    For Chinook, age code (CH0 or CH1) is a mixture of size, time of season, and morphology and is used to distinguish subyearling Chinook from yearling Chinook at each SMP monitoring site. Morphology differences have been successfully used in the Snake River drainage since 1992 to separate yearling Chinook (mixture of spring and summer races) from subyearling Chinook (fall race) at SMP monitoring sites: WTB, LEW, IMN, GRN, LGR, LGS, and LMN.

    RiverflowRiverflow is the average hourly river flow during the sample period.
    • Current Year: river flow is entered directly by SMP sites (may be uncorrected).
    • Historic Years: corrected data from the Corp of Engineers are used to estimate river flow.
    • Trap Sites: trap sites do not always enter riverflow. If the trap sites did not enter riverflow data, the riverflow line is set to zero on the graph.
    PartialSample
    • Partialsample = yes when sampled = y and sample hours is less than 24. The field includes: Y - #hours. This allows the user to not only see that it was a partial sample but also how many hours were sampled.

    • Partialsample = no when sample hours = 24
    Sampled
    • Y - sampling occurred on that date.
    • N - no sampling occurred on that date.
    SamplecountActual number of fish sampled.
    BatchBatch number consists of:
    • First three characters are the site abbreviation code.
    • Two characters for the year: YY.
    • Last three characters for the day of the year.
    PassIndexCollection divided by the proportion of water passing through the sampling system. These are not population estimates, but are used to adjust collection for daily fluctuations in the site's or project's operations and to determine run timing. The passage index is only estimated for salmonids and is not estimated at the SMP Traps.

    At Bonneville and Rock Island, flow and spill variables are based on data entered directly by SMP personnel and may be uncorrected.

    At all other bypass facilities, in the current year, flow and spill variables are based on data entered directly by SMP personnel and may be uncorrected. For historic years, flow and spill variables are based on data corrected by the Corps of Engineers.

    Data TypeDescription
    AgeCode

    A mixture of size, time of season, and morphology is used to distinguish sub-yearling chinook from yearling chinook at each SMP monitoring site. Morphology differences have been successfully used in the Snake River drainage since 1992 to separate yearling chinook (mixture of spring and summer races) from subyearling chinook (fall race) at SMP monitoring sites: WTB, LEW, IMN, GRN, LGR, LGS, and LMN. View picture of morphological differences.

    For information on subyearling versus yearling determination for 1991 and previous years see FPC Memo 215.91, dated 04/29/91.

    Morphology has worked better than size in the Snake River drainage because late migrating spring/summer Chinook yearlings from tributaries high in the drainage tend to pass Lower Granite Dam in June and July at lengths often smaller than the rapidly growing fall chinook subyearlings present then. Size differences, and morphology to a lesser degree, are the primary methods of separating yearling Chinook and subyearling Chinook at the Upper Columbia (RIS) and Mid-Columbia (MCN, JDA, BON) SMP monitoring sites. From fry size to smolts under 100 mm, there is little difficulty in separating subyearling Chinook from yearling Chinook. Above 100 mm, each site has to follow its own moving size threshold based on current conditions of subyearling Chinook growth. Because Upper Columbia summer races look more like fall races than spring races, the morphology criteria developed in the Mid-Columbia and now used in the Snake River can also help. But, as the season progresses, it is inevitable that only the larger yearling Chinook will be distinguishable from moderately large subyearling Chinook. Since few yearling Chinook are present in the Upper and Mid-Columbia River in late summer and early fall relative to the numbers of subyearling Chinook present, any impact of an occasional misclassification of a smaller yearling Chinook as a subyearling Chinook should be negligible. Fortunately, the hatchery subyearling summer Chinook releases in the Upper Columbia tend to be made after mid-June, thus keeping overlap with yearling Chinook migrants low, as does the low number of hatchery releases of fall Chinook in the Upper Columbia drainage above Priest Rapids Dam. It should be noted that recent shifts to earlier release dates (from May to April) for yearling hatchery summer Chinook to coincide more with release dates of yearling hatchery spring Chinook has not changed the tendency for yearling summer Chinook to migrate later than yearling spring Chinook.

