Does the Bureau of Reclamation's <br />current model present an overly <br />optimistic view of future conditions? <br />OR <br />Are the estimated probabilities of <br />occurrences of events such as <br />Lake Powell dropping below <br />minimum power too low? <br />7 �E <br />Reclamation's model uses estimated virgin <br />flows from 1907 through 1996. Trace 1 begins <br />in 1907. Trace 2 begins in 1908, then wraps <br />around to 1907. Trace 47 begins in 1953, then <br />wraps around to 1952. This process generates <br />lots of data from which the model calculates <br />percentiles and probabilities. <br />Future hydrology of the Colorado River can be <br />accurately described by the 90 year record. <br />
