1999 Barge and Truck Mortalities

The four transportation sites, Lower Granite, Little Goose, Lower Monumental and McNary collect barge and truck mortality data from the US Army Corps of Engineers. Barging begins at Lower Granite, with stops at Little Goose and Lower Monumental dams.  All mortalities are reported as happening at Lower Granite since there is no way to determine at which project or sample the morts originated.  Later in the season when McNary is the only operating collector project, mortalities will be attributed to McNary Dam.

NOTES:

  • *The Corp of Engineers has reduced the number of transportation mortalities for this week, instead calling them "special events fish."  Our numbers do not reflect this new category, rather represent the originally reported barging mortalities for that week.
  • Mortalities reported are for dead fish removed from the barge or truck. Only those mortalities found floating at the top of the holding tanks are removed.
  • Barge mortalities for chinook sub yearlings are reported as having an unknown rearing disposition because of the following:
    • Approximately 600,000 unclipped, mostly unmarked hatchery sub-yearling chinook were released above Lower Granite Dam.
    • Wild sub yearling chinook were clipped and CWT in the Hanford Reach.
