Show 983 The chart ( Compl . Exh . 496 ) tends to show that , ( there -there there ) was a fill of 1 to 2 feet between the date of the lowest line and the date when lie completed the highest line . ( R . 3828-3829 . ) This exhibit shows greater variances in the amount of scour and fill , but they were based on three points of soundings across the river , whereas this other one ( was vas ) based on nine points of soundings . Here , on August 13 , it was ( 0,2 0.2 ) of a foot on the gage above zero . On July 29 it was ( at -at at ) 6.4 above zero , ( showing sbowing ) that between the 29th of July and the 13th of August there was a scour of a little over 6 feet at that particular point . It had washed out that channel , or the bottom , rather . " Q , What does the zero of the ( gage gatre ) denote ? ( ( E R ) . 3829 . ) ( "A A ) , It has no significance , except as a standard for reading the level of the water . In other words , it does not mean on the gage , where it reaches zero , ( that -that that ) that is the bottom of the bed , but it means a reference ( point-something pointsomething ) that is standard . " He took the ( depth dept-h depth ) of the water to make up the charts . - This particular zero mark has no bearing on ( ques- ques ) tion of where the bed was ; it ( shows shoivs ) the amount of scour between those two intervals . He made the soundings there . For instance , if he had a gage height of 14.4 feet and the sounding at that particular time at that particular point was 14.2 , the difference between 14.4 and 14.2 is . 2 ( or % 0 ) of a foot , ( which vhich ) gives him something of a basis for locating ( his 'his his ) points . For instance , take that day in there , |
