[env-trinity] Mainstem Trinity River spawn survey update for October 30, 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 October 30, 2015.
<http://www.fws.gov/arcata/fisheries/projectUpdates/TRSpawningSurvey/2015/TrinityReddUpdate_2015_10_30.pdf>

This week our crews mapped 293 redds (1,506 total for the year) in the
Reaches from Lewiston Dam  to Pigeon Point, and Big Flat to Cedar Flat. The
graph below is clipped from our weekly report (limited to the river
upstream of Cedar Flat).

​
Coho Salmon have been seen moving through the Trinity. They will begin
spawning soon and the field crew will mark their redds. Let's hope that the
Coho show up in force and boost our total redd count for the year.

Cheers,
Derek
