LAS VEGAS — Another object has been discovered as the waters in Lake Mead continue to shrink.

The Associated Press reported that a World War II-era landing craft appeared last week after it previously sat 185 feet below the surface.

The news outlet reported that it now sits sideways a mile from Lake Mead Marina and Hemingway Harbor.

Dive tours company Las Vegas Scuba said the boat surveyed the Colorado River decades ago but was sold to the marina and then sunk, the AP reported.

The Higgins landing craft is the latest discovery as water levels dwindle.

Two sets of human remains were found in the lake two months in the same week, Scripps sister station KTNV reported.

The AP reported that experts say water levels are dropping due to climate change and drought.

CLARK COUNTY, Nev. —

After a diver found what appeared to be a human bone in Lake Mead, the park searched the area and uncovered more human remains, the National Park Service confirmed Wednesday.

The diver, who is a private business operator at the Lake Mead National Recreation Area, found the bone in the Callville Bay area of Lake Mead on Oct. 17, according to park spokesperson Stefani Dawn. The next day, a park dive team searched the area and "confirmed the finding of human skeletal remains," Dawn said.

The finding marks at least the sixth time human remains have been uncovered at the lake this year, many due to the lake's dropping water levels from prolonged drought. Some of the discoveries have only been partial sets, so it is unclear how many people's remains have been found.

The Clark County Coroner's Office, which is handling the remains found this year, previously told CNN that medical examiners were still working to determine whether the partial sets were from separate people.

It is unclear if the bone found on Oct. 17 and the remains found on Oct. 18 belong to the same person.

"At this time, no foul play is suspected," Dawn said. "The Clark County coroner's office has been contacted to confirm the identity of the deceased."

As a decades-long drought parches the American West, Lake Mead's water supply has suffered, causing the man made reservoir's shorelines to dramatically recede and reveal some remains that were once submerged.

The first discovery came on May 1, when a set of remains was found in a corroded barrel with an obvious gunshot wound, Lt. Jason Johansson of the Las Vegas Metropolitan Police homicide unit told CNN in August.

Investigators quickly determined the body belongs to a homicide victim who died in the mid-'70s to early '80s. Medical examiners have been trying to identify the person through DNA analysis, though the advanced decomposition of the remains makes identification challenging, according to Clark County Coroner Melanie Rouse.

Within a week of the homicide victim's remains being found, another set was discovered in the Callville Bay area. Medical examiners have since identified the remains as those of 42-year-old Thomas Erndt, who is believed to have drowned in the lake in 2002.

Four more discoveries were made in the months that followed, including at least two sets of partial remains in the park's popular Boulder Beach area.

Dropping water levels have also uncovered relics including sunken boats, a World War II-era landing craft and ancient volcanic rock.

CASA GRANDE, Ariz. — Nancy Caywood knows the value of holding on to what’s important to you. Her family’s farm is on its fifth generation.

“This is my grandad. He’s out working our family farm in the 1940s right here. He purchased the farm in 1930,” she said.

For 91 years, Nancy’s family has been farming land in Casa Grande, Arizona, about an hour south of Phoenix. So she’s seen some dry weather in her day.

“All of the west is in a serious drought,” said Caywood, “The lakes are decreasing in level, and they’ve all got the bathtub ring, and they’re very, very low right now, and so we just entered what we call tier one of water usage which means that agriculture is going to be cut back.”

The Bureau of Reclamation declared a water shortage in the Lower Colorado River Basin and announced level one restrictions, the first-ever.

"The basin is experiencing its 22nd year of drought, and earlier this summer, the reservoirs hit their lowest levels since they were originally filled," said Tonya Trujillo, the Asst. Secretary for Water and Science.

That means Arizona will face the largest cuts at an 18% reduction. Nevada will see a 7% reduction and Mexico 5%. Those numbers may not sound like a lot to the average person, but to farmers, every drop counts.

“In all honesty, we probably had about, trying to think, probably about 25 acres on this farm this year just because we didn’t have the water," said Paco Ollerton.

His farm is just down the road from Nancy’s. Uncertainty is starting to sink in for Paco for his farm and others.

“My guys are going to have less, my equipment dealer is going to have, you know people are being conservative about buying equipment, it’s going to affect all the suppliers and the inputs,” said Ollerton.

Caywood worries about her son Travis, who runs the farm now.

“Now I’ve just watched this just wear him down, and it’s sad as a parent to see this because I don’t think my grandfather ever experienced this level of drought. But this has been a year, after year, after year, it’s been going on, and to watch this just wear Travis down hurts, it just hurts. And you just want to say it’s going to be ok, but we don’t know,” said Caywood.

Telling the people we love that everything will be OK, you don’t have to be a farmer to know that feeling.

But it might take a farmer to find that glass half full optimism in the middle of a drought. Nancy’s got that too.

“I look out here, and I know that the alfalfa is here, and we can grow it. We just need water, right? And so you just have to look with optimism that we’re going to get water,” she said.
