* Trap locations may change.
Brood Year: This field contains the last two digits of the calendar year when eggs were deposited or collected, if known.
Forklength (Lgth): The length from snout tip to the tail fork, recorded to the nearest millimeter.
Hatchery: When fish are tagged at a hatchery, this field contains the four-character abbreviation from the domain of hatchery codes.
Migration Year: A field in a Tagging File used to record the last two digits of the earliest calendar year when fish are expected to smolt and out-migrate to the ocean. In the case of adults and/or recaptured fish, this value will generally reference the current year.
Observation Date (Obs_DateTime): The date and time the fish are detected at the observation site.
Observation Site (Obs): The three character site code where the fish are observed.
PIT (Passive Integrated Transponder) Tag: A computer chip attached to a wire antenna and encapsulated in a biologically inert glass capsule. The tag is excited when it is passed through the electromagnetic field of a detector and the information on the computer chip is transmitted to the detector. See Research: PIT-Tagging and Other Research Tools, Pacific Salmon Coordination Office for a short description and illustration.
Release Date (RelDate): The date the fish was released to a stream to rear or out-migrate naturally.
Release River KM: The release location expressed in river kilometers from the mouth of the Columbia River. This is a hierarchical coding scheme from the mouth of the Columbia River to the release site (up to 7th order streams for point release sites) with each tributary delimited with a period. For example, the Release River KM for Lower Granite Dam of 522.173 reflects a distance of 522 km from the mouth of the Columbia River to the mouth of the Snake River, and 173 km from the mouth of the Snake River to Lower Granite Dam.
Release Site (RelSite): The six character site code where the fish are released.
Intra-Dam Release Site Codes: These codes are appended as a suffix to the three-character dam site code and provide a specific location for release at, above, or below hydroelectric facilities. For example, a release into the gatewells at Lower Granite Dam would be coded as LGRGWL. Use of Intra-Dam Release Site Codes will be required after 12/31/99.

Tag Count: The total number of fish tagged during that particular release; it can range from single digits to thousands of fish.
Tag ID (Tag_ID): A unique 10- or 14-character hexadecimal code recorded on the computer chip in the PIT tag.
Tag Site: This field contains a code (between three and six characters) denoting the site where the fish were marked (see Tag and Release Site Codes). During a recapture event, this code designates the recapture site.
Tagging File (Tag_File): A file containing information from a PIT tagging session during which PIT tags are implanted in fish. A data file containing information pertaining to the original marking, release, recapture, or mortality of PIT-tagged fish.
Tagging Temperature: The temperature (ºC) of the tagging bath during the marking operation.
Travel (Days): The difference between the release date and the observation date. Note, this may include time spent in rearing and is therefore not a good estimate of actual migration time.
USGS Hydrologic Unit: An eight-digit code representing the primary through quaternary classifications of geographic mapping in the United States. The US Geological Service assigns code designations to watersheds; this eight-digit code defines the location of the release site. This information can be useful in GIS (Geographical Information Systems) applications. See USGS Hydrologic Units Maps for more information.
Weight: A field in a Tagging File used to report the weight of the fish, recorded in tenths of grams.
Survival Estimates: The survival estimates are calculated for a population of PIT-tagged fish as defined by the query.
The Survival Estimates tool uses Cormack-Jolly-Seber (CJS) estimates. The query results provide estimates and standard errors for the survival and detection probabilities, and the product of the final survival and detection probabilities. The standard error of all estimates are reported in parentheses. The estimate of the overall survival probability, i.e., the product of all the survival estimates, is reported as well.
For the CJS estimates to be valid, the following assumptions must be met:
- Individuals marked for the study are a representative sample from the population of interest.
- Survival and capture probabilities are not affected by tagging or detection. That is, tagged fish have the same probabilities as untagged fish.
- All detections are "instantaneous." That is, detection takes a negligible amount of time or distance relative to the length of the reaches between detection events.
- The fate of each tagged individual is independent of the fate of all others.
- All tagged individuals alive at the beginning of a reach have the same probability of surviving until the end of that reach.
