Smolt Rearing Dispositions

The Unknown rear type category is a mix of wild and hatchery fish, so when unknown is listed along with hatchery and/or wild this means that the number of hatchery or wild fish counted is only a portion of the total number of fish with that rearing disposition.

¹For 1987-1990, no distinction was made between yearling and subyearling chinook at Lower Granite (LGR) and Little Goose (LGS) dams. All chinook were reported as one species. Counts for those sites can be queried under yearling chinook (Chinook-1).
