Within the park boundaries lies a ghost town that was inundated when Lake Mead first filled up in the 1930's. Once a Mormon settlement, St. Thomas thrived as a stopping point between Los Angeles and Salt Lake City along the Arrowhead Trail.

LAS VEGAS (KLAS) — Television and social media videos of raging floodwaters after Tropical Storm Hilary lead the public to ask, “Does all that water help?” The answer is complicated, but officials say Hilary's direct effect on Lake Mead was “minor” and had more to do with reduced demand than anything else.
According to the website of the National Park Service (NPS), St. Thomas, the dam created Lake Mead, which flooded areas along the Muddy and Virgin rivers. During the early 1930s, Lake Mead began to form, and St. Thomas gradually disappeared under the rising waters.
Downriver towns and major cities would see the most damage, in the event of the dam's physical collapse. Water flows would engulf many towns and growing cities around Mohave county, including Laughlin, Nevada; Needles, California; Lake Havasu, Arizona; and even as far south as Yuma, Arizona, and San Luis Rey, Colorado.
Not exactly. The tropical storm brought nearly a monsoon season's worth of precipitation in just a few days. But that heavy rainfall likely had little effect on Lake Mead's water levels.

Lake Powell and Lake Mead are unlikely to refill for another 50 years - and would need SIX consecutive years of deadly atmospheric rivers to replenish.
Key Points. Lake Mead has dropped by 70% due to droughts in the West and it will take many years to refill again, naturally. The reservoir is vitally important to millions of people as a source of water, electricity, and recreation.
Before the existence of Lake Mead, Lake Mohave, and Hoover Dam, the area encompassing the one and a half million acres of the Lake Mead National Recreation Area was occupied by early desert Indian cultures, adventurous explorers, ambitious pioneers looking for cheap land and religious freedom, and prospectors seeking ...
As much as we clearly wanted it to, Hurricane Hilary couldn't help with that. Its rain didn't reach into the Rockies to sate those soils. And while Hilary drenched areas near Lake Mead, it gained less than a foot of elevation in the days after the storm (it is a big lake, after all, which takes a lot of water to fill).
What happens if Lake Mead dries up forever? If Lake Mead were to run out of water, the Hoover Dam would no longer be able to generate power or provide water to surrounding cities and farms. The Colorado River would essentially stop flowing, and the Southwest would be in a major water crisis.
Did Tropical Storm Hilary Affect Lake Mead Water Levels? Lake Mead's water levels, at a record low last year due to ongoing drought, rose a bit during heavy rainfall from Tropical Storm Hilary. But rain isn't the lake's primary source of water.
It would actually take six more years of heavy rainfall in a row to refill the Lake Mead reservoir completely. Time is ticking to solve the problem before future droughts dry up the lake completely. Without irrigation, farmland like this in California and other western states would revert to the desert.
