Snowmelt runoff from thll lower elevations in the basin <br />began about mid-April and melt rtmoff progressed to the htgher <br />elevations during May and June. Because runoff hem the ll1ajor <br />portion of the mountain area in \he North Platte River baain is <br />controlled U.f reservoirs, the flClod hydrographs experiencM. along <br />the North Platte River hem Semir,oe Dam to the confluence with <br />the South Platte River reflect tlte regulated flow conditions. <br />A detailed discussion of the res~rvoir regulation operation during <br />the runoff period is presented ir, the Reservoir Regulation <br />Section of this report. <br /> <br />c. Flood hydrographs. AvaUable reservoir and hydrographic <br />data fo~ the April through July ~noff period in the North Platte <br />River basin are shown on plates 3..5 to 22. The Laramie Ri\rer <br />hydrogra.ph, shown on plate 19, r~presents the ms.jor portion of <br />tributary inflow that occurred it; the North Platte River 'basin <br />between Glendo Dam and the mouth of the North Platte River. <br /> <br />d. Peak discharp;es. Availa.ble peak discharge data tn the <br />North Pl.atte River basin between Glendo Dam and the mouth of the <br />North Platte River for the 1973 flood are summarized in table 8. <br /> <br />24 <br />
