<br />a. The Town of Wiggins is 10catE!d on an old alluvial fan <br />of Kiowa Creek. The apex of the fan (canyon mouth) is lo- <br />cated in section 32, T3N, R6C1W, approximately 4 stream miles <br />upstream of Wigl;Jins (See Figure A-2) . Flood flows em an al- <br />luvial fan char.3.cteristically take different flow pat:hs each <br />time there is a major flood. FactClrs that effect the flow <br />path of a flood wave across an alluvial fan include, flood <br />magnitude, dep':lsit formations from previous floods and the <br />ability of the flood. to erode new channels. Deposit forma- <br />tions are laid down over a period of decades or centuries. <br />Using a 1950 'topographic map, it appears that flood flows <br />could easily flow north from section 32 t;oward the BNRR em- <br />bankment approximately 2.0 miles sou'l:hwest; of Wiggins. Flood <br />flows could then overtop the BNRR, or flo., northeast along it <br />back towards wiggins, depending on the railroad embankment <br /> <br /> <br />oJ.' <br /> <br />FIGURE A-;?'.. <br />WIGGINS AREA HAP <br /> <br />32 <br />
