How We Measure

Charting a Course to Recovery

Measuring the number of fish, the health of their habitats, and recovery plan implementation provides information to determine how well salmon are recovering.

At the scale of the recovery region, data is used to adaptively manage so that the recovery plans are implemented most effectively. At the state scale, data is used to inform harvest, hatchery, and habitat management.

The high-level indicators in the list below were adopted in 2009 by the state Forum on Monitoring Salmon Recovery and Watershed Health and today still provide information that is used to determine how the salmon are doing and whether recovery plan implementation should be adjusted. Measures of most of these indicators may be found throughout this report.

  • Adult spawners
  • Adults harvested
  • Juvenile out-migrants (smolts).
Watershed Health
  • Land use and land cover
  • Biological health in streams
  • Stream physical habitat
  • Riparian condition
  • Water quality
  • Water quantity (streamflow)
Implementation Indicators
  • Plan implementation progress
  • Funding
  • Barriers to fish passage
  • Hatchery practices
