Waterdog Lake, Belmont: Haunted History & Our Investigation

Waterdog Lake in Belmont, California, has always been more than another supposedly haunted location to me. I grew up hearing stories about its wooded trails, the lake, and a terrible crime. On October 2, 1984, I was at soccer practice at the middle school when 12-year-old Lance Turner disappeared and was murdered nearby. That personal connection is why the story has stayed with me—and why I eventually returned to the area to investigate its paranormal reputation for LiveSciFi.

When people ask whether Waterdog Lake is haunted, I think it is important to start with what we can actually document. The homicide was real. The court record is extensive. Reports of ghosts, strange sounds, and tunnels associated with occult activity are a different kind of claim. In this article, I want to explain the history, the crime that changed the community, what I experienced during my ghost hunt, and what remains unproven.

Where Is Waterdog Lake, and Why Is It Considered Haunted?

Waterdog Lake sits within a network of wooded hills and trails in Belmont, San Mateo County, California. The City of Belmont describes Waterdog Lake Open Space as a public trail area, with access points at Lyall Way, Carlmont Drive, and Hallmark Drive/Lake Road. The city says the lake takes its name from a local salamander and lists the park’s opening hours as sunrise to sunset. See Belmont’s official park information.

Growing up nearby, I heard stories that the lake was haunted by the spirit of a boy who had drowned there. I also heard rumors about old tunnels and ritual activity. The atmosphere makes those stories easy to imagine: dense brush, changes in elevation, and paths that can feel isolated from the city. But atmosphere isn’t evidence. I have not found reliable documentation that establishes the alleged haunting or ritual activity as fact.

The History of Waterdog Lake and the Ralston Estate

Long before Waterdog Lake became part of local ghost stories, the reservoir was connected to Belmont’s early development. The original LiveSciFi article described its relationship to the estate of William C. Ralston and the historic waterworks that helped serve the area. Historical material preserved by the local Belmont Historical Society also describes Chinese laborers constructing a dam for Ralston and a channel carrying water for irrigation. Read the historical newspaper clipping archived by the Belmont Historical Society.

That engineering history may also help explain why underground water infrastructure became part of the lake’s folklore. It’s tempting to turn every old tunnel into a paranormal mystery. I don’t think we need to do that. The documented history is interesting on its own; stories about rituals inside the passages should be treated as local legend unless convincing evidence emerges.

The Waterdog Lake Murder: What Happened to Lance Turner in 1984?

On October 2, 1984, 12-year-old Lance Turner was expected at soccer practice behind Ralston Intermediate School in Belmont. According to the California Supreme Court’s account in People v. Dunkle, Timothy O’Brien drove Lance and his own sons to the fields. Later, when practice ended, the adults realized Lance had not attended his scheduled practice. Other boys reported seeing him head toward Waterdog Lake, approximately three-eighths of a mile from the soccer field.

My Personal Connection to the Day Lance Disappeared

I was at soccer practice at the middle school that day. That’s the detail that makes this more than a story I researched years later. While we were there for an ordinary afternoon of soccer, a child from the same community was disappearing into an area many of us knew. Lance did not come back from what should have been an ordinary afternoon. The court record describes the attack near the lake; it does not establish a separate kidnapping before the murder.

I want to be careful not to suggest that I witnessed the attack or know what Lance experienced. My connection is that I was practicing at that school on the same day. When I later learned the details, the location and the timeline became impossible for me to separate from my own memories of growing up in Belmont.

The Search Near Waterdog Lake

By approximately 7 p.m., Lance’s mother, Margaret Turner, reported him missing. A search was already underway. The court recounts that William Russell, another parent connected to the soccer practice, joined the effort. At about 8:20 p.m., he noticed Lance’s feet among the bushes in a gully near a path leading toward the lake. Lance’s body was discovered concealed in the brush.

The medical evidence was devastating: the pathologist testified that Lance died from blood loss caused by multiple stab wounds, including fatal injuries to the heart. There were also defensive injuries. I include those facts because they are central to the documented history, not because the details should be turned into entertainment. Lance was a child, and his family and community lived with the consequences.

Witnesses, the Suspect, and the Confession

Students from Ralston Intermediate School later testified that they had encountered a young man near the lake that afternoon. He introduced himself as Jon, spoke with them, and was drinking beer. Their descriptions contributed to a police composite. The court noted that these witnesses were not asked to identify the defendant in the courtroom, a distinction worth preserving when retelling the case.

