Yeah, your numbers are not different, just framed differently. If you scroll down, you'll see the "More than nine million acres of farmland in California are irrigated, representing roughly 80% of all water used for businesses and homes." number i cited. Not sure you can necessarily do a lot about the 50%, but maybe worth trying - my (ignorant) understanding is that a lot of it is in areas where it would not help. You can also see that urban water use has fallen like a rock already.. In the past 2 decades, per-capita use went from 230 gallons per day to 146 gallons per day - people have already cut their water use by 30%.
