68656 SPS Data 1949 to 2010 Entity Published / External 68642 Salmonid and Steelhead Population Abundance Summary from 1949 to 2010 for Washington, Oregon, and Idaho Data Set Completed The data contained in the SPS database are primarily summary data, compiled at the population level. The database also includes a limited number of series representing the aggregate returns to groups of populations (e.g., Lower Granite Dam counts) or counts of spawners within a subsection of a population where expansions to the population level were not feasible. The information used to develop the population level estimates comes from a variety of sources, but mostly originates from the monitoring programs conducted by state and tribal fishery agencies. The Technical Recovery Teams and Northwest Fisheries Science Center staff have processed this information to provide an estimate of spawning abundance at the population level. A variety of different types of information (e.g., redd counts, dam counts, carcass surveys, tag recoveries, scale analysis) forms the basis of the information in the database, and where possible the database provides references to these information sources. It is important to recognize that spawning abundance values and other information in the SPS database are not 'facts' that are known with certainty. Rather, they are estimates based on a variety of sources of information, some known with greater precision or accuracy than others. Ideally, these estimates would be characterized by a known level of statistical uncertainty. However, for the most part such a statistical characterization is either not possible or has not been attempted, and the database reports only the best estimates of the values. In all cases there is some degree of uncertainty surrounding these estimates. The NWFSC intends to work with our state and tribal partners to keep the SPS database as up-to-date as possible, and new annual estimates will be added as they become available.

Please note that the value -99 is used to represent "null" data for several columns for several populations. This value was used for modeling purposes. A -99 value in the NMFS_POPID indicates that the population data was collected before population names were finalized. 1 NMFS_POPID NUMBER 22 No No Active The unique numeric value for a population as determined by NMFS. This value will not change over time, even if the population name (NWR Population Name) does. A -99 value in the NMFS_POPID indicates that the population data was collected before population names were finalized. 2 COMMON POPULATION NAME VARCHAR2 100 No No Active Name of population as people may commonly refer to it. 3 NWR POPULATION NAME VARCHAR2 255 No No Active Name of the population as defined by the West Coast Region of NMFS. 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. 4 RECOVERY DOMAIN VARCHAR2 50 No No Active After listing 27 Pacific salmon Evolutionarily Significant Units (ESUs) as threatened or endangered under the Endangered Species Act, NMFS initiated a coast wide process to develop recovery plans for these species. An important part of this process was the creation of geographically based Technical Recovery Teams (TRTs) and recovery areas (domains). 5 MAJOR POPULATION GROUP VARCHAR2 50 No No Active A group of salmon populations that are geographically and genetically cohesive. The MPG is a level of organization between demographically independent populations and the ESU or DPS. 6 ESU NAME VARCHAR2 100 No No Active A group of Pacific salmon or steelhead trout that is (1) substantially reproductively isolated from other conspecific units and (2) represents an important component of the evolutionary legacy of the species. 7 SPECIES VARCHAR2 40 No No Active The name of the specie that the population belongs to. 8 RUN VARCHAR2 50 No No Active The Season of the Year represented by this viability figure for the population. 9 START YEAR NUMBER 22 No No 0 Active The earliest year that viable salmonid population statistics are reported for this population. 19 END YEAR NUMBER 22 No No 0 Active The latest year that viable salmonid population statistics are reported for this population. 20 YEAR NUMBER 22 No No Active The year that adults enter to the river to spawn. 23 NUMBER OF SPAWNERS NUMBER 22 No No Active The total number of fish returning to spawn in the data collection year. 25 FRACTION WILD NUMBER 22 No No Active The fraction of the total spawners that are the progeny of naturally-spawning fish. 29 AGE 1 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 1 that returned to spawn in a given year. 30 AGE 2 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 2 that returned to spawn in a given year. 31 AGE 3 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 3 that returned to spawn in a given year. 32 AGE 4 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 4 that returned to spawn in a given year. 33 AGE 5 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 5 that returned to spawn in a given year. 34 AGE 6 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 6 that returned to spawn in a given year. 35 AGE 7 RETURNS NUMBER 22 No No Active The fraction of fish who are defined as having an age of 7 that returned to spawn in a given year. 40 NATURAL SPAWNERS WITH JACKS NUMBER 22 No No Active 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. 48 TOTAL SPAWNERS WITH JACKS NUMBER 22 No No Active 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. 49 NATURAL SPAWNERS EXCLUDING JACKS NUMBER 22 No No Active Estimated number of natural origin (parents spawned in the wild) spawners contributing to spawning in a particular year.
