Much of the time, the water is smooth and almost glassy. It should be noted that there are strong currents in some places. An interesting feature of the Colorado below Hoover Dam is the cold water. Even in the height of the summer when the water temperatures in Lake Mead are in the '70's, the river will be at least 20 degrees colder. Because the river is fast moving it does not get a chance to heat up and it stays at about 50 to 52 degrees Fahrenheit all year long.
Willow Beach has a convenience store, a launch ramp, boat rentals and marine fueling facilities.
It is recommended that when you visit Las Vegas, drive out here, rent a boat and see Hoover Dam from the bottom. Now that is different. Again, do not take anything for granted, if you want to rent a boat, call the day before. Especially on weekends. We recommend weekdays, because most likely you will have the place to yourself.
