More human remains were found in Lake Mead on Saturday – the fourth set of remains recovered since May – as a scorching drought continues to cause water levels to drop. Visitors discovered the remains around 11:15 am. at Swim Beach at Lake Mead National Recreation Area in Nevada and called rangers, the National Park Service (NPS) said in a statement. Rangers set up a perimeter to recover the remains with the help of the Las Vegas Metropolitan Police Department’s dive team. The Clark County Medical Examiner has been contacted to determine the cause of death, officials said.

The last body discovered in Lake Mead was on July 25, when visitors called park rangers after finding the remains partially encased in mud at the waterline of the swimming area along the shore north of the Hemenway Harbor Marina. The medical examiner at the time of the discovery of the third body said her office was continuing to work to identify a man whose body was found May 1 in a rusty barrel in the Hemenway Harbor area and a man whose bones were found on May 7.

NASA released images of Nevada’s Lake Mead last month showing the rapid decline of the lake’s water since 2000. The reservoir last reached capacity in the summer of 1999, according to NASA.
