<br />! <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />1623.001 <br /> <br />Information on storm runoff found in the first two reports (R. V. lord <br />and J. T. Banner) is of little value since the method of analysis and storm <br />frequency used are out of date, although the Banner report does contain <br />a number of photographs and a list of structures found on Spring Creek <br />that could be useful. <br /> <br />The Black and Veatch study was completed using the 2-year, 5-year, 10-year, <br />20-year and 50-year storm events and is probably of little use, although <br />in this report, the idea of using irrigation canals to import flood water <br />into Spring Creek from the north was introduced. <br /> <br />The study done by land and Water Consultants was primarily concerned with <br />the proposed design of the Moore Park detention basin #3 and contains a <br />number of hydrographs routing flood waters through it. This is the first <br />of the studies on Spring Creek that incorporates the 100-year storm event. <br />Analysis of the watershed above the proposed dam is included, along with <br />a table of basin characteristics and a summary of. inflow hydrographs with <br />and without imported flood water. <br /> <br />The Interim Flood Hydrology Report by Resource Consultants of 1977 contains <br />100-year hydrographs for the basin below Moore Park detention facility, <br />with and without importation. This study and the previous one by land and <br />Water Consultants complement each other and form a complete picture of <br />100-year flood hydrology. Revisions to the interim report published in <br />1979 alter the quantities of imported floodwaters downward and make the <br />hydrographs found in the original 1977 report obsolete. <br /> <br />The Feasibility Studies for Diversion of Storm Water Runoff through <br />Irrigation Canals from Mulberry Street to Spring Creek" completed in 1979 <br />contain flow rates expected to enter Spring Creek from outside the basin. <br />This report outlines proposed improvements to irrigation canals that fix <br />the expected contribution to Spring Creek and will need to be included <br />in our analysis. <br />
