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 4, 2015.

This week our crews mapped 119 redds (2,124 total for the year) in the
Reaches from Lewiston Dam  to Pigeon Point, and Hawkins Bar to Tish
Tang. The graph below is clipped from our weekly report (limited to the
river upstream of Cedar Flat).

There was no weekly report published last week (11/23 - 11/27) due to to
the Thanksgiving holiday. Only four reaches were surveyed. The data is
included in the report above.
