The satellite <br />monitoring system provides real-time data from the gaging <br />stations, South Platte River below Strontia Springs <br />(PLASTRCO), and South Platte River at Waterton <br />(PLAWATCO). PLASTRCO monitors releases from Strontla <br />Springs. Reservoir. PLAWATCO monitors inflow into Chat- <br />field Reservoir. Both stations are essential in reservoir <br />regulation and In accounting. Below PLASTRCO, the Denver <br />Water Department exercises senior water rights of up to <br />2DO cfs by diverting flows through the Highline Canal and <br />the Denver Pipeline. Although neither of these two diver- <br />sions is monitored directly by the satellite monitoring <br />system. diverted flows can be indirectly calculated by <br />subtracting the streamflow being measured at PLAWATCO from <br />the streamflow measured at PLASTRCO. <br /> <br />The hydrograph shown plots real-time discharge data <br />for PLASTRCO and PLAWATCO for the period July 10-14, <br />1987. The table lists the mean daily discharge for both <br />stations for each day along with the net difference in <br />discharge between the two stations, considered to be the <br />amount of water diverted by Denver. <br /> <br />Alan Berryman, Division 1 Engineer <br />Kenneth Salzer.
