An update with our latest redd survey results is available from the link in
the bottom message.

Numbers will look deceivingly low with this week's report (162 new redds
marked).  Due to logistics around the Thanksgiving holiday, no survey was
conducted of Reach 1 (Lewiston Dam to Old Bridge), nor Reach 8 (Pigeon
Point to Big Bar).  Crews are getting Reach 1 covered today (11/29) and
those results will be available with next week's update.

Thanks for looking!
Charlie

Hi all,
Another update reflecting the redds recorded November 15 to 19 will soon be
posted at the link in the bottom message.  Over this period our crews
recorded 588 new mainstem Trinity River redds; 475 from Lewiston Dam to the
North Fork and 113 from Hawkins Bar to the mouth.

I hope you all have a great Thanksgiving!
Charlie

Another update of our preliminary redd counts is available through the link
below.  Reaches 2 and 8 (Old Bridge to Bucktail, and Pigeon Point to Big
Bar) were not surveyed due to the shortened workweek (Thursday was
Veteran's Day).  Reach 1 is taking off with 172 of the total 294 redds
counted last week.  Our season's total count is 2,483 as of Friday 11/12.

I've been told that some of the redds in the Google Earth file show up on
land.  Don't worry, there aren't mutant salmon spawning on dry ground!
Most of these "dry" redds are attributable to image alignment of the latest
aerial photos by Google.  Regardless, they line up darned close so still
give you a good sense of the distribution of redds.  It's been great to be
able to share that with you all with such resolution!

Talk to you next week,
Charlie

Hi all,
It's that season again!  Fall 2010 salmon spawning surveys of the mainstem
Trinity River are underway.  These are conducted collaboratively by the
Arcata Fish and Wildlife Office, California Department of Fish and Game,
Yurok Tribal Fisheries Program, Hoopa Valley Tribal Fisheries Department,
and the Shasta-Trinity National Forest.  Our first within-season update for
the 2010 redd survey is available from the Arcata Fish and Wildlife Office
Website at the link below.  Click on "Trinity River 2010 Redd Survey
Update" near the bottom of the page.  We will make updates available
throughout this season at this same site.

Here's to hoping for a great run this year.
Cheers!
Charlie
