t <br />1 <br />1 <br />r <br />i <br />t <br />IV. Climatic Factors <br />Streamflow and Mean Temperature: <br />Figure 1 illustrates the relationship between streamflow and temperature. The intent of Figure 1 was to see if <br />there were any type of relationships between peak flows at Cameo and mean daily temperature at Glenwood <br />Springs, as way of estimating the timing of the streamflow peak. As Figure 1 illustrates, it appears that in 1998, <br />approximately four days after the mean temperature reaches 60°F at Glenwood Springs, peak flows at Cameo <br />occur. <br />Figure 1 <br />I <br />d <br />Cl <br />A <br />Comparison of Streamflow Cameo and Temperature ?

As indicated by Figure 2, the peak occurred shortly after the snow water equivalent dropped below <br />10 inches or approximately one month after maximum snow water equivalent occurred. <br />6
