Fish and other sea creatures are finding some room to breathe in southern Hood Canal as higher oxygen levels have returned to the upper portion of the waterway after things looked pretty bleak on Monday. See Water Ways post.
I reported yesterday that fish could safely go down to 60 feet in a story posted on the Kitsap Sun website, but conditions are changing all the time. Now it looks like the cutoff depth is closer to 50 feet, while waters closer to the surface appear to be more oxygenated than yesterday.
I discussed the situation with Dan Hannifious of the Hood Canal Salmon Enhancement Group and included some of Dan’s comments in the story. Rather than repeat those comments here, I’ll let you click on the story.
What I did want to share are a couple graphs that show current conditions as of 9:30 this morning. Most of the real-time analysis comes from monitoring buoys in Hood Canal.
