Grand Coulee Dam

Effective July 28, 2021, masks are now required for all employees, onsite contractors and visitors inside agency workspaces and federal buildings — regardless of vaccination status if the facility is within an area that has substantial or high COVID community transmission. These safety protocols are consistent with the Centers of Disease Control and Prevention updated guidance.

The Grand Coulee Visitor Center is open to the public and the “One River, Many Voices’ laser light show has resumed its nightly show.

Grand Coulee Dam tours will not be conducted this year because of CDC recommended COVID-19 guidelines. Visitors will be unable to safely maintain social distancing of 6 feet on the tour buses and dam elevator.
