Don’t Just Take Our Word For It

 
 

California has a water crisis. C-WIN is the best option to fix it. They’ve been committed to this issue for decades, and because of their vast experience, they’re highly successful at the policy level. No organization is more dedicated to water equity in California than C-WIN.

— Judy Stewart,
C-WIN Supporter and Daughter of actor Jimmy Stewart

C-WIN is the only organization fighting for the equitable distribution of California’s water. They have achieved remarkable results…and will not compromise bedrock principles.

— Huey Johnson,
former California Secretary of Resources

California does not have a water problem, it has a water management problem. We started CWIN with two goals: to hold those accountable to manage this precious resource fairly, and to be a voice for the fish and game that are directly impacted by our actions but don’t have a voice.

— Dorothy Green,
founder of Heal the Bay and co-founder of C-WIN
