“ … we are standing on dry grass where there should be five feet of snow. This historic

drought demands unprecedented action.”

Following the lowest snowpack ever recorded and with no end to the drought in sight, Governor Brown

issued an Executive Order on April 1, 2015 mandating substantial water reductions across the

state of California.

Exceptional Drought Covers 44.3%

Key Regional Water Management Challenges

Recycled Water Use

Maximizing beneficial RW use is key to sustainability

53,880 AF of recycled water produced in FY 14/15

Obligation to discharge 17,000 AF/yr to Santa Ana River
