As the flow of a stream is variable iom v.-ar to v ar, estimates of future Mow can be made only from a Btudy of observations covering several years. The rapid increase in the development develop-ment of the water resources of the United States has caused a, great de mand by engineers for information in regard to the llow of streams, as it is now generally realized thai the failure fail-ure ot many large power, irrigation, and other projects .has been due to tin-faei tin-faei thai plans wore made without sufficient suf-ficient trustworthy information in re ! speet to the water Bupply. ; Owing to the broaq acope of these investigations and, the length of time they should cover in order that the records may he of greatest vain., it is in general inuiosilde for private' inl vidnals to rolf.-ct the neeessarv data, j and aS many of the streams traverse more than one Stale this work docs not properly fall within the province of the State authorities. The I'nited States Geological Survey has therefore, by means of specific appropriations by Congress, for several years past made systematic studies of stream flow, with a view to ultimately determining all the important features pertaining to the flow of the principal streams ot the country. In carrying on this work stations sta-tions are established on the streams and maintained for a period long enough to show their regimen or gen oral behavior. When a record thai is sufficient for this purpose has been ob- tained for any stream, the work on that stream is discontinued. The order I in which the streams are measurod is I determined i the degree of their im-portanee. im-portanee. la 1906 the regimen of flow was studied at about 700 Stations distributed distri-buted along various rivers, and data , in regard to precipitation, evaporation, , water power, and river profiles wore collected in manv sections of the country. coun-try.
