The results of these measurements <br /> <br />showed a. conservallve estirrEte for the discharge of the above streams <br /> <br />during the peak of the flooc. of July 16, IS23 to be: for Sane Cree]c, <br /> <br />15,COO cubic feet :per secon(; Oal{ Creek, 11,250 cubIc feE t per second <br /> <br />and DI"J Creek 100l; c1.<oic feet per secone.. 'rhe factors considered in <br /> <br />making the above de termination for Sano. Creek are shovil1 on Drawing Ho. <br /> <br />4 - 9.
