metres due to constant upwellings of clear water. Quadra Island, Abyssal Diving ChartersSeasonal plankton blooms only occur in the top 10 to 15 metres and are quickly diluted by the upwellings. This creates excellent diving for north Pacific coastal passages in the summer, and in spring, fall, and winter the water is beautifully clear at any depth. Combine this with protected inside waters and mild weather, and you have the perfect location for a British Columbia diving adventure.

Currents flow through Seymour Narrows, the smallest portion of the 25-mile-long passage at speeds up to 15.4kts (Canadian Tide and Current Table). This is actually faster than Nakwakto Rapids which holds the Guiness Book record!

This current provides ample nutrients and oxygen to sustain a diversity of marine life, especially creatures that feed by filtering the water. Quadra Island, Abyssal Diving ChartersAn array of colourful anemones, sponges, tube worms, and other invertebrates compete for the available space and wait for food to come to them. In the cracks and crevices, wolf eels, huge lingcod, tiger rockfish, and the elusive giant pacific octopus find homes that are sheltered from the current. Varieties of colourful nudibranchs are too numerous to count. Close to the surface, huge schools of tiny fish find safety in numbers from spiny dogfish and salmon.

Harbour seals have taken up residence in Gowlland Harbour and are always curiously investigating visitors to the area. Near forests of bull kelp you'll find thousands of hungry sea urchins. A small island called Steep is also located in Discovery Passage. In her book 99 Dives, Betty Pratt-Johnson visited Steep and wrote, "Steep is one of those dives I label as having 'star' quality. Divers who want to visit the most special places in the world will want to go to Steep."

Quadra Island, Abyssal Diving ChartersScuba diving in most Discovery Passage sites can only be safely done during slack tide intervals. Approximately every six hours the current slows and finally reverses direction. Boats are manned at all times during the dive and ensure that other vessel traffic stays well clear of divers. Please note that times for slack tide and slack current are related — but different.

Row and Be Damned
Row and Be Damned, Quadra Island, Abyssal Charters drift diving

"Row and Be Damned" is rated one of Scuba Diving magazine's top 10 dive sites in all of British Columbia. It's also a favourite of divers no matter where they enter the current that carries them through a wealth of Pacific sealife. Without a doubt, Row and Be Damned is among the very best scenic, drift-diving experiences on the Canadian west coast.

Marine life here is truly abundant. Expect to see thousands of colourful corals, strawberry anemones, octopus, sponges, Puget sound king crabs, fish, and more fish.

Copper Cliffs
Copper Cliffs, Quadra Island, Abyssal Dive Charters

Cormorants, mule deer, and bald eagles can be seen atop and along the sheer wall of Copper Cliff which falls 300 feet into the Strait of Georgia. A hundred feet below the surface you'll find a series of ledges that ultimately drop off to the ocean floor.

Everything underwater is huge because of tidal exchanges, Puget Sound king crabs, schools of black rockfish, dogfish sharks, tiger and copper rockfish, red snapper, wolf eels, mosshead warbonnets, giant plumose anemones, orange cup corals, cloud sponges, feather duster tube worms, nudibranchs of many kinds, sea squirts, and curious seals.

HMCS Columbia
HMCS Columbia, Quadra Island, Abyssal Dive Charters

Our largest wreck, HMCS Columbia is a 2800-tonne, decommissioned, non-modified Restigouche class destroyer escort that was scuttled and sunk here on June 22, 1996 after more than a year of preparation.

This spectacular 366-foot vessel sits at a 35° list to port with the bow at a maximum depth of 120 feet, which was crumpled like an accordion when it hit the rocky ocean floor. The superstructure and wheelhouse reach approximately 60 feet to the water's surface. This allows divers to match skill and comfort level to the elevation of the ship's components.

More than 10 years later, HMCS Columbia has become a thriving artificial reef. Access holes had been cut to open up most of the interior's six decks to properly trained and equipped wreck divers, but we do not recommend penetration. Although the interior may seem sufficiently lit when divers arrive, sediment soon lifts and reduces visibility to zero, a common oversight of novice and experienced divers alike.

