G: 162 - Analyze Adult Steelhead Abundance & Life History Data for Asotin and Tucannon Tributaries to Estimate Escapement

The principle task under this work element is to put together available trap and redd survey data (from work elements listed above) to construct adult escapement, distribution of natural origin summer steelhead and the proportion of hatchery steelhead into these tributaries associated with the Tucannon and Asotin populations. These estimates will be compiled and incorporated with similar estimates for core Asotin or Tucannon steelhead populations to provide more complete estimates of adult abundance and escapement composition (proportion of hatchery and naturally produced fish, source of hatchery fish) over a period of years.

WDFW will also compile tissue samples and associated fish data collected at the trap site. Local staff will then coordinate with geneticists in WDFW, CRITFC and IDFG and share samples for DNA and SNPs analyses.

In addition WDFW will monitor stream discharge by taking manual stream flows while operating traps to evaluate steelhead run timing.

WDFW may also monitor temperatures at each weir site while we are operating traps to compare with run timing of adult steelhead. Temperature monitors will be assessed both before and after the season against a calibrated thermometer to check accuracy of the data loggers.

These are short-term data sets incidental to trapping activities and project purposes; monitoring information is site-specific data, intended to be used for review by WDFW for the limited purpose of evaluating trapping operations, relative to run-timing, and informing management choices, including near-tern adjustments to implementation actions and future strategies.
Continue to assess flow and temperature trends associated with trap locations; evaluate relative to steelhead run timing. Compile and summarize flow monitoring data during adult steelhead spawning returns; record, compile and summarize water temperatures at trap locations.

The deliverable for this work element is always an error-checked dataset of the raw data uploaded to a publicly accessible site (such as StreamNet). The dataset has a distinct set of variables (data fields), and may be captured in a flat or relational database. Describe your dataset here.
Notes:
1. In your annual report (WE 132), you are required to provide a link to your data set with a file name in the report's first appendix. If not web accessible, provide instructions (e.g., file name, directory, or position title) for accessing data.
2. Any derived data will be produced under work element 162, Analyze Data.

This includes the following methods/metrics: adult escapement estimates based on trapping and/or redd count surveys for adult steelhead in small streams associated with the Tucannon and Asotin populations. Data will be publicly accessible, with stipulations for limitations of use and data generator attribution. Additional implementation notes and analysis will be in the Annual Report, or attached to the protocol as implementation notes.
The data file(s) will be stored on WDFW servers and provided to interested parties and co-managers upon request.
