Restoring Yosemite's Hetch Hetchy Valley principally requires improvements to San Francisco's water system and replacement of some of its hydropower. Returning the valley to Yosemite also raises questions about how to manage and encourage its physical restoration as well as what to do with the O'Shaughnessy Dam itself.

Restore Hetch Hetchy lays out many alternatives, but acknowledges that it will ultimately be the purview of San Francisco to decide how to improve its water system and of the National Park Service, with public input, to determine how to manage the restore valley itself.

Nevertheless, the following reports provide a wide of potential answers to these questions.
