Human remains have been discovered at Lake Mead in Nevada after water levels at the vital reservoir reached a record low this month.
Las Vegas resident Dianelis Molina Cruz and her friends made the discovery on August 16 along the shoreline of Boulder Beach, a popular recreation spot inside the Lake Mead National Recreation Area, roughly 30 miles from the Las Vegas Strip.
Cruz told investigators that a friend's daughter was playing in shallow water when she came across the lower jawbone of a person, complete with teeth and dental fillings.
Beachgoer Mario Lecano picked up the jawbone after running into the water to retrieve his daughter, who was not wearing a life jacket at the time. "As soon as I grabbed her, I saw down by her legs that there was, what appears to be, some bones and some teeth," Lecano told television station KVVU-TV.
Shortly after the initial discovery, additional bones including several ribs were spotted along the rapidly receding shoreline. The Las Vegas Metropolitan Police Department confirmed in a statement that the bones belonged to a "non-criminal, dead body" and were taken for forensic examination.
Authorities stated it was unclear how long the body had been submerged in the reservoir or whether the individual was the victim of a crime. The Clark County Coroner's Office is also involved in examining and identifying the remains.
Visitors to the lake expressed concern over the shrinking shoreline and the recurring discovery of human skeletons. "We noticed that it is very low. The water looks very low compared to where it should be. As the water goes down, the skeletons come up," beachgoer Noel De Leon told 8 News Now.
Previous human remains discovered as lake recedes
The discovery on August 16 is the latest in a series of similar finds exposed by severe drought and heavy water usage in recent years. In 2022 alone, authorities and visitors uncovered four separate incidents involving human remains around Lake Mead.
In October 2022, National Park Service rangers pulled a human skeleton from Callville Bay, located about 15 miles away from Boulder Beach. Forensic examiners later determined the bones belonged to drowning victim Donald Smith, who disappeared in Lake Mead in April 1974, and ruled the death an accident.
Earlier that year, in May 2022, paddleboarders in Callville Bay discovered the skeletal remains of 42-year-old Thomas Erndt, another drowning victim who died two decades before his body was recovered.
A more disturbing case occurred on May 1, 2022, when a victim was discovered inside a rusted metal barrel in Hemenway Harbor. Detectives with the Las Vegas Metropolitan Police Department established that the man had been shot to death and placed in the barrel, believing the homicide occurred in the mid-1970s or early 1980s. The victim has never been identified.
Speaking to television station KSNV after the barrel was found, Geoff Schumacher, vice president of the Mob Museum in Las Vegas, noted potential ties to organized crime history. "When you look at the way the person was killed, and when you think about how the body was disposed of, all of these things kind of tie together with some kind of a mob-related event," Schumacher said.
In August 2022, another set of human remains was recovered from the lake and identified as Las Vegas resident Claude Russell Pensinger. Pensinger had disappeared during a fishing trip on July 14, 1998, though examiners could not determine his cause of death.
Reservoir drops to historic low elevation
As of Wednesday, the surface elevation of Lake Mead stood at just under 1,040 feet above sea level, leaving the reservoir around 180 feet below its full capacity of 1,220 feet. The last time the lake approached full capacity was around the year 2000.
Water levels at the reservoir have been dropping steadily over the past three decades due to heavy regional usage across the Southwest, severe drought, and a lack of snowpack melt at its source in the Rocky Mountains. The drop has exposed large portions of surrounding mountains and shorelines that had been submerged since the lake was created in the 1930s.
Formed by the construction of the Hoover Dam on the Colorado River between Nevada and Arizona, Lake Mead is the largest reservoir in the United States. For decades, it has supplied drinking water, household plumbing, and hydroelectric power to millions of residents in the Southwest.
Threat to Hoover Dam hydroelectric power
The severe decline in water levels has also sparked urgent warnings regarding hydroelectric power production. The US Bureau of Reclamation, which manages federal dams and reservoirs, warned that Lake Mead's current elevation sits just five feet above the threshold where older turbines at the Hoover Dam hydroelectric facility will be forced to shut down to prevent damage.
The hydroelectric facility at Hoover Dam generates approximately four billion kilowatt-hours of power each year, supplying electricity to more than one million people across Arizona, California, and Nevada.
Officials warned that if severe drought drops water levels below 950 feet, the entire facility, including its newer turbines, will be forced to cease operations. The water shortage has been particularly acute near the source of the Colorado River in the Rocky Mountains, where unusually low snowpack totals have produced less meltwater to replenish the shrinking lake.
