Conclusions• Santa Barbara County: boom or bust
hydrologic cycle
• Drought beyond November 2015: bigproblems
• El Niño: looking good but ….
• Climate change: expect extremes(the new norm)
• Human consumption: reduce,update, reclaim and be creative- Desalinization: not sustainable
• Future: conserve and think-act dry
