Abstract
River discharge and water temperatures that occurred during April through July 2004 provided conditions suitable for spawning by white sturgeon downstream from Bonneville, The Dalles, John Day, and McNary dams. Optimal spawning temperatures in the four tailraces occurred for 3-4 weeks and coincided with the peak of the river hydrograph. However, the peak of the hydrograph was relatively low compared to past years, which is reflected in the relatively low monthly and annual indices of suitable spawning habitat. Bottom-trawl sampling in the Bonneville Reservoir revealed the presence of young-of-theyear (YOY) white sturgeon.
