Like most desert locales, Lake Mead National Recreation Area south of Las Vegas doesn't receive a lot of rain, and there's no question the area is in the midst of a serious drought, but when rain does fall, it can sometimes be too much of a good thing. A flash flood on Monday afternoon caused nearly $1 million of damage at Callville Bay, and that area and the Callville Bay Access Road have been temporarily closed to all park visitors while clean-up and repairs are underway.
