<br />2427 <br /> <br />. <br /> <br />. <br /> <br />below Evans No. 2 Ditch diversion, at the mouth of St. Vrain Creek, <br /> <br />at the mouth of the Big Thompson River and at the Kersey gage, so as <br /> <br />to identify critical or low flow places in the river. <br /> <br />Since all daily flows were tabulated on the day of their <br /> <br />actual occurrences, it was necessary to route the Denver water so <br /> <br />as to account for the two day travel time between Denver and Kersey. <br /> <br />This was accomplished by the successive average method which con- <br /> <br />sists of averaging each daily flow amounts with those for the <br /> <br />preceding day. It was found, after some trial and error, that <br /> <br />successive averages for the Denver flow at Henderson and Ft. Lupton <br /> <br />only gave satisfactory results. <br /> <br />The amount of Denver water tabulated at the critical <br /> <br />points of flow in all cases was, whichever was the lower, the com- <br /> <br />puted flow or the gaged stream flow. The Denver water reaching <br /> <br />the Weld County site (Kersey gage) was reviewed to determine what <br /> <br />portion of this water was exchangeable up to the Burlington Ditch. <br /> <br />The general rules as set forth in Paragraph A, (Narrows to Bijou <br /> <br />and Riverside), were adopted in obtaining the exchangeable water <br /> <br />up to the Burlington Ditch, except in this case, the Bijou, River- <br /> <br />side and other ditch diversions within the Weld County reservoir <br /> <br />were assumed to be served from the reservoir. Presented on Table <br /> <br />3 is a monthly summary of the estimated amount of water that <br /> <br />potentially could have been exchanged up to the Burlington Ditch <br /> <br />with a practical operation of the river under historic flows. <br /> <br />- B - <br />
