Dim failure inundation maps (except inundation maps are <br />not required for minor dams located in remote areas where there is no <br />develop.ent downstream of the dam): <br /> <br />2. Cross-sections drawn to scale showing water surface <br />elevations at critical sections where structures are impacted as <br />described in the classification of dams. Cross-sections shall show <br />discharge in cubic feet per second, Iverage velocity in feet per <br />second, and structures located in the flooded section: <br /> <br />3. A tabulation of assumed para"",ters including Hannings 'n' <br />values for the floodplain: <br /> <br />4.

A topographical map showing the drainage arel above the <br />dam with the drainage area delineated and noted in square miles; the <br />location of the proposed dam by quarter section, section, township. <br />range, and principle meridian: the bearing and distance from Station <br />0+00 on the dam to a section corner; the name of the stream impounded, <br />or indicate the dam is off stream and name the stream to which it is <br />tributary, or name the drainage basin In which the dam is located: the <br />elevation of the dam crest: <br /> <br />2. A description of the topography, geology. and vegetative <br />cover of the drainage area; <br /> <br />3. A summary of all hydrologic parameters for the method <br />used, the peak inflow design flood hydrograph, volume of flood, and <br />the hazard classification of the dam; <br /> <br />- 13 - <br />
