Protecting Chinook Salmon in California

This project will use a WEAP application linked to model of salmon life cycles to investigate what management options are open to manage Spring run Chinook salmon.

The extent of the spring run in California has been reduced to only a few streams, and those that remain are at grave risk due to climate change. Chinook Salmon are the pinnacle species in the California’s riverine aquatic ecosystems.

Historically these large fish spawned in most of the rivers and streams which flowed into Monterey Bay.

As a result of the diverse hydrologic and climatic conditions, individual streams accommodated genetically different salmon populations, or “runs”. But the enormous amount of hydrologic manipulation in California over the last century has lead to the decline of many of these runs, none more so than the Spring Run.
