Reclamation Seeks Written Comments on Draft Report on Enlarging Shasta Dam and Reservoir

Shasta Dam study

Stakeholders may submit written comments until Friday, Dec. 28 on the U.S. Bureau of Reclamation’s draft feasibility report on raising Shasta Dam and enlarging its reservoir.

In February, Reclamation released its draft feasibility report which examined the potential costs, benefits and impacts of enlarging Shasta Dam and Reservoir. Reclamation has been studying the feasibility of alternative dam raises ranging from 6.5 feet to 18.5 feet. Raising the dam to those heights would result in corresponding increases in reservoir storage from 256,000 acre-feet to 634,000 acre-feet.  The additional storage capacity would be used to improve the reservoir’s ability to provide colder water for winter-run Chinook salmon during drought years. It also would increase water supply reliability for agricultural and municipal water users in the state, the report asserts.

Reclamation also is studying the alternative to take no action on the dam.

Reclamation has received comments since the draft report was released in February and is now requesting additional written comments from all interested individuals, agencies and organizations.  All comments received will be considered as Reclamation completes remaining engineering, environmental, economic and financial studies and reports.

Reclamation also is preparing a formal draft environmental impact statement on the Shasta Dam and Reservoir enlargement scenarios and will establish a separate formal public review and comment process once that document is released to the public.

A decision to raise the dam and enlarge the reservoir requires complex and intricate analyses, Reclamation stated in a press release. As the decision-making process continues, Reclamation seeks to address public and agency concerns and comply with all applicable federal, state and local laws, the release added.

The draft feasibility report is available on Reclamation’s website at
