Day Island Wall

Day Island Wall is one of the best wall dives in Puget Sound. Spiny Dogfish Shark resting on top of the Day Island WallThe site is home to a large population of Wolf Eels and Octopuses that are comfortable around divers and frequently come out to play.  The site is in a high current area, so careful planning is required in order to have a safe, enjoyable dive during slack water. Diving this site during a large tidal exchange is just about guaranteed to give you a one-way ride down the Tacoma Narrows.
 
Day Island itself is just south of Titlow Beach in Tacoma.  Shore entry to the dive site is from a small public access beach.  Street parking is limited and the neighbors arenít crazy about all of the divers and traffic, so please be considerate.  I normally dive this site from a live boat, which makes timing the currents less critical, but it is a very popular shore dive as well.  To find the wall, swim out directly from the shore entry and youíll find the top of the wall in about 45í of water.
 
 The wall itself runs parallel to the shore, with the north end shallower (25' to 50') and the south end deeper (40' to 100'). There are numerous nooks and crannies along the wall that are dens to many wolf eels and octopuses.   Youíll also likely see dogfish, heart crabs, lingcod, as well as the usual anemones and sea stars.
 
Diver Janet Boyd examines critters on Day Island WallDuring a low exchange, when diving the slack before ebb (high tide), dive the South portion of the wall, entering the water 50 minutes before predicted slack (Narrows North).   If timed right, the current should gently carry you south, reverse and then carry you back north to the entry. The southern wall starts in about 50' and drops down to 100' in places.
 
When diving this site at slack before flood (low tide), dive the North portion of the wall, entering the water 50 minutes before predicted slack (Narrows North). The current should gently carry you north along the wall, reverse, then carry you back to the entry. The north portion of the wall ranges from around 25' to 50' deep.   There is also a nice boulder field just a bit deeper than the base of the wall as you head north, which is a great place to find lots of small and interesting critters.  However, if you are doing a long dive on the north wall, do be aware that as the wall begins to fade out, you are at the north end of the island and approaching the bay that is home to two marinas, with lots of boat traffic.  Be careful not to let yourself be swept around the corner into the Titlow area, as surfacing in all of that boat traffic could really ruin an otherwise beautiful day.
