> In 2020 federal memo and regulatory changes under Trump's first administration to send more water from Northern California to Central Valley agriculture via federal projects were ignored by the governor of california, and instead of allowing the water to flow into southern california ... had he done what the current administration forced him to do, there would be no drought in 2020, there would be no empty reservoirs in 2020.

How would diverting water from Northern California, where drought was the worst in 2020, to the Central Valley possibly end the drought?

Filling up reservoirs that are upstream by moving water downstream sounds like quite the magic trick.
