Our Fish Passage Technicians will,

  • Conduct advanced on-site evaluations statewide for the Washington Department of Fish and Wildlife’s (WDFW’s) Fish Passage and Diversion Screening Inventory, including inspection, analysis, and reporting of human-made, in-stream structures such as culverts, dams, fishways, lake outlet screens, and water diversions.
  • Independently plan, organize, and conduct physical habitat evaluations of freshwater streams, including measurement of stream features such as pool-riffle ratios, channel width, water depth, temperature, substrate ratios, and stream gradient and estimation of canopy and in-stream cover.
  • Consider species use potential throughout the stream, and spawning and rearing habitat quality is characterized to develop priority index values for barrier correction.
  • Process physical and biological stream data, using established data conversion and statistical procedures, in Excel spreadsheets and Access databases.
  • Use GIS software (ArcMap and ArcGIS Pro) for creating maps of fish passage features and habitat assessment sites.
  • Use ArcMap, ArcGIS Pro, and GIS web applications for calculations relating to the analysis of habitat data and Level B Hydraulic Analysis, including stream gradient, stream length, elevations, precipitation, and drainage basin area.
  • Collect on-site data following a strict protocol that will be used to determine compliance rates for permitted projects and the long-term effectiveness of stream simulation and no-slope designs.



  • Work Setting, including hazards:
    1. These are primarily field positions with approximately 80% of the work week spent outside.  Incumbents will need to be able to work long hours in inclement weather conditions along busy state highways and walk streams through thick vegetation, climbing over and around log jams and wood debris on uneven terrain and slippery surfaces while carrying up to 30lbs of field gear.
    2. The other 20% of the work week is spent in the office entering data with typical office hazards (e.g. sharp edges on desks, unprotected corners on overhead cabinets, unsecured shelving and cabinets, and tripping hazards).
  • Schedule:
    1. Typically, 7:00AM – 5:30PM Monday – Thursday.
    2. May include evenings and weekends.

    2. Overnight travel required.
  • Tools and Equipment:
    1. Survey equipment (laser, auto level, stadia rod, gravel probe), machete for brushing, other pertinent sampling gear as needed for data collection per the protocols found in the Fish Passage Barrier and Surface Water Diversion Screening Assessment and Prioritization Manual.
  • Customer Interactions:
    1. Represent the Washington Department of Fish and Wildlife in a professional manner.
    2. Have professional and respectful dialog with other agencies, state and local government officials, Tribal members and representatives, local entities, civilians, etc.
    3. Contact landowners before entering private property.
