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1975 Forum Report have thus been superseded.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. <br />* Provisional Record. <br />** Derived from Water and Power Resources Service data. <br /> <br />-5- <br />
