Huh?
Since all the usable water in California goes through dams the volume is known pretty precisely.
The only undammed rivers are minor ones up on the north coast, where there's no practical route up over the Coast Range to the urban or ag users hundreds of miles away who need more. (I think there is one tunnel that does send water over to the Central Valley).
Then downstream in the San Francisco Bay and adjacent inland delta, water quality is closely monitored because the volume arriving is barely adequate to keep salinity low (so the farmlands there aren't destroyed by salinity) and to save what's left of natural aquatic life. The 'trash' small fish are the basis, feedstock, for the larger bass, salmon, etc that are declining drastically.
Winter floodwater in wet years goes to the ocean unused but the rest of the time water volume and quality throughout the state are precisely managed.
Colorado Delta. Where is the water that started out in the river?
