This is your semi-regular, repetitive reminder that El Niño and La Niña don’t matter a hill of beans, in statistical terms, for the Colorado River Basin as a whole.

The Climate Prediction Center has issued a La Niña watch. That means cooler temperatures across the equatorial Pacific, which tends on average to influence the North American storm track, pushing storms, on average and in bulk, sorta north. Sorta. Maybe. That means it tends to be a bit drier across Arizona and New Mexico on average, sorta maybe. But as you get farther north, where most of the Colorado River Basin’s water originates, dunno. Hard to say much in a predictive sense, as one says again and again:
