The short answer is 'sort of'.
When the Willamette goes, so goes most of the lower river. Add to that any color being tossed into the CR from the Sandy, Washougal, Lewis, Kalama and the Cowlitz, and it may be more brown than green. You may recall a few years ago when the Willamette was puking mud and the CR was relatively clear, Frenchmans Bar and the mud line around the mouth of the Willie were red hot as fished staged just outside the Willamette.
With a little luck, the rivers will clear relatively quickly and get us back to 'normal' spring time color.
