The Coordinated Assessments (CA) Project develops and shares "high level indicator" data for fish populations.  These high level indicators provide information on the health of whole fish populations:  their sizes, viability, and integrity.  Participants in the CA project include the fish and wildlife agencies and tribes, regulatory and funding agencies such as NOAA Fisheries and Bonneville Power Administration, and others.


The initial effort of the project has focused on the development of a Data Exchange Standard for four salmon and steelhead population indicators including natural origin spawner abundance, natural origin smolt to adult return rate, and natural origin recruits (adult and juvenile) per spawner.

CA is coordinated by the Pacific Northwest Aquatic Monitoring Partnership (PNAMP) with support from StreamNet.  Oversight is provided through the Coordinated Assessments Planning Group which consists of representatives from the states, tribes, and federal agencies.  Facilitation and support are provided through the Coordinated Assessments Core Team.  Nearly a hundred biologists and data managers across the Columbia River basin participate in CA, representing nearly all agencies and tribes with an interest in anadromous fish management and recovery.


CA has developed data describing several indicators of natural origin salmon and steelhead population health, including spawner abundance, presmolt abundance, outmigrant abundance, smolt-to-adult return rate, and adult and juvenile recruits per spawner, as well as proportionate natural influence (PNI) of integrated natural / hatchery populations.
