From the letter:

…we believe that additional actions are needed to reduce the risk of Lake Powell dropping to elevations at which Glen Canyon Dam releases could only be accomplished through the river outlet works (i.e. below elevation 3490′ mean sea level (msl)), or hydropower operations infrastructure at Glen Canyon Dam would be adversely impacted…

… we have recently confirmed that essential drinking water infrastructure supplying the City of Page, Arizona and the LeChee Chapter of the Navajo Nation could not function…

In particular, in conjunction with any potential 2022 Drought Repsponse Operations Plan releases the Department respectfully requests your consideration of potentially reducing Glen Canyon Dam releases to 7.0 maf this water year and providing additional certainty regarding annual release volumes and tier determinations for the 2023 water year.
