SECTION 5. Facility Operations
Debris was light at the primary dewatering structure (PDS) and fish/debris separator throughout the week
consisting mostly of aquatic macrophytes. The Smolt Monitoring Facility remains in low outfall. Few birds have
been observed around the outfall structures during most of the spring out-migration.
No kelts were removed from the separator bars. Only one steelhead fallback was recorded crossing the separator
bars this week.
No Gas Bubble Trauma (GBT) symptoms were observed from continuing examinations this week. Please
follow this link http://www.fpc.org/CurrentDaily/Gbtsum.txt) to the FPC web page for seasonal results. For
other interesting information please see our PSMFC SMP web page (see link at top of page one) which includes
links to past weekly reports, annual reports, and field guide pictures.
The shift to subyearling chinook continued this week, going from 55% last week to 83% of the sample this
week . Of those, 20% to 35% met the USGS (≥10 grams) and NOAA Fisheries ( ≥100mm) tagging criteria.
SECTION 6. Research
Approximately 335 and 262 subyearling chinook were held for USGS and NMFS research projects, respectively
this week.
