Federal officials say they've come up with some proposals on how to manage the flow of water at Glen Canyon Dam. KJZZ’s Al Macias reports.

AL MACIAS: The timing and volume of water released into the Colorado River from the Glen Canyon Dam in Page affects hydroelectricity, beach recreation, native fish and archaeological sites in the Grand Canyon.

The U.S. Bureau of Reclamation and the National Park Service have been gathering input on what they say is the first comprehensive review of dam operations in 15 years.

Possible changes to those operations and other actions proposed by the Department of the Interior are being evaluated

The agencies will produce an environmental impact statement with proposed changes.

A two-day meeting in Flagstaff is scheduled next week to present those plans to the public and to solicit input.
