LAKE ROOSEVELT

Lake Roosevelt is the largest lake in the northwest quarter of the United States. Most water in the lake comes from glacial ice and snow high in the Canadian Rockies. The area's climate varies with location - the south experiences hot, dry summers, while the north sees significantly more rainfall that supports Ponderosa pines and Douglas fir forests... Formerly known as Dakota Columbia, Lake Roosevelt Adventures is headquartered at Seven Bays Marina and Keller Ferry Marina. Lake Roosevelt Adventures offers our guests the finest houseboat rentals in the area, access to small boat rentals, a full service restaurant, retail, and the area's only convenience store.
