* California, Arizona and Nevada strike deal with US government to take about 13% less water from drought-stricken [Colorado] river.*

This will surely slow the drying of the Colorado river. Will it be enough to prevent that? We don't know. It depends on whether the atmospheric rivers that now plague California bring enough water to the east side of the Sierra Nevada mountains to keep the Colorado flowing. If not, the trend of increased aridity in the region may continue.
