The peal.: daily aver:~<Jes for each <br />-'" <br /> <br />I <br /> <br />measuring station in the seven-year period studied are shown in Table II. <br /> <br />Also shown in this table are the quantities of runoff in terms of <br /> <br />I <br /> <br />inches delivered from the watershed past the stream gage on the peak <br /> <br />:i "" <br />day each year. These peak d';i1.y runoff amounts are presented in <br /> <br />I <br /> <br />hundredths of inches fer each peak streamflow day. The quantity of <br /> <br />I <br /> <br />second feet per day of streamflow, which is equivalent to .01 inch <br /> <br />from the entire watershed, is shown in the left hand column. <br /> <br />I <br /> <br />The maximum quanti-;:y of runoff from snow melt at each station is <br /> <br />emphasized by a small box. Four of the seven stations had their maximum <br /> <br />I <br /> <br />flow in 1968. However, there was an equivalent peak quantity in 1967 <br /> <br />I <br /> <br />at Upper station of Gore Creek. The highest value for any station for <br /> <br />anyone day is shown as .91 inch of runoff fer Booth Creek on June 21. <br /> <br />I <br /> <br />1968. The maximum discharge for the season also occurred on that day. <br /> <br />It was 182 cfs as compared with the average for the 24-hour period of <br /> <br />I <br /> <br />only 148 cfs. <br /> <br />I <br /> <br />The daily cycle of cool and warm temperatures produces a peak streamflow <br /> <br />in the late afternoon or early evening hours from the relatively small <br /> <br />I <br /> <br />watersheds along Gore Creek. During nighttime hours on most days in <br /> <br />.\.-, , <br /> <br />I <br /> <br />the highest flow periods frao snow melt, temperatures arc at or ve1Y near <br /> <br />freezing at the surface of the remaining unmelted snow. During day tine <br /> <br />I <br /> <br />hours temperatures of the ambient air moving past the snow pack may be <br /> <br />20 to 250 wanner than the nighttirr.e temperatures. 1\ general ratio <br /> <br />II <br />i <br />II <br /> <br />-13- <br />
