Show 57 ( Oompl Compl ) . ( M-6 M6 ) . No . 88 , is a compilation of stream flow characteristics of several rivers at base ( gaug- gaug ) ing stations . ( R . 255 , 260 . ) These tables show the yearly ( run-off runoff ) ; mean monthly ( run-off runoff ) ; minimum days for each month ; maximum , ( run-off runoff ) for each month ; for all of the years . Then there are ( defici- defici ) ency tables showing the number bf days of each month the flow has been less or more than certain amounts . ( R . 256 . ) Fully ( nine-tenths ninetenths ) of all the figures given are based ( on oil ) official figures ; a ( com- com ) pilation of high , low , stream flow records , arranged by months , years , and stations . ( R . 256-257 . ) It / is a computation showing the discharge in ( second- second ) feet throughout the year compared with the mean . annual discharges ( R . 257-258 ) , and are the daily mean ( maxinrums maxim-Luns maximLuns ) , minimums , and variations of discharge of each station ( R . 259-260 ) . For instance ( he lie ) shows in the report the ( mean nlean ) annual discharge of the Colorado River at Lees Ferry , at page 39 , for the years 1922 and 1928 what the mean annual discharge has been , what the mean annual ( run-off runoff ) has been , what the minimum day has been , what the maximum day has been , and how the discharge has varied throughout the period . For instance , in ( 1925 -1925 ) the mean ( run-off runoff ) was only 58 per cent of the normal . In 1922 it was 16 per cent above ( normal norinal ) . - . In other ( words iiiords ) , that is just a method of computation to show what the discharge ( was -was was ) throughout that year compared with the mean . . ( R . . ( 257-258 257-2,058 ) ) Where any variations axe referred to by him the figures that lie gives indicate that |
