While You’re Out and About

Start & Return Time
Houseboat boarding begins at 3pm on the trip’s start date and houseboats are due back by 10am on date of return. Be timely…$250.00 per hour will be charged for late returns.

We don’t offer early boarding. A friendly neighbor is enjoying the lake on the very same boat that you are itching to take out. Trust us – you’ll enjoy every extra minute at the end of your vacation too!

For the health and safety of all guests to Lake Roosevelt Adventures, pets are not permitted on or around the houseboats. Service animals are however welcome to accompany their owners.

The houseboat has one 140 hp Volvo Penta inboard/outboard engine that burns 4-5 gallons per hour. The larger boats include a generator to recharge the boat’s battery system. Typically, you will need to run the generator 3-4 hours per day to keep the system charged and engine normally burns one gallon per hour. Because these boats have a single motor, they are very economical to operate. The price of fuel is controlled by the National Park Service. And no, we can’t tell you how much fuel cost to consider, because that’s totally dependent upon your escapades on the Lake!

During your orientation, you will be instructed when to turn the generator on. The power meter is color coded (Green-Good, Yellow-Getting Depleted, Red-Charge Now).

Follow the placarded generator operating instructions STEP BY STEP. Many systems can be run for hours on battery power, while certain systems, like the hot tub jets, dishwasher, and air conditioner require the generator to function.


Is there fresh water on board?
Yes, 105 gallons for the Nova & Galaxy Class, and 30 for the Explorer Class for consumption. All other water running in the houseboat (shower, dishwashing, etc.) is filtered lake water.

Emergency VHF Communication
For Nova & Galaxy Class guests, your houseboat is equipped with VHF Marine Radio. This radio is monitored during the day. Use channel 16 for emergencies and initiating contact only. Channel 2 (not 02) is available for weather forecasts.


On the last day of your vacation, your houseboat should be floating outside the log boom at 10:00am. (You will not be allowed to drive the houseboat inside a marina boundary line.) For your safety and ours, we kindly ask that everyone is packed and ready for offload at this time.

When you arrive at the log boom , please call “Lake Roosevelt Adventures Operations” on VHF Channel 16 (Nova/Galaxy) or 509-725-7229, which is the Seven Bays Marina. Our staff will come out and drive you to the dock.
(Please note, the marina does not open until 9:00am, so don’t be alarmed if no one answers prior to that hour.)

Fueling Up
Once at the fuel dock, we recommend sending people to the parking lot to retrieve cars and take them over to the houseboat dock – it’s easiest this way.

Things to do:

  • Take all trash off the boat and to the dumpster located by the boat launch)
  • Pay our friendly team members for fuel
  • Finish unloading
