<br />liThe 1973 depletions for New Mexico have been revised since publication of the Forum
<br />Report, "Water Quality Standards for Salinity Including Numeric Criteria and Plan of
<br />Implementaiton for Salinity Control, Colorado River System". The values shown in the
<br />1975 Forum Report have thus been superseded.
<br />
<br />1!Values for Arizona and California are diversions less returns including estimated
<br />unmeasured return flows.
<br />3/
<br />- Values for Nevada are gross diversions.
<br />
<br />i/The estimated uses for Utah have been revised for all years shown since the third
<br />I
<br />Annual Progress Report.
<br />5/ '
<br />- Does not include net instream losses below Hoover Dam and tributary inflow between
<br />Lee Ferry and Hoover Dam estimated to average 200,000 af/yr and 750,000 af/yr,
<br />respectively.
