Lake Mead's Historic Lows Uncover Sixth Set of Human Remains

Lake Mead’s dropping water levels have revealed a sixth set of human remains since 2022, discovered on August 16 at Boulder Beach within the Lake Mead National Recreation Area. The latest findings include a jawbone with teeth and dental fillings, along with some rib bones. A woman, a man, and his daughter found the remains on the Nevada side of the reservoir.

National Park rangers and Las Vegas police responded to the scene and recovered the bones. The identity of the victim and the cause of death are not currently known. The Las Vegas Metropolitan Police Department stated that "A non-criminal, dead body report was taken for the remains."

These grim discoveries are occurring as Lake Mead continues to fall to record low elevations. The reservoir, an artificial body of water upstream of the Hoover Dam on the Colorado River, straddles Clark County, Nevada, and Mohave County, Arizona. The U.S. Drought Monitor reported moderate drought conditions across much of the Clark County region as of August 18.

Lake Mead's water level has declined by more than 175 feet since the year 2000, according to data from the Bureau of Reclamation. This represents a net water loss of nearly 6 trillion gallons. Researchers indicate that rising temperatures, attributed to climate change, are intensifying drought conditions and reducing runoff across the broader Colorado River Basin. The current surface level of Lake Mead is now close to what it was in March 1937, when the lake was in the process of filling behind the recently completed Hoover Dam.

Due to this substantial water loss and the multiple findings on the drying lake bed, Lake Mead now offers both a glimpse into American West history and a look at the future impacts of climate change. The Guardian reported that some experts anticipate further discoveries, partly because Lake Mead is located approximately 20 miles from Las Vegas, a city with a known history tied to organized crime.

The earliest of the recent string of discoveries occurred on May 1, 2022, when boaters found a body encased in a rusting metal barrel near the Hemenway Harbor boat launch. Police investigators stated that the area where the barrel was found would have been submerged about 100 feet underwater and several hundred feet from shore in the 1980s. This specific case is the only one among the recent findings being investigated as a homicide. Based on the clothing and shoes found with the remains, Las Vegas police believe the victim was a man who died from a gunshot wound in the mid-1970s or early 1980s. His identity has not yet been established.

Just days later, on May 7, 2022, paddleboarders discovered skeletal remains in the Callville Bay area. These were later identified by the Clark County coroner's office as Thomas Erndt, a 42-year-old Las Vegas resident. Forensic analysis, including a DNA sample and X-rays, aided in the identification. News reports from the time indicated Erndt was reported missing and presumed to have drowned after jumping off a boat on August 2, 2002. An official cause of death for Erndt has not been determined.

Further partial human remains were found at Swim Beach near Boulder Beach on July 25, 2022. Additional fragments discovered on August 6 and August 16 were later linked to the initial finding and identified as belonging to Claude Russell Pensinger, who had disappeared in 1998. The National Park Service reported that a third set of skeletal remains, also later identified as Pensinger, was discovered at Swim Beach on August 15, 2022. These multiple fragments attributed to Pensinger were recovered by park rangers and the Las Vegas Metropolitan Police dive team.

Beyond human remains, Lake Mead’s receding waters have also brought other significant historical artifacts back into view. Among these is a World War II-era Higgins landing craft, which had been modified for lake service and used to survey the Colorado River. This plywood boat, still wrapped in armor plating with its engine removed, is now visible less than a mile from Lake Mead Marina and Hemenway Harbor. The National Park Service has not confirmed whether the boat sank by accident or was intentionally submerged. Higgins boats were instrumental in landing troops and equipment during invasions, including the D-Day invasion of Normandy in 1944, with over 20,000 different configurations built. National park staff had been conducting scuba dives on this particular boat since 2006.

Another historical site re-emerging from Lake Mead is the town of St. Thomas, Nevada. Founded in 1865, the town is located in the northern part of the park near the Overton Arm along the Muddy River. Residents began evacuating St. Thomas in 1935 after the completion of the Hoover Dam, and the town became submerged by 1938 as Lake Mead filled. While water levels fluctuated over the decades, leading to reunions for former residents and family members in 1945, 1963, and 2012, much of St. Thomas has been above water since 2004. At Lake Mead's highest level in 1983, the town was 60 feet underwater. Today, visitors can walk through the remaining structures of the once-submerged community.

Lake Mead holds the distinction of having the largest storage capacity of any reservoir in the United States. However, decades of increasing water demand coupled with persistent drought conditions in the American West have led to a continuous decline in its water levels. NASA observations indicate that Lake Mead's shorelines are now lower than at any point since the 1930s. While approximately 10% of Lake Mead's water originates directly from precipitation, the National Oceanic and Atmospheric Administration states that the majority of the lake's water comes from melting snow in the western Rocky Mountains.
