Annual Number of Emigrating Juvenile Chinook Salmon per Redd

Cedar River juvenile Chinook salmon express an “ocean type” early life history. The vast majority of young Cedar River Chinook emigrate downstream out of the Cedar River during their first year of life. Many emigrate as “fry” very shortly after they emerge from the gravel redds in which they have incubated all winter. However, a substantial portion of the population remains to rear in the river for up to 3-months, them moves downstream as “smolts”. The number of emigrating juveniles per redd is an indicator of overall river conditions for juvenile Chinook production in a given year.
