As shown in Figure 3 -4, the probability of going below power pool at Lake Mead
is lower under the Hybrid strategies due to balancing releases from Powell. The
probability of being below power pool under Hybrid revl is nearly 15% lower
than Powell normal operations. The difference between the Hybrids is explained
by the amount of balancing releases — there is more water released to Mead under
Hybrid revl because balancing starts at 1100 ft instead of 1075 ft like Hybrid
Original.
