4-27 <br />• or dryness of the period of recorded East Salt Creek flows <br /> can be inferred from the much longer records available for <br />the White River near Meeker. In order to determine whether <br />the past 6 years, the period of record for East Salt Creek <br />flows, have been relatively wet or dry, the White River <br />mean annual flow for that period was computed as a percentage <br />of the mean annual flow. Studies were conducted for both the <br />recent past, i.e., the last 20 years (1960 to 1979), and for <br />the entire period of White River records, 1902 to 1979. <br />From 1974 to 1979, the White River has flowed 102 percent <br />of the mean value for the last twenty years, but only 95 <br />percent of the mean value for the longer term, 75-year <br />record. This comparison indicates that flow during the years <br />• 1974 to 1979 was slightly above average compared to the <br />recent past (1960 to 1979), but flow was 5 percent less than <br />average when the longer term climate since 1902 is considered. <br />4.5.3.1.4 Flow Regime of Munger Creek <br />Since no discharge records are available for Munger Creek, <br />or any other East Salt Creek tributary, average flows were <br />estimated from East Salt Creek flows on the basis of relative <br />drainage area. The Munger Creek watershed encompasses 3.9 <br />percent of the entire East Salt Creek Drainage Aasin and, <br />thus, can be assumed to deliver 3.9 percent of the East Salt <br />Creek mean annual flow. Thus the mean annual flow of Munger <br />Creek was estimated as 0.17 cfs. Assuming the same coef- <br />• ficient of variation for Munger Creek as for East Salt Creek <br />
