Vermont DOT’s routine lake bed survey hit a snag — specifically, a snag that appears to breathe and turn around.

On the morning of September 4th, aboard a contracted survey vessel approximately 340 meters off the Burlington shoreline, sonar technician Marcus Fleury was doing what sonar technicians do: watching a screen, drinking bad coffee, and expecting absolutely nothing interesting to happen. What he got instead was a bathymetric return measuring roughly 9.2 meters in length, exhibiting what the official amended survey log now diplomatically describes as ‘anomalous mass displacement consistent with internal locomotion.’ What Fleury’s own handwritten field notes describe, rather more candidly, is: ‘That is not a log. Logs do not turn.’

The survey in question was commissioned by the Vermont Department of Transportation as part of a standard hydrological assessment ahead of planned infrastructure work near the Champlain Bridge corridor. It was not, to be clear, a cryptid hunt. It was not funded by anyone wearing a Champ t-shirt. It was the kind of survey that produces spreadsheets and boring elevation maps and zero headlines — until it didn’t. WTC News obtained the original unredacted field logs alongside the amended version submitted three days later, and I am here to tell you that somebody had a very busy editing weekend.

What the Data Says, and What Someone Tried to Make It Stop Saying

The original sonar return, captured at 9:14 AM local time, shows a solid, high-density mass resting near the lakebed at a depth of 28 meters. Standard stuff. What happens over the following 11 minutes of continuous recording is decidedly less standard. The object — and I am using that word loosely and somewhat nervously — shifts position twice, rises approximately 4 meters toward the surface, and at one point produces what the sonar visualization software flagged as a ‘secondary oscillating appendage signature.’ The amended version of the log replaces this entire sequence with the notation: ‘Signal degradation. Possible debris interference. Data excluded per QA protocol.’ There is no QA protocol cited. I checked.

I have done thirty-one lake and coastal surveys in my career. I know what debris looks like. I know what fish look like. I know what thermocline artifacts look like. I do not know what that looked like, and that is precisely why I wrote it down exactly as I saw it.

The contracted marine geologist on the project, Dr. Yolanda Prescott of Meridian Bathymetric Solutions, reviewed the raw sonar imagery as part of her independent deliverables. Her official notes — which WTC News also obtained, because we have sources and we are not sorry — include the phrase ‘biologically inadvisable,’ which she used to describe the object’s apparent dimensions relative to known Lake Champlain fauna. When reached for comment, Dr. Prescott clarified that ‘biologically inadvisable’ is, in her professional vocabulary, a term reserved for things that ‘probably shouldn’t exist based on the available food chain data, but appear to anyway.’ She then asked how we got her notes. We thanked her for her time.

I chose those words carefully. ‘Biologically inadvisable’ means the ecosystem math doesn’t support it. It does not mean it isn’t there. It means it’s there and the ecosystem is simply going to have to deal with that.

The Amendment Nobody’s Talking About (Except Us, Right Now)

The Vermont Department of Transportation, when contacted by WTC News, issued a statement confirming that the survey had been completed ‘within standard parameters’ and that ‘all data anomalies were reviewed and resolved through established quality assurance procedures.’ The DOT did not respond to follow-up questions about which QA procedure specifically covers 9-meter objects with appendage signatures, or who authorized the amended log submission, or whether the infrastructure project near the Champlain Bridge has since been quietly scoped back. That last one we noticed on our own, by comparing the original project specification documents to the revised scope published on October 1st, which now notably excludes any work in the 28-to-35-meter depth zone directly east of the original survey grid. Draw your own conclusions. I have already drawn mine and laminated them.

Look, I’ve been covering this beat for eleven years. I’ve sat through grainy footage, I’ve interviewed people who’ve had long, eventful conversations with Bigfoot, I’ve reported on a mothman sighting that turned out to be a very determined hang glider. I know the difference between a story and a story. This is a story. Seven people on a boat watched a sonar screen show them something that made a trained geologist reach for the word ‘inadvisable.’ One of those people wrote it down in real time. Then, seventy-two hours later, someone decided the official record should say something different. Marcus Fleury still has his original notes. Dr. Prescott still has hers. And whatever was at 28 meters on the morning of September 4th is presumably still at 28 meters, doing whatever it does, entirely unbothered by our documentation protocols. This is Hal Ridgeway for WTC News. Stay curious. Stay dry. Maybe stay off the lake for a bit.
