<br />. <br /> <br />. <br /> <br />ADMINISTRATION OF THE SDUTH PLATTE RIVER, <br />DISTRICT 2, UTILIZING REAL-TIME DATA <br /> <br />. <br /> <br />In District 2, the Water Commissioner's primary <br />responsibility is in distributing water to senior ditch <br />rights in the reach from Henderson to Platteville. The <br />water supply for these rights comes mainly from water <br />passed through Chatfield Reservoir and inflows from Bear <br />Creek, Clear Creek. and the Denver Metro Sewage outfall. <br />The key index station for the administration of these <br />senior rights is the gaging station, South Platte River at <br />Henderson (PLAHENCO). <br /> <br />. <br /> <br />The hydrograph shown plots real-time discharge data <br />for PLAHENCO for the period June 7-11, 19B7. The most <br />obvious characteristic of the hydr09raph is the flood <br />event occurring on June g. 1987, as the result of a major <br />precipitation event. Flow increased significantly from <br />2000 cfs to nearly 13,000 cfs in less than three hours. <br />The water commissioner was able to alert diverters of <br />these available flood waters for either direct diversion <br />or for off-channel storage. Residual flood water was <br />available for several days after. The ability to monitor <br />these changing flow conditions on a real-time basis allows <br />for more effective distribution of available water <br />supplies. <br /> <br />. <br /> <br />. <br /> <br />Alan Berryman, Division 1 Engineer <br />Keith Delventhal, Water Commissioner.
