  1. Click on a column header to sort the table by that column.
  2. Number released with the adipose-fin clipped and a coded-wire tag (CWT).
  3. % Loss of Number Released = (Confirmed Loss/Number Released)*100.
  4. Chinook outside of the length-at-date criteria (Delta model) are not reported.
  5. The following CWT Tag Codes with confirmed recovery were used for more than 1 release group (release date, hatchery, production, race combination); the tag codes have been excluded from the table. In this dataset, there is no way to differentiate which release group was recovered if a CWT Tag Code is used for more than one. Please refer to the next table Multiple Release Groups for details.

Data Set Notes:

  1. We obtain salvage data from Fish Salvage Monitoring, CDFW Bay Delta Region
    • Salvage Database, ftp://ftp.dfg.ca.gov/salvage/
    • We use loss estimation methods as detailed in "Chinook Salmon Loss Estimation for Skinner Delta Fish Protective Facility and Tracy Fish Collection Facility, 2/15/2013" ftp://ftp.dfg.ca.gov/salvage/Salmon%20Loss%20Estimation/Salmon%20loss%20estimation%2002152013.pdf
    • 20 April 2018: Due to an update strategy based on unique row identifiers, the SacPAS database occasionally accumulated duplicate rows of salvage data at the SWP and CVP. This resulted in salvage and loss numbers inflated by approximately 20% during the season (February-April, 2018). We have improved our data assimilation process and now report salvage and loss in line with the numbers from CDFW-Bay Delta Region. We would like to thank Geir Aasen at CDFW for his assistance in identifying and resolving this issue with SacPAS salvage and loss calculations.
  2. We obtain export data from two sources:
    • Acrefeet in the Access database posted to ftp://ftp.dfg.ca.gov/salvage/ - the entire record is loaded daily
    • CFS from the CDEC sites HRO (for SWP) and TRP (for CVP) - 7 day window loaded daily
  3. The Delta Outflow, Sacramento River and San Joaquin River flow data are obtained from two sources:
    • CFS from CDEC for FPT (for Sacramento River), VNS (for San Joaquin River), DTO (for Delta Outflow) - 7 day window loaded daily
    • CFS for FPT+SRWTP, VNS, and NDOI from DWR operations control documents posted to http://www.water.ca.gov/swp/operationscontrol/deltaops.cfm - 30 day PDF window loaded daily
  4. The Cross Channel Status is obtained from the log and change order PDFs located at https://www.usbr.gov/mp/cvo/ - The Cross Channel condition is checked daily via the "Latest Cross Channel Gate Order", and updates are extracted from the PDF log which is published at https://www.usbr.gov/mp/cvo/
  5. On a daily basis, SacPAS calculates the OMR tidally filtered flow and the OMR index based on methods as described in:
    California Department of Water Resources (DWR). 2017. Old and Middle River Flow Review: USGS Gauge Readings versus Index Calculations for 2011 through 2017. Online: http://deltacouncil.ca.gov/docs/old-and-middle-river-flow-review-usgs-gauge-readings-versus-index-calculations-2011-through
    See OMR Tidally Filtered Flow and Index Calculations as performed by SacPAS for full details. SacPAS calculated OMR Index is available for 28 October 2016 to the present.