This might be one of the largest, most intact underwater wrecks you'll ever see. Unlike other current-swept sites in our area, this area is sheltered from the main current, allowing access at any time of day.

Whiskey Point
Whiskey Point, Quadra Island, Abyssal Dive Charters

A dive full of colour and life, with clean-swept rocks tiered from 30 to 90 feet, Whiskey Point is another favourite and one that shouldn't be missed.

Strawberry anemones, purple algae, tennis sponges, yellow encrusting sponges, snakelock anemones, giant barnacles, abalone, scallops, ling cod, red Irish lords, kelp greenlings, hairy cancer crabs, octopus and even visiting seals can all be seen here.

Steep Island
Steep Island, Quadra Island, Abyssal Dive Charters

Steep is a popular dive for visitors and locals alike. Here you'll dive among the "feather dusters", purple tube worms, an experience too fantastic to describe. Some are over three feet in diameter. On this dive you can reach depths of 120 to 130 feet.

Orange, yellow, and white sponges add a rainbow of colour to the dive. Cloud nipple and trumpet sponges are few of the sponges you'll see, rock scallops, swimming scallops, cabezon, ling cod, octopus, kelp greenlings, yellow-eyed rockfish (known as red snappers), and scally head sculpins are all denizens of Steep.

You can also find spiny dogfish sharks here, just as you will at several of our dives in the Quadra Island area. These have never been known to be man-biters, but their appearance can still be formidable, growing up to five feet in length at maturity.

April Point
April Point, Quadra Island, Abyssal Dive Charters

April Point is a terrific wall dive where you'll see tealia anemones, basket stars, funnel and cloud sponges, soft and hard coral, abalone, Puget sound king crabs, giant nudibranchs, and ling cod. Like any popular dive site in our area, April Point is highly picturesque and typifies the marine environment of the Pacific Northwest.

Argonaut Wharf
Argonaut Wharf, Quadra Island, Abyssal Dive Charters

The underwater "garden" at Argonaut Wharf is a haven for the giant Pacific plumose anemone, featured in National Geographic and numerous other publications over the years. The landscape here is covered with clouds of these beautiful plants, a site simply never experienced by non-divers and one that represents the beauty of fragile ocean plants that can reach hundreds of years in age when undisturbed.

The area also makes great night dive. At Argonaut Wharf it's easy to see decorator crabs, red or pink dahlia, and numerous fish including flounder, red Irish lords, and cabezon.

Grouse Island
Grouse Island, Quadra Island, Abyssal Dive Charters

This is a great dive no matter where you enter the water around the island's circumference. Look for wolf eels, octopus, Puget Sound king crabs, decorator crabs, colourful cup corals, sponges, plum anemones, sea lemon nudibranchs, abalone, crabs, scallops, shrimp, and yellow-eyed rockfish.

Ferry wreck
Ferry wreck, Quadra Island, Abyssal Dive Charters

Located off May Island, the ferry wreck is a nice, easy dive to end the day. Octopus live here around the wreck and along the shallow wall with brightly coloured cup corals, sponges, kelp greenlings, ling cod — and the odd golf ball you might collect as a souvenir from someone who apparently likes to practise his swing from topside.

Seymour Narrows
Seymour Narrows, Quadra Island, Abyssal Dive Charters

The highly planned removal of Ripple Rock in this area decades ago was the largest non-nuclear explosion in the world — and the riddance of one of the deadliest marine hazards in British Columbia.

Today tidal currents up to 16 knots race through this spot, so dives always take place on the slack tides. Rounded ledges start at 20 to 30 feet and then descend well below recreational dive limits. Among them, crevices and crannies abound to hide sealife from the current.

Lots of colour can be seen on this dive including white, Christmas, red snakelock, mauve and pink brooding anemones. You'll also see an abundance of yellow staghorn bryozoans, trumpet and orange ball sponges, chitons, giant red and green urchins, abalone, swimming scallops, kelp greenlings, and lingcod, all which benefit from the nutrients of the fast-moving tides.
