The greatest improvement in the new draft Uses and Losses Report is
the inclusion of a more complete, and easily understood, Technical
Appendix for the Upper Basin. Unfortunately, data from the Lower
Basin were not detailed in an appendix. The Lower Colorado River
Region relied heavily on the reported accounting for Article V of
Arizona v. California. Unfortunately, these data are not inclusive
of all uses in the Lower Basin. I have suggested that this problem
be rectified ~n the 1986-1990 Uses and Losses Report.

The new draft Uses and Losses Report is much better than the
original draft. Although I see no major problem with it, the
Corrnnission member States are still reviewing it. I suggest that
this updated analysis be forwarded to the states and members of the
Engineering Corrnni ttee for their use.
