Mead elevation 1000 ft is currently the minimum operating level of Southern
Nevada Water Authority's lower intake. Figure 3 -7 shows the probability of Mead
going below 1000 ft is negligible until about 2020. After that, the probability of
Mead being below 1000 ft is above 10% under normal operations and less than
5% under the Hybrid strategies.
