<br /> <br /> <br /> <br />Annual Report 1985 <br />6 <br />Some historical streamflox data exists for 1982, 1983, and 1984 <br />for S'+IGS-O1. Stations 3'NGS-02 and SLAGS-03 can be compared to some <br />' data collected in 19~+. No previous data is available for SHGS-04, <br />' S'dGS-O1 <br />Txo periods of record xith some length xere collected in 1985. <br />' The first, Parch 9 to April 1 shows an 18 day period xith no varia- <br />tion, this is unlikely for that time of year. It is possible that <br />the stilling well xas frozen for this period of time. <br />' The second period of substantial length xas during the month <br />of October. There xas however a period of 12 days without any fluc- <br />t tuation. One apparent precipitation event during October produced <br />a peak instantaneous flow of 24,2 cfs. <br />' The peak instantaneous flow recorded for 1985 xas 3~.7 cfs. <br />' The minimum flow recorded xas 1.26 cfs which occurred during August, <br />this is the minimum flow xhich can be measured by a 4-foot Parshall <br />' flume. <br />Mean daily flows during Dlarch 1985 compare well with those <br />' recorded for Plarch 1983 the only other period of record available. <br />' The mean daily flows during October are similar to those of October <br />1982, again the only period of record available. <br />' SWIGS-02 <br />The record for this station xas good from July 10 to December 8 <br /> <br />
