<br />The 1973 depletions for New Mexico have been revised since publication of the
<br />Forum Report, "Water Quality Standards for Salinity Including Numeric Criteria
<br />and Plan of Implementation for Salinity Control, Colorado River System." The
<br />values shown in the 1975 Forum Report have thus been superseded.
<br />
<br />Values of Arizona and California are diversions less returns including estimated
<br />unmeasured return flows.
<br />

<br />
<br />~/
<br />!/
<br />
<br />Values for Nevada are gross diversions.
<br />
<br />The estimated uses for Utah have been revised for the years 1973-1979.
<br />
<br />Includes all Lower Basin mains tern reservoirs and Senator Wash. Does not include
<br />net instream losses below Hoover Dam and tributary inflow between Lee Ferry and
<br />Hoover Dam estimated to average 200,000 af/yr and 750,000 af/yr, respectively.
