[env-trinity] Mainstem Trinity River Spawn Survey Update for October 28, 2016

[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.
The full update is posted on the Arcata Fish and Wildlife Fisheries
webpage.

Trinity River spawn Survey update October 28, 2016.
<https://www.fws.gov/arcata/fisheries/projectUpdates/TRSpawningSurvey/2016/TrinityReddUpdate_2016_10_28.pdf>

This week our crews mapped 52 redds (1,380 total for the year) in the
Reaches from Lewiston Dam  to Cedar Flat. The graph below is clipped from
our weekly report (limited to the river upstream of Cedar Flat).


​​This weeks surveys were hampered by high flows and turbid water.  With a
period of drier weather in the forecast, we hope that surveys downstream of
Big Flat will be possible next week.
​
Cheers,
Derek
