This supplement presents a revised plan to mitigate project effects on wetlands
and terrestrial vegetation in the Closed Basin and other project changes which
have occurred since filing of the FES in 1979. The amount of wetlands and
terrestrial vegetation to be affected is significantly less than believed at the
time of the 1979 FES. Also, the results of pump tests and the vegetation moni-
toring program are discussed. Updated information on waterfowl production and
other bird use is presented. More extensive cultural resource investigations
have been done to determine project impacts. Other project feature changes,
such as conveyance channel a1inement and additional wells, are also described.
The nature of and probable impacts of the revised proposed action are presented.

This supplement serves a dual purpose--administrative-legis1ative action. It
complies with the National Environmental Policy Act of 1969; Clean Water Act
of 1977, Public Law 95-217, Section 404(r); Executive Order 11988, "Flood Plain
