Platte River at Overton have been estimated using a <br />computer model developed by the Bureau of Reclamation which simulates <br />the operation of .facilities located on and along the Platte River and <br />its tributaries between Lewellen, Julesburg, and Overton. Flows <br />assumed for the pre-Narrows conditions were represented by a "near <br />future condition" of development upstream of Lewellen and within the <br />modeled reach of the Platte River. Historical flows of the South <br />Platte River at Julesburg were assumed to represent the pre-Narrows <br />flow (USBR, 1976). <br /> <br />ExMbit2showsthe.,a,verage,annua.l ,January-April, and May-August <br />flows at various locations within the modeled area for the period <br />1947-1970 under the pre-Narrows condition. <br /> <br />28 <br /> <br /> <br />"',' <br /> <br /> <br />".......