The man ultimately convicted was Jon Scott Dunkle. During questioning in December 1984, Dunkle denied being at Waterdog Lake on the day of the murder. Investigators continued their work, including an undercover operation. In 1986, while in prison on an unrelated conviction, Dunkle gave accounts of the killings to a fellow inmate and later spoke with FBI agents.

In his account of the Turner killing, Dunkle said he had been drinking in the area, had encountered three girls, and then approached a boy jogging near the lake. He described attacking Lance with a knife and hiding his body in the brush. These statements were part of the evidence described by the court; they are not my reconstruction of what someone saw that afternoon.

The Other Murder Linked to the Case: John Davies

The investigation also brought answers in a separate tragedy. John Davies, 15, disappeared from Belmont in November 1981. According to the Supreme Court’s opinion, Dunkle was close to the Davies family. Years after John disappeared, Dunkle’s statements directed investigators to evidence connected to John’s death near Edgewood Park. The jury convicted Dunkle of the first-degree murders of both John Davies and Lance Turner.

That is an important part of the Waterdog Lake story. Lance’s murder was not merely an isolated piece of spooky local folklore; it became part of a major criminal case involving multiple victims. The California Supreme Court affirmed Dunkle’s convictions and death judgment in 2005. That is the historical appellate ruling, not a claim about his present custody or sentence status.

Is Waterdog Lake Haunted? The Stories Behind the Legend

For decades, people have repeated stories about a drowned boy, unusual sounds, and a haunting connected to Waterdog Lake. Those accounts are part of the area’s local lore, but they do not prove that a spirit is present. A listing on Haunted Places shows how residents and visitors continue to exchange different—and sometimes conflicting—memories about the site. A later regional feature also mentioned tunnel legends and supposed ritual activity, without establishing them as fact.

One thing I will not do is claim that Jon Dunkle participated in Satanic rituals or that the murders were connected to the tunnels. I found no credible evidence for that claim in the court record. There is already enough real tragedy here without inventing a supernatural motive.

Watch My LiveSciFi Ghost Hunt at Waterdog Lake

I eventually returned to the area for a LiveSciFi live-streamed ghost hunt. In the original article, I described capturing several sounds I considered possible electronic voice phenomena (EVPs) and hearing what seemed to be a disembodied voice. The recording is part of my experience at the location, but listeners should make their own judgments. Environmental sound, recording artifacts, and expectation can all shape what we think we’re hearing.

Here is the footage from my Waterdog Lake ghost hunt. Watch it and listen for yourself rather than relying on my interpretation alone.

Is It True? Waterdog Lake’s History, Tragedy and My Ghost Hunt

My connection to Waterdog Lake is personal: I grew up around the area and remember being at soccer practice at the middle school on the day the community learned of a child’s disappearance. The murder documented in the court record is a human tragedy that deserves to be told carefully. Years later, I returned to explore the haunted reputation of the lake and surrounding tunnel and recorded what I encountered during my own LiveSciFi ghost hunts.

The lake’s ghost stories, ritual rumors and tunnel legends are part of its modern folklore; they are not a reason to mischaracterize a victim or the crime. The historical sources below establish the people and events, while the linked investigation videos let visitors hear the sounds, see the setting and follow my reactions as they occurred.

My assessment: Waterdog Lake has documented history, a real tragedy and a longstanding paranormal reputation. The recordings let viewers examine what I heard and how I interpreted it. They do not establish that a ghost, a portal or the murder victims caused the reported sounds.

How I Separate the Crime, the History, and the Paranormal Claims

After years of investigating reportedly haunted locations, I have learned that a gripping story and verifiable evidence are not the same thing. At Waterdog Lake, the 1984 murder, the victims’ identities, the search, and the conviction have a documentary record. The drowning legend, ritual stories, and reports of ghostly voices require a different standard of scrutiny.

As an investigator, I can tell you what I heard, what I recorded, and why I chose to visit. I can’t tell you that a recording proves a spirit was there. I also can’t establish that the deceased are responsible for noises or sensations at the park. The victims deserve more than to become props in a ghost story.

For me, Waterdog Lake remains one of the most personal locations I have ever covered. I know the school, the landscape, and the sense of an ordinary community changed by something terrible. That personal history is part of why I wanted to document the lake—and why I think its story needs to be told carefully.
