HLI List

High level indicators (HLI) are derived metrics of fish population health. The indicators are compiled by states, tribes, federal agencies, and contracted organizations that monitor salmon and steelhead in the Pacific Northwest. These are not raw data or index counts, but derived estimates based on NOAA population groups and best available science.

In some cases, when a population is selected, there may be associated Fish Monitoring data sets available to view by clicking the activated Trends button. These related data may or may not have been used for preparing a particular indicator. Please see the metadata section in the HLI download data set for specific metrics and methods used to produce an indicator.

Use of any CAP HLI data falls under the Data Policy and Agreements.
