[env-trinity] Mainstem Trinity River spawn survey update for December 11, 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 December 11, 2015.
<http://www.fws.gov/arcata/fisheries/projectUpdates/TRSpawningSurvey/2015/TrinityReddUpdate_2015_12_11.pdf>

This week our crews mapped 12 redds (2,136 total for the year) in the
Reaches from Lewiston Dam  to Pigeon Point. The graph below is clipped from
our weekly report (limited to the river upstream of Cedar Flat).



Heavy rain has hit Trinity County and lead to high water turbidity below
the North Fork. We were unable to complete surveys below Pigeon Point.

Next week will be our last surveys of the year.

Cheers,
Derek
