These endangered and threatened national treasures face challenges from overfishing and habitat degradation. We mitigate for these pressures by producing more than 60 million salmon and steelhead nurtured in our hatcheries every year.

This fascinating prehistoric fish is in substantial decline in recent decades due to passage barriers, poor water quality, and more. The native Pacific Lamprey (Entosphenus tridentatus), like salmon, migrate to the ocean and then back upstream to spawn.

This tough little fish survives in many habitats including desert, yet faces challenges for survival. Redband trout (Oncorhynchus mykiss spp.) are a species of concern that are now protected under a multi-state conservation agreement.

Coastal cutthroat trout (Oncorhynchus clarkii clarkii), a species of concern, have a complex life history and need a variety of habitats to thrive. Their survival is challenged by forest management practices and estuary degradation.

Bull trout (Salvelinus confluentus) are more sensitive to increased water temperatures and poor water quality than many other salmonids, so stream and habitat restoration efforts are particularly important for this threatened species.

Lake Sammamish Kokanee (Oncorhynchus nerka) population numbers have declined rapidly over the past decade. 2012 saw exciting returns of kokanee salmon to Lake Sammamish, Washington.

Seven species of freshwater mussels inhabit the streams and lakes of the Pacific Northwest. Populations are declining due to habitat destruction and loss of host fish species. As filter feeders, freshwater mussels can both improve water quality and be used as indicators of water quality.
