aDuration of spawning and peak spawning timing reported for the Washington Department of Fish and Wildlife spawner survey database (WDFW 1994c) were estimated from the combined frequency of peaks in spawning activity in all survey areas within a given river basin, all years combined. Duration of spawning was estimated as the temporal range of these spawning peaks, while peak spawning timing was estimated as the time when the most spawning peaks occurred.
bDuration of spawning and peak spawning timing reported for Oregon Department of Fish and Wildlife (ODFW) spawner surveys were estimated from the combined frequency of peaks in spawning activity in all survey areas within a given river basin, all years combined. Duration of spawning was estimated as the temporal range of these spawning peaks, while peak spawning timing was estimated as the time when the most spawning peaks occurred.
c ODFW spawning survey data for 1984 was not available for any of the rivers surveyed by ODFW.
dODFW coastal spawning survey data was compiled from annual coastal spawning suveys (McGie 1983,1984, Jacobs1988a,1989; Cooney and Jacobs 1990,1992,1993, 1994).
