Blog: Innovative management for Central Valley native fish
Historically, the entire Central Valley of California was a floodplain. In winter and spring, storm runoff and snowmelt would spill over riverbanks, creating vast biologically productive wetlands where aquatic life flourished. This incredible productivity supported a huge fishery in the Central Valley, where we once had one of the largest runs of Chinook in the world. However, as modern day California was developed, the Central Valley’s waterways were re-engineered and channelized to control the floods and divert water for human uses. Today, only 5% of Central Valley floodplains remain intact and three of the four native Chinook salmon runs are listed as threatened or endangered.
