Show Peak of floods appear 31 almost simultaneously at tiny point the stream the peak at Greenriver and at Bluff , practically the same day , two days later at Lees ( Perry Ferry ) . ( R . . 153 . . ) The day he started at Greenriver , ( "Utah Utah ) , flow was about 2,300 or 3,000 ( second-feet secondfeet ) . Clyde L . Eddy had somewhere about 10 times as much water when he started . There is ( a' a ) very uniform flow from Oc ¬ tober to ( Alay-very Alayvery ) ( low-in lowin ) general lower than when he was there . A flow of 2,000 , 3,000 , or ( 4,000 4,00-0 ) ; ( second-feet secondfeet econd-feet econdfeet ) on the Green River and the Colorado River is quite a large one . The large ( run-off runoff ) in May , June , and July is from melted snow ; flow decreases until floods in August and September from thunderstorms . ( Thunder- Thunder ) storms rare during October and November , ( prae- prae ) tically absent during December , January , and February . So we have a condition where in a couple of months , or two and ( one-half onehalf ) months 70 % of the water runs off , with the remainder of year low , , ( ex- ex ) cept for frequent cloudbursts . ( R . 154-155 . ) , In rivers with such a rapid ( run-off runoff ) , peak might be fully ( one-half onehalf ) times more than some of ordinary peaks shown on these ( hydrographs hydrograpbs ) . ( R . 155 . ) Dlustration : Saleratus Wash comes in South of Greenriver , Utah . . It Avas dry the afternoon he arrived ; thunderstorm came up at 10 ( o'clock oclock ) that night , Saleratus Wash . was out of its ( ten-foot tenfoot ) banks , , |
