<br />2 d 3 are reversed <br />Note: Pages an <br />2 <br /> <br />The adequacy of storage as developed here is based on evaluation of the <br />frequency of natural low flow that was partly developed in Technical Report <br />No.2, The natural low-flow occurrences are used to develop a mass curve of <br />inflow to be expected at a selected frequency, and this curve is then used to <br />determine the storage required to sustain selected rates of gross outflow, <br /> <br />The gross rates of outflow for different reservoir capacities presented in <br />this report represent the outflow resulting from redistribution of natural flow <br />by storage. No attempt is made to indicate what portion of this gross outflow <br />must be assigned to evaporation and seepage losses, Such losses must be eval- <br />uated by the design engineer with full consideration of the specific features ap- <br />plicable to the projects under investigation. <br /> <br />Investigators frequently require streamflow data at places where no gaging <br />station records have been obtained. To help meet this need, procedures for <br />estimating storage requirements at ungaged sites are outlined and illustrated. <br /> <br />The order of presentation in this report is first to present data on fre- <br />quency curves of multiyear low flow; second, to develop and present data on <br />storage requirements; and third, to explain the variations in the outflow- stor- <br />age relations, so as to provide a means of estimating storage requirements <br />when only meager data are available at the site. An appendix contains details <br />of the development of low-flow frequency relations for those readers concerned <br />with the theory and method of analysis. <br /> <br />ACKNOWLEDGMENTS <br /> <br />This report has been prepared as part of a cooperative program between <br />the Kansas Water Resources Board and the U. S. Geological Survey, It was <br />prepared in the Survey district office in Topeka under the administrative di- <br />rection of Elwood R. Leeson, District Engineer until succeeded in September <br />1961 by Edward J. Kennedy. Clarence V. Burns, Hydraulic Engineer, was in <br />charge of computations and preparation of the storage-requirement curves. <br /> <br />Robert L, Smith, Executive Secretary of the Kansas Water Resources <br />Board, directed and guided the scope and content of this report toward the goal <br />of providing information useful to the development of the water resources of <br />the State. <br /> <br />Acknowledgment is made of the helpful advice and criticism of the Wash- <br />ington staff of the U. S. Geological Survey, particularly Clayton H. Hardison, <br />Chief, Hydrologic Studies Section, who developed the methodology used in an- <br />alyzing the recurrence of low flows for periods of more than 12 consecutive <br />months and who advised on many of the other technical problems involved in <br />this study. <br /> <br />Streamflow records that supplied the foundation for this report were col- <br />lected by the U. S. Geological Survey through cooperative programs with the <br />State of Kansas, the Corps of Engineers of the U. S, Department of the Army, <br />and the Bureau of Reclamation of the U. S. Department of the Interior. <br />
