v of river elevations in the Ives Island area confirmed earlier time-series temperature monitoring results and showed higher bed temperatures within chum salmon spawning areas than in fall Chinook salmon spawning areas. Riverbed temperatures in chum salmon spawning locations were influenced by fluctuations in river stage, decreasing during periods of elevated river stage. In fall Chinook salmon spawning locations, bed temperatures resembled river temperatures.
