[env-trinity] Message from Arnold Whitridge transmitting messagefrom Doug Schleusner

[George Kautsky]

Arnold and others, I wish to inform preliminarily as to our observations at
Junction City Juvenile screw-trapping site.  My field biologist noted today
that captures are much lower than typically observed for this week in prior
years.  That is, the flood of hatchery steelhead and coho have not arrived
yet at JC as anticipated.  He further states that he has heard accounts of
large pods of juveniles holed up in vicinity of the old Lewiston Bridge.  We
should have preliminary tabulations for J.C. screw trap completed by early
next week and will distribute them to coop agencies.

Regards,
George Kautsky

  TAMWG and TMC,

  My e-mail capabilities currently exceed those of some entire Interior
  Department agencies, so I've been asked to circulate a message from the
  TRRP office.  As background, there was concern that the recent rampdown of
  Lewiston releases from 2000 cfs to 300 cfs would strand some juvenile
  fish.  To minimize stranding, Central Valley Operations modified the
  rampdown schedule as suggested by scientists who were meeting to discuss
  the annual flow schedule, but there were nevertheless some reports of
  stranding, including stranding of young coho.  Doug Schleusner reports
  (March 19):

  "Branch Chief Daryl Petersen and two other biologists (Mike Kelly, NOAA
  Fisheries; Loren Everest, Forest Service) floated the Trinity from the
  hatchery to Bucktail, and stopped at 5 sites where stranding had been
  reported or historically has occurred. Stranded salmon were observed at
all
  sites, but most were chinook, with some coho (native) observed at one
  location. It appears that at these sites there is still enough surface
flow
  to allow some fry to move back into the main channel, or the pools are
  large enough to allow fry to rear and survive until the spring flow
  releases begin to ramp up in late April or early May.  Mike Kelly will
  document their observations in more detail and contact other observers
down
  river; a report is expected by next Monday or Tuesday. At this point it
  does not appear necessary to mobilize a rescue effort or take actions
other
  than continuing to monitor the situation."
