The diversions on tributaries are those reported <br /> <br />by the water commissioners as being made from river water, and do not include <br /> <br />canal diversions made from reservoir water. <br /> <br />Accretions - Return Flows <br /> <br />An indication of the amount of return flow to a river section may be <br /> <br />obtained by subtracting the measured surface inflow to the section from the S'UlIl <br /> <br />of the diversions and the river outflow from the section. The "accretion" thus <br /> <br />calculated includes, in addition to seepage and surface return from irrigation <br /> <br />diversions, an ,unknown amount of unmeasured surface runoff from precipitation, and <br /> <br />also the effect of channel losses in the river section. <br /> <br />Since it is not practicable to accurately separate these factors in <br /> <br />the calculation, over an extended period of time the average accretions have <br /> <br />generally been designated return flows. <br />
