Jill Hardiman

Hello welcome to my professional page.  I have been working in the field of fisheries biology for over 20 years.  Most of my career has been with the USGS either as an employee or contractor.  I have also worked as a fisheries observer for NMFS program many years ago as well as completed my Master's degree and research and teaching related responsibilities at Colorado State University.



M.S. 2003. Fishery Biology, Colorado State University, Fort Collins, CO

B.S. 1992. Biology, University of Puget Sound, Tacoma, WA


Research Interests:

My interests lie in ecosystems change as it relates to large landscape scales stressors such as climate change, land use/development and invasive species.  My areas expertise include Geographic Information Systems (GIS), data management, project management, monitoring and habitat assessments, and salmonids.



3/2004 to Present - Fish Biologist, U.S. Geological Survey (USGS), Columbia River Research Laboratory (CRRL), Cook, WA

Major projects: Regional coordination of monitoring efforts for invasive mussels in the northwest states based on prior risk assessment models and sample design for local efforts; Predator/prey study of juvenile salmon consumption by native and non-native species; bioenergetics modeling of the effects of climate change on the growth of fish; development of a probabilistic based sample design framework for Columbia and Snake rivers status and trends monitoring;  invasive species surveys and habitat assessments in the Columbia River and tributaries. Past team leader of a telemetry (hydroacoustic and radio) project evaluating the effects of juvenile salmonid passage histories at hydroelectric dams in the Snake River on their survival to McNary Dam, Columbia River, as well as various juvenile salmon survival studies for the Lower Columbia River dams. Primary responsibilities:

  • Prepare professional presentations, reports, research proposals, and manuscripts
  • Project design, field and lab oversight, and project reporting and communication of results
  • Database management and analyses
  • Create Statistical Analysis Software (SAS) programs to manipulate and analyze large databases
  • Prepare Geographic Information Systems (GIS) databases, maps for study design, presentations, and analyses
  • Design and conduct invasive species surveys with global positioning system (GPS) and GIS focusing on habitat strata and a probabilistic sample framework
  • Develop and implement Quality Assurance Plans for research projects
  • Attend regional meetings, communicate research, and provide technical reviews

8/2003-3/2004 - Fishery Biologist IV, Johnson Controls Inc. contract for USGS/CRRL 

Research team member studying juvenile salmonid passage and survival at hydroelectric facilities on the Lower Columbia River using telemetry.  GIS development using hydrodynamic models to investigate community dynamics of native and non-native species above and throughout Bonneville Dam reservoir.  Primary responsibilities:

  • Prepare professional presentations, reports, research proposals, and manuscripts
  • Perform database management and analysis using SAS programs and other software tools
  • Prepare GIS database, maps for study design, presentations, spatial analysis, and reports
  • Supervise and train data processors and field technicians

8/2000-5/2003 - Graduate Research/Teaching Assistant, Colorado State University, Department of Fishery and Wildlife Biology

Principle investigator studying seasonal changes in horizontal and vertical distribution of age-0 kokanee at Blue Mesa Reservoir, CO with respect to changes in reservoir limnology and predator and zooplankton distributions. Assist teaching senior level fishery science and sophomore level wildlife conservation courses.  Primary responsibilities:

  • Professional presentations, student consultations, grading, reports, thesis, and professional manuscript
  • Design and implement mobile hydroacoustic surveys on a large reservoir at night
  • Conduct sampling of age-0 kokanee with gill nets, seines, and mid-water trawls in rivers and reservoirs
  • Conduct limnological surveys for zooplankton and water quality parameters
  • Perform bioenergetics, stomach capacity, feeding rate, and time to satiation modeling
  • Perform database management and analysis with SAS and other software on large data sets
  • Supervise two to three technicians in the field and laboratory

3/1996-7/2000 - Fishery Biologist, USGS/CRRL

Tagging crew leader evaluating juvenile salmonid passage and survival at three hydroelectric facilities on the Lower Columbia River using radio telemetry equipment on dams and in boats using a GPS. Responsible for collecting data on the movements, distributions, and behavior of juvenile salmonids. Primary responsibilities:

  • Design and implementation of radio tagging field stations, and supervision of 6 employees
  • Training of new employees in tag implantation techniques, GPS procedures, data management, mobile tracking, boat maintenance, handling and trailering procedures
  • Set up and maintenance of radio telemetry equipment
  • Receive, organize, and allocate for specific timed releases 5000 radio telemetry tags at four dam sites on the Lower Columbia and Snake rivers
  • Manage large data sets, prepare reports and presentations
  • GIS database development and management
