From January to July of 2003, 42 entrapments and 25 stranding sites were examined on the Columbia River near Ives Island, downstream of Bonneville Dam. A total of 6,122 salmonids, consisting of three different species, were collected at these sites (Table 1). The fish sampled during this time were chinook salmon (69%), chum salmon (7%), and coho salmon (24%). The following analysis of the relationship between environmental factors and salmon placed at risk by river level fluctuations focuses on each of these three salmon species.