    Counts
    • Collection: Collection is an estimate of the number of fish entering the juvenile bypass system. Collection is estimated as the sample count divided by the sample rate, not adjusted for flow.
    • Sample Count: Actual number of fish sampled.
    Descaling
    • NumExamDesc: The total number of fish examined for descaling.
    • NumDesc: The total number of fish descaled. A descaled fish in the smolt monitoring program is defined as a fish which is visually at least 20% descaled on either side.
    Mortalities
    • Sample Mortalities: Those mortalities that are found in the sample tank which have occurred since the last time the sample tank was examined, or mortalities directly caused by SMP staff.
    • Facility Mortalities: Non-sample mortalities observed at the project which occurred in the system and in transportation raceways.
    • Transportation Mortalities: Mortalities reported are for dead fish found floating at the top of the holding tanks from the barge or truck. The four transportation sites, Lower Granite, Little Goose, Lower Monumental and McNary collect barge and truck mortality data from the US Army Corps of Engineers. Barging begins at Lower Granite, with stops at Little Goose and Lower Monumental dams. All mortalities are reported as happening at Lower Granite since there is no way to determine at which project or sample the mortalities originated. Later in the season when McNary is the only operating collector project, mortalities will be attributed to McNary Dam. If you need transportation mortalities for other species, you can request the data from FPC staff at webmaster@fpc.org.
    • Research Mortalities: Those mortalities specifically caused by other non-SMP research conducted at the sampling facilities.
    • Tagging Mortalities: SMP PIT tag mortalities are those caused by SMP staff during SMP PIT tagging procedures.
    River Data
    • Riverflow is the average river flow during the sample period.
      • Current Year: river flow is entered directly by SMP sites (may be uncorrected).
      • Historic Years: corrected data from the Corp of Engineers are used to estimate river flow.
    Monitoring Hours The bypass facility sites normally operate from 7:00 am to 7:00 am. Traps typically start between 7:00 am and 8:00 am. Normal operation is for all sites to conduct 24-hour samples.

  • Rearing Disposition Notes for the Year 2000:
    • From hatchery information received by FPC for the year 2000 juvenile migration, it is our understanding that approximately 2.3 million unmarked, unclipped subyearling chinook smolts will be released into the mid Columbia and the Snake River zones of the Columbia Basin. Approximately 600,000 unmarked, unclipped steelhead will be released into the Upper Snake River. Approximately 540,000 unclipped yearling spring and summer chinook with coded wire tags will also be released in the Snake River Zone. All yearling chinook released in the Snake River Zone will have either a fin clip (adipose, ventral), or a coded wire tag. All Steelhead released in the mid-Columbia Zone will have either a fin clip or a coded wire tag.
    • The year 2000 juvenile migration presents a great difficulty for SMP personnel trying to identify the production origin of juvenile salmon and steelhead. Rather than rely on the subjective judgment of SMP staff to determine whether unclipped, unmarked fish are actually hatchery fish based on dorsal fin erosion, SMP personnel will objectively determine whether or not a fish is fin clipped, and check for coded wire tags in the case of certain unclipped fish species. They will not subjectively determine the rearing disposition. All unclipped yearling chinook will be examined for coded wire tags in the Snake River Zone, and all unclipped Steelhead will be examined for coded wire tags in the mid Columbia Zone.
    • Since Coho were determined in the past to be extinct in the Snake and mid Columbia Rivers, most present day observations of Coho in the basin are thought to be derived from hatchery stock, whether or not they are clipped or unclipped.
    • Sockeye are observed clipped and unclipped across the Columbia Basin. In the specific case of juvenile sockeye observed during the year 2000 migration, clipped fish are almost always of hatchery origin, and unclipped fish are almost always of wild origin.

    Smolt Monitoring Program Notes

    • The data are submitted each day. The site is responsible for proofing their data and resubmitting batches if errors are found. In addition, the Fish Passage Center reviews two batches per week and if errors are found, proofs two more batches. If errors are found in the batches, the site is notified to check that batch and make corrections if needed.
    • Historic data in the Riverflow field are from the Corp of Engineers.
    • The (LMN) data in 1985 were derived from hydro-acoustic monitoring and, as such, was considered first year baseline data, not appropriate or adequate for management decisions.
    • Prior to 2011, lamprey were considered an incidental species. Hence, several fields are not applicable in the historical data and are marked as NA or not applicable to lamprey.
    • The codes for incidental lamprey juveniles through 2010 included: LJ - Juvenile Lamprey; LB - Juvenile Lamprey Brown; and LS - Juvenile Lamprey Silver
    • Juvenile lamprey can escape the sample tank at LGR which could lead to unreliable estimates of collection. Therefore, we do not report lamprey collection estimates for this site.
    • Transportation at MCN stopped in 2013.
    • Over the years, several sites (e.g., MCN, JDA, LGS, LMN, and BON) have periods when samples are conducted every-other-day or even every second or third day. Please note the Sampled field to determine whether zero fish sampled is the result of no sample being conducted (Sampled = N) or a sample being conducted but no fish collected (Sampled = Y).
    • At times, the desired 24-hour sample may not be met, either due to equipment failure, high temperature sampling protocols, etc. Please note the PartialSample field to determine whether a sample was considered complete (PartialSample = N) or partial (PartialSample = Y). Also note the Comment field, as this may explain why a complete sample was not possible.
