used in conjunction with a simulation model of the
Colorado River. As the simulation model is run under
varying assumptions and conditions, major economic
impacts related to salinity changes can be observed.
Such economic evaluation will provide some of the
basis both for evaluating salinity mitigation proposals
and for measuring negative external impacts of future
water resource development projects. This type of
analysis is presently required by the Office of

Management and Budget on all federally sponsored
projects.

Continuing work is expected to encompass all
agricultural and M and I users in both the Upper and
Lower Basins as well as the most promising salinity
mitigation measures, in ,order to provide guidance as
to the future development and management of water
resources in tbe basin.
