Over the past several years, low-oxygen events in Puget Sound's Hood Canal have caused significant die offs of marine life, including multiple species of fish, shellfish and invertebrates. While low-oxygen levels are not new, these low-dissolved oxygen events have become more frequent and longer lasting in recent years.
Hood Canal is an underwater fjord where normal oxygen exchange in the water takes place slowly because of the depth of the water and the canal's shape. Nitrogen entering the water from human sources stimulates algae blooms in the canal. When algae decomposes, it absorbs oxygen from the water. Under certain weather and wind conditions, the level of life-sustaining dissolved oxygen in the water drops so low that fish and other underwater species suffocate.
Parts of Hood Canal are prime habitat for slow-reproducing species, such as rockfish and lingcod. These fish are most susceptible to low-oxygen events because they normally live as long as 25 years before reproducing offspring.
The Washington Department of Fish and Wildlife (WDFW) filmed underwater conditions in Hood Canal during a Sept. 19, 2006, low-oxygen event. This underwater video was filmed near Sund Rocks on the west side of Hood Canal by WDFW Research Scientist Wayne Palsson.
WDFW is monitoring conditions in Hood Canal and is working to improve and restore Puget Sound's habitat as a sponsor of the Puget Sound Nearshore Partnership and an active participant in Gov. Christine Gregoire's Puget Sound Initiative.

What exactly is the answer? Less traffic from commercial boats? That kills commerce. Less recreational boat traffic? Fine more people should learn to sail anyway. Tighter regs on industry and waste disposal going into the sound? Good luck getting past lobbyist and legislature. It's the same old crappy thing. There is seemingly no balance to be had. And the suits with the money always win over the guys in the flannel trying to do the good thing.
Hood Canal is dying. We hear a bit on the local news when things are at their worst. But too little is being done because it costs money to fix even though the cost only goes up as we wait. And waiting too long may also mean there is no turning back. So sad.
This is awful. I took my diving certification in 1993 in Hood Canal and there was lots of life in the water - sea cucumers, rock fish, ling cod and crabs everywhere. So sad to see what has become of the canal. The area is somewhat depressed already, so further degradation of the canal will have a severe impact on the people who live along the canal.
this is very disturbing,, What is the cause.. This needs to be advertised and put at the attention of more people I live in the Pugetsound area and am a boater, this is the first I heard of this,, Id like to get a copy of this for out yachtclub or have a fish and wildlife person make a presentation to our club,