- All tagged individuals alive at the beginning of a detection site have the same probability of being detected at that site.
- Each individual detected at a particular detection site has the same probability of being removed, and the probability of removal is independent of the survival process.
There are several limitations to the Survival Estimates produced by this tool.
- Depending on the selection criteria, the survival estimates will tend to over-pool releases.
- If you do not define the PIT Tag group specifically by a release site, then different release sites (and travel distances) will be included in the group; hence the assumption that all individuals have the same probability of survival may be violated for the first reach (release point to the first dam). Survival estimates for the other reaches (dam to dam) will be fine.
- If the PIT Tag group includes fish released from the same location but at different times, then the estimates will be a weighted average over time as a function of release size. If the probability of survival varies over time, the assumption that all individuals have the same probability of survival may be violated.
- The Survival Estimates tool is unable to produce estimates for the last dam because detection efficiency cannot be distinguished from survival for the final reach.
- Survival estimates are generated from capture histories for each fish that are based on data downloaded from the PTAGIS database system. The particular data used for these estimates contain only last detections and therefore do not take into account the full detection history for a fish at a given site and may not account for errors in detection sequence recording. This may lead to minor over censoring of the data that in turn may lead to slightly higher standard errors in parameter estimates when compared to systems that use the full detections history of the fish.
Mean Travel Time Estimates: The mean travel times are calculated for a population of PIT-tagged fish as defined by the query.
The travel time estimates are based on the release date for each pit-tagged fish as recorded in the PTAGIS database (and uploaded to the Columbia River DART database) and the first and last detection times at each downstream detection site. Travel Time estimates for release to downstream detection site are calculated using the release time and the time of the first detection at the downstream detection site. Between detection sites travel time estimates are calculated using the time of the last detection at the upstream site and the time of the first detection at the downstream site.
Arithmetic Mean Travel Time(reach travel time ) / number of unique fish detected at the detection sites
Harmonic Mean Travel Timenumber of unique fish detected at the detection sites / (When dealing with travel times, we are primarily interested in the speed with which fish travel from point A to point B. A good statistic for describing a particular group's speed is the harmonic mean. A harmonic mean is used when working with rates of speed, usually the number of days to travel a set distance. A benefit to using the harmonic mean is that it is more robust in the presence of outliers (i.e., a very fast or slow fish).

Note on Migration Year 2000:
There was an release of unmarked subyearling chinook upstream of Snake River Trap which occurred in May 2000. As the result, there was some problem in proper identification of juvenile chinook at the trap (SNKTRP) beginning with May 22, 2000. Some subyearling fall chinook were tagged as 15Ws (Chinook, Unknown, Wild) and included in the wild yearling spring/summer chinook ESU totals via detections from the SNKTRP. Detections at SNKTRP after May 22, 2000 of wild yearling spring/summer chinook have been excluded from the "Chinook, Wild Spring/Summer Yearling" category.
Barometric Pressure: Barometric Pressure is atmospheric pressure at the site, given in mm Hg. It represents an average of hourly measures. Barometric Pressure is measured at Water Quality Monitoring stations in the forebay and tailrace of most projects (see Data Sites Map) and other key locations in the basin. Prior to 1995, the data are from a variety of sources within the U.S. Army Corps of Engineers.
Dissolved Gas: Dissolved gas is a measure of the pressure of dissolved gas in the water column. When spillway water plunges into the tailrace nitrogen is forced into the water at higher than normal levels. This condition, called supersaturation, occurs when dissolved gas pressure in the water actually exceeds the atmospheric pressure. The dissolved gas value represents a daily average of hourly meeasures within the range of 600-900 mmHg and is derived from U.S. Army Corps of Engineers gas monitoring efforts. Often collected at irregular intervals, this parameter may be missing values for one or more days, or reported values may be obviously incorrect. Dissolved Gas is measured at Water Quality Monitoring stations in the forebay and tailrace of most projects (see Data Sites Map) and other key locations in the basin. Prior to 1995, the data are from a variety of sources within the U.S. Army Corps of Engineers.
