Thus, <br />..hile the inclusion of runoff estimates in the table has been made to <br />present a general picture of the amount and distribution of available <br />\later, it is probable that in some cases the solution to specific prob- <br />lems of administration, design, and operation may require the establish- <br />ment of some particular gaging station or the continuation of records <br />at some point of collection. <br /> <br />Accuracy of data. Due to the tendency of most streams in the south- <br />..est to shift from one lo...water channel to another, the records collected <br />at gaging stations are frequent~ classified with accuracy rating of poor. <br />The indicated error of dai~ records may exceed 15-e~, but it is probable <br />that the monthly records are some..hat better and that the annual figures <br />are probab~ fair~ representative of the true flow. <br /> <br />Records computed by comparison with records at some other site are <br />some..hat less accurate than an observed discharge, depending upon the <br />magnitude of the extrapolation. <br /> <br />Records presented as computed from rainfall runoff studies are <br />general~ of an approximate nature. Such data are not intended to repre- <br />sent a chronologically historic flo.. for the calendar months shown; the <br />estimates have their significance in the iU.em1se that if a climatic <br />cycle similar to that of the past were to recur, on an average, the <br />figures of estimated flo.. are representative of the flo.. that might <br />be expected. <br /> <br />3-3 <br />
