Tom Ryan of the tvtetropolitan Water District of Southern California and Steven Hunter
of the Reclamation Denver oOlecs agrecd that portions of their reports could be uscd in the
preparation of this paper. The cooperation ofthc Salt Lake City oOlce of the National Weather
Service, River Forccast Center in pcrfonning analyses of the impacts ofprcdicted increases in
precipitation upon runoff\\:as cxtremely useful. Scveral people provided rcviews and comments
on a draft of this papcr including: Don Ostler (Upper Colorado River Commission), Todd
Adams (Utah. Division ofWatcr Resources). Joe Busto (Colorado Water Conservation Board).
and Tom Ryan (Metropolitan Watcr District of Southern California).
