[env-trinity] Mainstem Trinity River spawn survey update for November 20, 2015

[Rupert, Derek]

Hello All,

The US Fish and Wildlife Service along with the Yurok Tribe, California
Department of Fish and Wildlife, US Forest Service, and Hoopa Valley Tribe
have another weekly update for our Trinity River mainstem spawn survey
posted on the Arcata Fish and Wildlife Fisheries webpage.

Trinity River spawn Survey update November 20, 2015.
<http://www.fws.gov/arcata/fisheries/projectUpdates/TRSpawningSurvey/2015/TrinityReddUpdate_2015_11_20.pdf>

This week our crews mapped 186 redds (1,979 total for the year) in the
Reaches from Lewiston Dam  to Pigeon Point, and Hawkins Bar to Weitchpec
(mouth of Trinity River). The graph below is clipped from our weekly report
(limited to the river upstream of Cedar Flat).


​
Make sure to check out the video of two male Chinook Salmon fighting over
the rights to a redd. You can really see how viciously these big boys can
battle. The link is in the report above.

Cheers,
Derek