Dissolved Gas Percent: Gas percent reflects the degree of total dissolved gas supersaturation in the river at the given location. Gas percent is the daily mean of hourly observations. When gas pressure is exactly the same as the atmospheric pressure, the water is considered to be 100% saturated. If the gas pressure value is higher than atmospheric pressure, gas percent values rise above 100%. Daily averages are calculated from hourly values within the range of 90% to 200%. Gas percent data is often found to be quite noisy due to rapid fluctuations in spill volumes and atmospheric pressures. Dissolved Gas Percent is measured at Water Quality Monitoring stations in the forebay and tailrace of most projects (see Data Sites Map) and other key locations in the basin. Prior to 1995, the data are from a variety of sources within the U.S. Army Corps of Engineers.
Elevation: Elevation is given in feet above mean sea level and is a daily average of hourly measures. At most sites this will change less than a fraction of a foot over normal operations. Elevation is measured in the forebay of a project.
Elevation 10 Year Average: Daily average of elevation for a selected 10 year range. For each month and day, the data is summed for the selected 10 years and divided by the number of non-null data points available during that 10 year span.
Inflow: Inflow measurements represent the 24-hour average of hourly measures, reported by the U.S. Army Corps of Engineers. Inflow is given in kcfs, thousands of cubic feet per second.
Outflow: Outflow measurements represent the 24-hour average of hourly measures, reported by the U.S. Army Corps of Engineers. Outflow is given in kcfs, thousands of cubic feet per second. This represents the total outflow at any project, including spill and fish ladder flow.
Outflow 10 Year Average: Daily average of outflow for a selected 10 year range. For each month and day, the data is summed for the selected 10 years and divided by the number of non-null data points available during that 10 year span.
Spill: Spill also is given as a daily average of 24 hourly measures taken by the U.S. Army Corps of Engineers. It is also given in kcfs.
Spill 10 Year Average: Daily average of spill for a selected 10 year range. For each month and day, the data is summed for the selected 10 years and divided by the number of non-null data points available during that 10 year span.
Spill Percent: Spill Percent is calculated by DART from the daily averaged value for Spill divided by the daily averaged value for Outflow at a project.
Temperature (Scroll Case): Temperature (Scroll Case) is water temperature in degrees Celsius. This data is measured at the scroll case (part of the powerhouse) at a project. If provided values are in Fahrenheit, they are converted to Celsius. Temperature records are typically not collected outside the salmon migration season, so they are not usually 365 days long. Values above 0 C and below 35 C are averaged for a daily value.
Temperature (Scroll Case) 10 Year Average: Daily average of scroll case temperature for a selected 10 year range. For each month and day, the data is summed for the selected 10 years and divided by the number of non-null data points available during that 10 year span.
Temperature (WQM): Temperature (WQM) is water temperature in degrees Celsius. This data is measured at Water Quality Monitoring stations in the forebay and tailrace of most projects (see Data Sites Map) and other key locations in the basin. Temperature records are typically not collected outside the salmon migration season, so they are not usually 365 days long. Daily averages are calculated from hourly values above 0 C and below 35 C. Temperature at water quality monitoring stations was not collected prior to 1995.
Temperature (WQM) 10 Year Average: Daily average of water quality monitor temperature for a selected 10 year range. For each month and day, the data is summed for the selected 10 years and divided by the number of non-null data points available during that 10 year span.
Turbidity: Turbidity measures the water clarity, and by inference, the amount of particulate matter present. Turbidity is measured in the forebay or in the fish ladders of a project. Turbidity is reported in feet and measured with a Secchi Disk. In general, the Secchi disk is a 20 cm circular black and white plate. The Secchi disk is attached to a calibrated line and lowered into the water to the depth at which it disappears. The disk is then lifted until it reappears. The arithmetic mean of the two depths is considered the Secchi disk transparency or limit of visibility.
The 10 Year Averages are calculated by DART for each calendar day of data at each project. For the current year and any given project/month/day, the data from the previous 10 years on that calendar day is summed and divided by the number of non-null data points available. Calendar day averaging was chosen because, historically, data observations begin on a specific calendar day. Calendar day averaging gives different results than day of year averaging.
