What's the Plan to Save Winter-run Chinook in the Sacramento River?

NOAA has developed a "Priority Actions 2016-2020" document outlining their plans to try and recover this rapidly dwindling population.

The Sacramento River winter run Chinook salmon ESU was chosen as one of the eight most at

risk species because it is composed of just one small population that is currently under severe stress caused by one of California’s worst droughts on record. Over the last 10 years of available data (2003-2013), the abundance of spawning winter - run Chinook adults ranged from a low of 738 in 2011 to a high of 17,197 in 2007, with an average of 6,298. The population subsists in large part due to agency managed cold water releases from Shasta Reservoir during the summer and artificial propagation from Livingston Stone National Fish Hatchery’s winter-run Chinook salmon conservation program. Winter-run Chinook salmon are dependent on sufficient cold water storage in Shasta Reservoir, and it has long been recognized that a prolonged drought could have devastating impacts, possibly leading to the species’ extinction.
