DART PIT Tag Adult Reach Distribution and Delay Overview

The DART PIT Tag Adult Reach Distribution and Delay analysis presents daily departure-date cohort calculations to help elucidate the more numerous visual count adult population movement patterns. Actual pre-season and in-season management decision processes are complex employing multiple sources of observed data, models, and forecasts.

Methods

On a daily basis, the DART database loads current PTAGIS, Smolt Index, River Conditions, and Adult Visual Counts datasets from primary sources.

Three populations based on release attributes are tracked separately for analysis.

Spring/Summer Chinook, juveniles released at/above Lower Granite, includes Unknown-run tagged at Lower Granite in April and May in same year as release. Tracked for spring spill period at Snake River dams, April 3 - June 20 and adult visual counts spring/summer run dates, April - August.
Spring/Summer Chinook, juveniles released at/above McNary. Tracked for spring spill period at mainstem Columbia River dams, April 10 - June 15.
Fall Chinook, juveniles released at/above Lower Granite, includes Unknown-run tagged at Lower Granite after June in same year as release and Unknown-run tagged by coord_id "WPC". Tracked adult visual count fall run dates, August - November.

For each unique Tag Id detected at the lower project as life stage adult, individual coil detections are examined to establish movement maps through the ladders and determine departure dates (may be more than one). Tag Ids are grouped by departure date into a daily cohort and each departure-date cohort is tracked separately for reach travel time, conversion rate, and arrival. Fallback, delay, wander, harvest, and/or mortality may result in <100% daily cohort conversion rate; fallback, wander, harvest and mortality are not included in these analyses. The PIT Tag population as a whole is tracked by unique Tag Id for YTD calculations of harmonic mean reach travel time and conversion rate.

On a date-specific basis, a unique population departing the lower project is established. Ascent events are not restricted to calendar date. This date-specific unique population is tracked to determine cumulative arrival percent at the upper project, harmonic mean TT, and conversion rate. A history of more than 1 ascent event for a TagID is tracked. This may impact arrival success and travel time.

Additional notes:

Adult Visual Counts presented are the daily sum of adult and jack counts.
Analysis for the year may be incomplete if viewing current calendar year results. YTD and Daily statistics may change and update as the year progresses.
Running 3 Day calculations requires a minimum 7 fish departing during each 3 day period.
Upper Project 50% Entry Hour requires a minimum 5 fish arriving on each date.

Criteria

Potential Delay alerts and shading of table cells are based on criteria set by population and reach. Potential Delay Alert: Cumulative Arrival Percent is less than criteria setting by "Average" calendar days after departure to Arrive.

Figures

Running 3 Day Travel Days and Run Size

Top: Daily analysis is smoothed by creating running 3-day calculations. The stacked Running 3 Day plot shows the cumulative arrival percent by days to arrive for each 3-day departure cohort.

Potential delay conditions are highlighted by filled gray dots; the criteria for potential delay is that the Cumulative Arrival Percent of the 3-day cohort is less than the arrival percent criterion value by the "Average" travel days. The average travel days and arrival percent criterion are based on historical observations for each reach and population.
The orange triangles represent the cumulative arrival percent by the "Average" travel day.
Cumulative arrival percent for one day prior (blue stars) and one day after (purple diamonds) the average are presented for boundaries around the average day; the boundary days can highlight movement trends for the cohort.
The gray pentagons represent the slow and final arrival percent which accumulates over the calendar year (conversion rate). Slow is defined as 5 or more days after "Average".

Middle: Percent of fish ‘In Route‘ for each running 3-day cohort; complementary/inverse plot to the arrival YTD% (conversion rate) presented in top plot. Percent ‘In Route‘ is reported immediately for the cohort. Note: Delay, fallback, wander, harvest, and mortality can all contribute to YTD Conversion Rate never reaching 100% and Percent 'In Route' never reaching 0%.

Bottom: Running 3-day PIT Tag departures plotted with running 3-day Adult Visual Counts for visual comparison of reach entry of the two data types.

Daily YTD Conversion Rate

Daily Year-to-Date (YTD) Conversion Rate for Adult PIT Tag and Adult Visual Count datasets. Visual comparison of trends between the two datasets. For each calendar day, the YTD Conversion Rate is calculated based on cumulative number of fish to date at the lower project and the cumulative number of fish to date at the upper project. There is no adjustment for travel time or harvest in these calculations.

