Glen Canyon Management Plan: LTEMP DEIS Now Available for Public Comment

Any comment or question can be directed to Eric Swanson (AFC Conservation Chair)


The Department of the Interior, through the Bureau of Reclamation and National Park Service (NPS), has made available for public review and comment the Draft Environmental Impact Statement (DEIS) for the Long-Term Experimental and Management Plan for the Operation of Glen Canyon Dam (LTEMP). The LTEMP would determine specific options for dam operations (including hourly, daily, and monthly release patterns), non-flow actions, and appropriate experimental and management actions that will meet the requirements of the Grand Canyon Protection Act, maintain or improve hydropower production, and minimize impacts on resources, including those of importance to American Indian Tribes.

The DEIS was filed with the Environmental Protection Agency on January 8, 2016, and a 90 day public comment period was initiated with the publication, also on January 8, 2016, of the Department of Interior’s Notice of Availability of the DEIS in the Federal Register. Written comments on the DEIS should be submitted by April 7, 2016.

The DEIS is available for reviewing on the internet at: http://ltempeis.anl.gov/. Compact disc copies of the DEIS are available for public review at the following locations:

  • J. Willard Marriott Library, University of Utah, 295 South 1500 East, Salt Lake City, Utah 84112.

The purpose of the proposed action is to provide a comprehensive framework for adaptively managing Glen Canyon Dam over the next 20 years consistent with the Grand Canyon Protection Act and other provisions of applicable Federal law. The proposed action will help determine specific dam operations and actions that could be implemented to improve conditions and continue to meet the Grand Canyon Protection Act’s requirements and to minimize – consistent with law – adverse impacts on the downstream natural, recreational, and cultural resources in Glen Canyon National Recreation Area and Grand Canyon National Park, including resources of importance to American Indian Tribes.

The need for the proposed action stems from the need to use scientific information developed since the 1996 Record of Decision (ROD) to better inform the public of Department of the Interior decisions on dam operations and other management and experimental actions so that the Secretary of the Interior may continue to meet statutory responsibilities for protecting downstream resources for future generations, conserving Endangered Species Act-listed species, avoiding or mitigating impacts on National Register of Historic Places-eligible properties, and protecting the interests of American Indian Tribes, while meeting obligations for water delivery and the generation of hydroelectric power.
