Internal database ID that identifies a population.

Internal database ID that identifies the detailed record.

Internal code used for displaying the ESU on a map.

Internal database ID that identifies the ESU.

Common name of the taxon of fish.

A group of fish of the same species that spawns in a particular locality at a particular season and does not interbreed substantially with fish from any other group.

Unique ID associated with the ESU/DPS, population name and run time.

Discrete geographic areas for which comprehensive recovery plans are being developed: Puget Sound, Willamette/Lower Columbia, Interior Columbia (including the Mid-Columbia, Upper Columbia, and Snake River sub-domains), Oregon Coast, and Southern/Oregon Northern California Coast.

Major Population Group, as defined by the NWR. Groups of populations within an ESU/DPS that are more similar to each other than they are to other populations. They are based on similarities in genetic characteristics, demographic patterns and habitat types and on geographic structure.

For populations listed under the federal ESA, this is the name of a defined Evolutionary Significant Unit (ESU) or Distinct Population Segment (DPS) as defined by NMFS Northwest Region or by USFWS.

Salmon species name.

Run of fish, generally determined on the basis of the time of year at which adults enter fresh water to spawn. (Spring, Summer, Spring/Summer, Fall, Winter, early, or late)

The first date the data was collected.

The latest date the data was collected.

The year that adults enter the river to spawn.

The fraction of the total spawners that are the progeny of naturally-spawning fish.

The fraction of fish who are defined as having an age of 1 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 2 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 3 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 4 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 5 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 6 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 7 that returned to spawn in a given year.

Obsolete column.

Estimated number of natural origin (parents spawned in the wild) spawners contributing to spawning in a particular year. Includes both adults and jacks of natural origin.

Estimated total number of fish contributing to spawning in a particular year. Includes both natural origin and hatchery origin returns, adults and jack age classes.

Estimated number of natural origin (parents spawned in the wild) spawners contributing to spawning in a particular year. Includes only adults of natural origin, excluding jacks.

If available, estimate of the relative proportion of hatchery returns to the spawning ground that are jacks (i.e., age 3 fish for stream type chinook populations, age 2 fish for ocean type chinook populations).

The estimated proportion of adult returns removed by harvest in a particular run year. Assumes that all adult age classes are harvested at the same rate. Steelhead and yearling type chinook estimates reflect in-river fisheries. Snake River Fall chinook estimates also include an adjustment to incorporate an index of annual ocean impacts.

Fish of natural origin removed from the returning run for use as hatchery broodstock.
