<br />5 <br /> <br /> <br />0908 <br /> <br />this station from October 1959 through September 1964. No correc- <br /> <br />tion was made for Busk-Ivanhoe diversions above the gage as these <br /> <br /> <br />diversions should be of the same pattern and magnitude during the <br /> <br /> <br />runoff season for which discharge is being predicted. For water <br /> <br /> <br />years 1965 through May 1968, discharge at the gaging station on the <br /> <br /> <br />Fryingpan River near Ruedi, Colorado, was corrected for Rocky Fork <br /> <br />flow and used as Fryingpan River flow at Ruedi, Colorado. Rocky <br />Fork flow was estimated from spot measurements. After May 1968, <br /> <br />when storage began at Ruedi Reservoir, the actual inflow computed <br /> <br />from measured outflow and change in storage was used, <br /> <br />Using historical data, a probability curve for Ruedi inflow was <br />computed by the modified California method; it is shown on <br />Exhibit l, Annual inflow of a magnitude equaled or exceeded 50 per- <br />cent of the time was considered the most probable inflow, that with <br /> <br /> <br />a 90 percent chance of being equaled or exceeded was considered to be <br /> <br /> <br />the reasonable minimum, and that with only a lO percent chance of <br /> <br /> <br />being equaled or exceeded was considered the reasonable maximum, The <br /> <br />October through March inflow was distributed according to the average <br />1960 through 1969 distribution pattern for this period, After <br />October through March inflow was subtracted, the remainder was dis- <br />tributed between the months of April through September according to <br />a distribution pattern of actual years that fell near the lO, 50, <br />and 90 percent chance points. <br />
