Folsom Dam Water Control Manual update out for public review

Published June 7, 2017

SACRAMENTO, California – The U.S. Army Corps of Engineers Sacramento District released a draft environmental document today addressing the proposed Folsom Dam Water Control Manual update. The Water Control Manual outlines specifications for flood storage space and reservoir releases when water encroaches into the flood storage space.

The draft Supplemental Environmental Assessment/Environmental Impact Report includes an update to the operation rules for Folsom Dam, incorporating the flood risk management and dam safety benefits of the Folsom Dam auxiliary spillway project, also known as the Joint Federal Project. The JFP includes a new control structure and a 3,027-foot-long spillway that will work in conjunction with the main dam to manage releases from Folsom Reservoir.

The draft SEA/EIR and draft Water Control Manual are available for review on the project web page at

Public meetings are scheduled for June 14-15, 2017, to allow the public to learn more about the proposed update, ask questions of Corps staff and to submit comments. The Corps is accepting comments until July 21, 2017.

The public meetings will be held:
