Colorado, Hawaii and Water

Learned from an interview with outgoing governor Bill Owens that Colorado and Hawaii are the only two states that are independent in terms of meeting their water needs. Every other state has to share water from elsewhere outside their state. I didn't listen to the whole interview, but I really thought that was an interesting fact. Hawaii, the issue is obvious. They have to be independent because there is no pipeline. Colorado has an abundance due to the Rocky Mountain snow and the associated rivers.
