Colorado River and Reservoir Management Strategies
Table 3 -1 displays the maximum cumulative shortage for each strategy.
Cumulative shortage refers to the total amount of shortage accumulated up to (and
including) a certain year. The value in the table reflects the maximum for that
year over all 90 traces. Shortage accumulates faster under Hybrid revl because it
is triggered sooner and more often as shown in Figure 3.8. Recall that under the
Step Shortage strategies, the maximum shortage in any one year is 600 KAF.
