<br />p~esented. These curves are located at the surveyed cross sections <br />which were not used In computing water surface profiles. The data <br />presented by these curVes 15 based upon relationships developed f~om <br />physical characteristics of the respective cross sections and 1973 <br />flood data. A detailed stUdy may ShOw significantly different results. <br />The flooded area plates show photographs of the flood of May 19n. <br />The locations of observed high water marks from that flood are also <br />shown. These plates also show the limits of the lOa-year and 500~year <br />floods at each cross section as determIned trom the water surface <br />profiles or elevation-<lischarge curves. In cases where surveyed <br />cross section information was extended by using U. S. Geological <br />Survey 7.5 minute quad~angle mapping, an asteriSk (.) denotes that <br />the I imits of the loo-year and SOO-year f IcodS a~e approximate. The <br />loca"tlon of these flood limits at points benlSen the cross soctlons <br />where water surface profIles are presented can be determined by <br />selecting the proper water surface elevation from the water Surface <br />profiles and establish that point on the flood plain by su~vey. <br />Similarly, flood characteristics at points t>etW"fln cross sections <br />where water surface protiles are no"tpresented can bees"timated by <br />noting tho elevation dlfferonces botween the desired flood and the <br />IQ13 f!~ ~~ th~ ~1~vatlon-disch~rS~ cury~~ ~~d ~pplyT~2 t~~~ <br />relationshIps to the flood Characteristics as viewed on the 1973 <br />aerial photos at the desired location.
