Day 11 of the Page Utility's hydropower-share slide. General manager Bryan Hill's slide deck, shared with Page residents at an April 30 town hall and re-circulated by the Arizona Republic Friday, projects the utility's share of generation drawn from Glen Canyon Dam falling from 40 percent in 2025 to 20 percent by August 2026.

Yesterday's paper carried the slide as the household receipt the basin's collapse generates. Day 11 adds the calendar. Glen Canyon's minimum power pool sits at 3,490 feet of elevation. Lake Powell on Friday read 3,525.95 feet — a buffer of roughly 36 feet. At current release rates and projected inflow, Reclamation's modeled trajectory hits 3,490 feet sometime between mid-August and early September. Below 3,490 feet, water still flows through the river-outlet works, but the turbines stop spinning. [3]

The Page Utility, which serves about 7,500 customers in northern Arizona, would replace the lost generation with market purchases at Mountain West summer rates — roughly four times its current cost basis. Hill has told the Page City Council that residential rates would have to rise an average of 18 percent in 2027 if the August power-pool scenario lands as modeled. The Western Area Power Administration has not yet released its allocation guidance for fiscal 2027.

The 40-to-20 slide is the household number the basin's hydrology produces. Reclamation 6E is the operative scenario.
