Passage Index

Collection counts divided by the proportion of water passing through the sampling system.  These are not population estimates, but are used to adjust collection counts for daily fluctuations in the site's or project's operations and to determine run times.

IN SEASON - use in season

PassIndex = round(case when site in ('bo2', 'ris') then sum(collectioncount)*((avg((phouse1flow+phouse2flow+totalspill) /phouse2flow)))when site in ('jda', 'mcn', 'lmn', 'lgs', 'lgr') then
sum(collectioncount)*((avg((phouse1flow+ totalspill) /phouse1flow)))
else null end,0)

POST SEASON  - these queries use finalized flow data for all sites except Bonneville and Rock Island

PassIndex = round(case when site = 'bo1' and datepart(yy,a.sampleenddate) between '1986' and '1999' then sum(collectioncount)*((avg((phouse1flow+phouse2flow+totalspill) /phouse1flow))) 
when site = 'bo2' and datepart(yy,sampleenddate) between '2000' and '2001' then sum(collectioncount)*((avg((phouse1flow+phouse2flow+totalspill) /phouse2flow)))

SpeciesCode

Chinook=CH, Coho=CO, Sockeye=SO, Steelhead=ST

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.  http://www.fpc.org/documents/metadata/chinook_morphology.htm View picture of morphological differences.

For information on subyearling versus yearling determination for 1991 and previous years see http://www.fpc.org/documents/metadata/215-91.htm FPC Memo 215.91, dated 04/29/91.

Morphology has worked better than size in that 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 mid-Columbia and lower Columbia SMP monitoring sites: RIS, MCN,JDA, and BON. 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 conditionsof subyearling chinook growth. Because mid-Columbia summer races look more like fall races than spring races, the morphology criteria developed in the lower 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 mid- and lower 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 from Wells Hatchery and the Turtle Rock acclimation pondstend to be made after mid-June, thus keeping overlap with yearling chinook migrants low, as does the absence of any releases of hatchery fall chinook in the mid-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 Count: Sample count divided by the sample rate, not adjusted for flow.  These may be constrained due to sampling effort or river flow.

Sample Count: Actual number of fish sampled

Rearing Disposition

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.

How Frequently Data is Updated

Current Year

The data is 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.
