High level indicators of fish population health:
– Abundance estimates
– Survival rates
– Recruits per spawner
– Proportionate natural influence
Local Scale Data
Summarized, local-scale data that closely resemble data as originally collected in the field:
– Abundance indexes and estimates
– Hatchery returns
An archive of various stand-alone fish, habitat, water quality, research, and other data sets that don’t fit into our standard databases.
Maps and GIS Data
Data available via a map-based interface.
– Fish distribution
– Migration barriers
– Local-scale data also found via “Data Query”
– NPCC’s “Protected Areas”
– Hatcheries & ponds
– Fish passage infrastructure
– Fish traps
– PIT tag detection sites
– GIS layers
Habitat Evaluation Procedures (HEP)
The HEP data set is an accounting of habitat losses due to hydroelectric development, and habitat gains / protection funded by Bonneville Power Administration as mitigation. These web pages and searchable repository have most of the documents related to this survey effort.
Protected Areas are stream reaches where the Northwest Power and Conservation Council determined that hydroelectric development would have unacceptable risks of irreversible loss to fish and wildlife.
