This should provide a better <br />perspective on the relative inflow contributions. <br /> <br />I have also provided 2 sets of hydrographs for these inflows: <br /> <br />the first set plots all 39 values for a particular month, <br />showing the general distribution and extremes occurring for a <br />given month <br /> <br />the second set is a time series plot of monthly flows for <br />the 39 year period; this provides a picture of zero flow <br />occurrences in relation to flow patterns within and among <br />years. <br /> <br />For Taylor River inflows (Section D), I have gone through an <br />exercise similar to that done for East River and Ohio Ck. <br />inflow modifications: <br /> <br />long term yields for INFL33".34, 35, 36, 37A, and 37B as <br />obtained from initial estimates were retained; inflows were <br />redistributed following Taylor River at Almont core station <br />flow patterns; comparison summary statistics and hydrographs <br />of average monthly flows for initial and revised estimates are <br />included. Application of this distribution pattern el~minates <br />intermittent zero flow occurrences in INFL35, 36, 37A, and <br />37B. <br /> <br />EXDanded Network: <br /> <br />I am in the process of looking at some of the expanded network <br />inflows identified as having zero flow occurrences (Table 2 in <br />notebook) : <br /> <br />Upper North Fork: ENFL8, 9, 10, and 11 -- <br />will look at revised flows obtained by redistribution <br />of flows using "Muddy Ck. at Bardine (09131500)" pattern <br />
