though rainfall is low.. what you are also finding is the stupid politics of the water authority that gives out water "quota's" to counties, which the water authorities has for years been pretending more water exists than actually available to ensure california gets a nice amount of quota for water that does not exist
however because it awarded quota's to states that then divide it up to counties that then divide those quotas to farmers, where those farmers dont want to lose those quota's rate next year and so they have to fully use up their water amount this year to retain that rate. (it doesnt benefit them to save water) so they plant silly produce like nuts and avocado's that waste more water. just so they can use up their quota to retain their quota rate for the next year..
this leads to more water being sent to upstream counties which then means by the time the river flows down stream there is less water left.
3 months ago. the water authority demanded cuts to the quotas for ONLY arizona and nevada..
meaning good old california get to have as much as they want(quotad to have)
this meant that the cut to the quota's left some farmers with less water. in arizona.
yet the californian vineyards got to keep making their wine without exclusions

nevada had to cut back to give more to califorina so that california can keep going, but meant arizona had to cut back as there were obligations that there needed to be some water left south of arizona
its funny how they say nevada and arizona are experiencing a drought of the colorado of decades .. yet california only 3 years..
and lets not get started on the fact that nevada, california and arizona are naturally desert states, where by there is a stupid over population of people on land that meant to be uninhabitable naturally
gotta love how the water agencies shuffle quotas around to give favourable amounts to certain locations and unfavourable limits to others OF THE SAME RIVER, and then say "blame climate"
if they for the last 2 decades actually measured water yields of reservoirs and then done a proper % split of amount per state. they might actually have had a better share and used less over all to keep some of the reservoir water locked in. instead of sending it all to california to grow nuts and avocados
its basically 80% bad math of quotas cause and 20% due to less rainfull to cover the bad math up
