Disadvantages:
"Intense opposition could be expected.
'Plan has major water rights issue.
"Entitlement question of Upper Basin versus Lower Basin.
'Significant losses due to seepage and evaporation.

plan 6-25. Deve~QO Trans-Basin Diversions Into Colorado Rivp.r
Basin.
Category IV

I

This plan was proposed but because of current legislation
prohibiting such trans-basin diversions, no further analysis will
be made.

Plan 8-26. Desalt Uostream Brine Inflows (~itle II Pro;ects).
Cost $38.8 million, TVS 950 points, Category V.

I

I

Brine flows identified to be controlled as ~itle II Salinity
Control Projects would be desalted. The product water would be
returned to the Colorado River for use as substitute water. The
yield is estimated to exceed 116,000 acre-feet/yr. Federal
ownership of the desalted water and right to convey desalted
water through the Colorado River are major institutional problems
to be overcome. This plan would improve the quality of Colorado
River water.

Advantages:
-Improves water quality in the United States and Mexico.

I

Disadvantages:
-aigh cost.
-Major water rights issue.
-Significant losses to the river.
-Significant losses in entitlement.
-More difficult to meet salinity differential.

Plan B-27.
Category IV

ImDlement Municioal and Industrial Conservation.
(No further analysis of this plan is contemplated.)

I

This plan would compensate for loss of return flow by reducing
demand for municipal and industrial (M&I) water because the
Federal Government would underwrite the cost of implementing
conservation measures. This plan does not appear to generate any
new water because most major M&I water distributors are already
stressing conservation among their water users as a means of
forestalling pending water shortages. No yields are anticipated.

I

Advantages:
"Makes better use of existing supply.
