1998 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 LGS, LMN and MCN. All mortalities are reported as happening at Lower Granite since there is no way to determine which project or sample the morts originated from.
