IF YOU ALREADY SCHEDULED A POWERHOUSE TOUR—PREPARING FOR YOUR VISIT:
What they offer on the tour:

• Hydropower: Most of their tours focus on how they generate electricity and getting the power from their powerhouse to your house. You may tour inside the powerhouse.
• Salmon: They also offer a variety of programs about salmon (life-cycle, adaptations, bypass routes at the dam)
• Navigation: You may visit the navigation lock.
• History: Bonneville is a National Historic Landmark with a rich history starting during the Great Depression, through World War II, and it continues to provide clean renewable power and efficient river transportation.

What to bring on the tour:

• A roster of everyone who will enter the powerhouse on the tour. Include first and last names of adults but only first names of children. Because of security concerns, visitors may be required to show ID, and it is not possible to cross the entire dam.
• Appropriate clothing and footwear for the weather.
• "Print out the "After Your Visit" form, complete it and leave with one of the rangers at the end of your program."

What NOT to bring:

• Backpacks or large purses. Backpacks with medical supplies are allowed but will need to be checked upon arrival.
