This procedure allows the snowmaking operators to determine how much <br />water can be pumped over and above the minimum streamflow requirements. <br /> <br />f <br /> <br />,- <br /> <br />For illustration purposes, assume that the Water Talk network reported that the streamflow at the <br /> <br />East River at Almont gage was 65 ets, <br /> <br />V = 0,16 (65) = 1.7 <br />V = 12.1 cfs <br /> <br />The projected flow at the snowmaking site is 12,1 ets. <br /> <br />The ~o;'elations Of streamtlow behYee~ 'th~'t,.;~ sites ~s defi;;d" by th~ab~ve;quatio;; \.ovm ~ha~1lt <br />'~er . timi. For instance, increased municipal water use in the upper Slate and East River <br />associated with growth in the Crested Butte region could affect the existing correlation.

Extreme temperature, heavy snowpack and remote site combine <br />to create difficult operation and maintenance procedures, Further, ice cover on the river invalidates <br />established stage/discharge relationships and provides unreliable estimates of streamflow, <br />Alternative gaging procedures are recommended, <br /> <br />r <br /> <br />l <br /> <br />" <br /> <br />4 <br />