Daily YTD Conversion Rate = cumulative total fish at upper to date / cumulative total fish at lower to date

example Daily Year-to-Date (YTD) Conversion Rate graph

Daily Reach Travel Time

Adult PIT Tag Daily Reach Travel Time with Harmonic Mean Reach Travel Time for cohorts grouped by lower project departure date.

Harmonic Mean Travel Time = number of unique fish detected at the detection site / ( (1/reach travel time) )

When dealing with travel times, we are primarily interested in the speed with which fish travel from point A to point B. The harmonic mean is a good statistic for describing a particular group's speed. 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).

YTD Harmonic Mean Travel Time and Historical Average Reach Travel Time are presented as well.

Daily Conversion Rate

Daily Conversion Rate for Adult PIT Tag population grouped and tracked by lower project departure date within the selected period.

Departure Date Conversion Rate = total number of arrivals for fish based on Tag ID that departed lower project on date / total number of departures (not unique Tag ID) on date

Arrivals for all departure dates are updated daily throughout the year as fish arrive at the upper project. There is no date restriction on when the fish must arrive for inclusion. YTD Conversion Rate is calculated for unique Tag IDs.

Note: Delay, fallback, wander, harvest, and mortality can all contribute to daily and YTD Conversion Rate never reaching 100%.

Cumulative Passage at the upper project for Adult PIT Tag and Adult Visual Counts

Cumulative Passage at the upper project for Adult PIT Tag and Adult Visual Counts is presented at the end of the season for movement comparison of the two datasets. Cumulative passage percent is calculated for both Adult PIT Tag (PIT) and Adult Visual Count (VC) populations at the upper project. To compare the cumulative passage of both datasets, MAD (mean absolute difference) is calculated for the middle 95% of the YTD Adult PIT Tag passage at the upper project. For each day in the middle 95% of the Adult PIT Tag run, mean absolute difference (MAD_j) is calculated and summed and the number of days is tallied.

MAD_season = (|(cumPassagePIT_j - cumPassageVC_j)| )/ number of days

example Cumulative Passage at the upper project for Adult PIT Tag and Adult Visual Counts graph

Daily Distribution of Entry Hour at upper project

Daily Entry Hour Distribution of Adult PIT Tag population and Spill Percent at the upper project, by calendar date. Arrivals at the upper project are tracked on a daily basis for entry hour. For each day's population, the distribution of entry hour is calculated for the hour when 25%, 50%, and 75% have entered. There is a required minimum of 5 entries/day set for calculations.

Hourly Spill Percent and Tailrace TDG Percent

Hourly Spill Percent and Tailrace TDG Percent for the upper project queried from the DART database.

Upper Project Entry Hour

Entry hour distribution for Adult PIT Tag at the upper project for the whole period.

Glossary

The following are presented in the daily table (Daily Fish & Water) with a subset presented in the Running 3 Day table and in plots. The majority of analysis presented is tracked by departure date.

Adult PIT Tag Data for Fish Departing [lower], grouped by Departure Date

Departure Events [lower]: Departure events
[upper] Entry Events for Fish departing [lower]: Number of arrivals
Unique TagIDs [lower]: Unique Tag IDs in cohort. A difference between unique TagIDs and Departure Events indicates that 1 or more fish had a repeat ascent for the same date.
Fish departing [lower] on date with history of >1 ascents: Number of Tag IDs departing with multiple ascents, either on that date or prior dates.
%Fish departing [lower] on date with history of >1 ascents: Percent of Tag IDs departing with multiple ascents. The number departing with history >1 ascents divided by the number of Departure Events.
Cumulative Arrival Percent [upper] Calendar Days after [lower] Departure: Arrivals at upper project by calendar days after departure, which can range from 0 (fast fish in a short reach, e.g., 5/15/2018 LMN->LGS) to over 100.
- Conversion Rate: number of arrivals / number of departure events.
  There is no date restriction on arrival date at the upper project; conversion rates (daily and YTD) are updated throughout the calendar year.
Note: Delay, fallback, wander, harvest, and/or mortality can all contribute to daily and YTD Conversion Rate never reaching 100% and percent 'in route' never reaching 0%
Harmonic Mean Reach TT (travel time)
- number of unique fish detected at the detection site / ( (1/reach travel time) )
When dealing with travel times, we are primarily interested in the speed with which fish travel from point A to point B. The harmonic mean is a good statistic for describing a particular group's speed. 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).
Percent Not Arrived for period: Percent 'in route' (plot and running 3 day table).
- (departure events - number of arrivals) / departure events

There are several additional parameters that are tracked and presented by calendar date.
