The Story
Visitors and locals tell of a long, dark, dinosaur-like creature that lives in Lake Tahoe, nicknamed Tahoe Tessie after Scotland’s Nessie. Moonshine Ink (a Tahoe news outlet) reports that stories of a lake monster at Tahoe go back about 100 years and that sightings have been reported since the early 20th century [2]. The Tahoe Maritime Center’s curator and a Kings Beach author named in the article keep the character alive in Tahoe art and children’s books [2]. In April 2005 the Tahoe Daily Tribune reported a fresh sighting about 100 yards off Tahoe Park Beach by two visitors [3].
What Is Actually True
- The name “Tahoe Tessie” is modern. The author who created the modern character, Bob McCormick of Kings Beach, told Moonshine Ink he coined the name on a 1975 sea-kayaking trip, published his book in 1984, and says it has sold about 110,000 copies [2].
- Moonshine Ink says it is “often stated” that Tessie has roots in Washoe culture, then says the Water Babies near Cave Rock and the Ong legend are “better documented” than any Washoe Tessie [2]. This site does not tell Washoe stories because the Washoe Tribe’s own public site was not read (see unverified file).
- The Associated Press (via PBS NewsHour) described “tribal tales” of a Loch Ness-like creature beneath Cave Rock that was later dubbed Tahoe Tessie [4]. The AP does not name a tribe or a source for those tales [4].
- UC Davis limnologist Charles Goldman, quoted in the Tahoe Daily Tribune, said no one has ever seen a Tessie head or tail, only dark shapes in the water; he pointed to waves and thrown-rock splashes as look-alikes, and other explanations offered include a large sturgeon [3][2].
- Scuba divers and volunteers working with Clean Up the Lake removed about 25,000 pounds of underwater litter across 189 dives (May 2021 to May 2022, dives to 25 feet) and found no sign of Tessie; Desert Research Institute scientists analyzed the finds [4].
- Context: Lake Tahoe’s deepest recorded depth is 1,645 feet [5].
Still Unconfirmed
Any earlier written account than the 20th century; any Washoe origin for Tessie itself; any photograph of a creature.
Frequently Asked Questions
Has anyone proved Tahoe Tessie exists?
No. The Tahoe Daily Tribune quotes UC Davis scientist Charles Goldman saying no one has seen a head or tail, only dark shapes [3], and a 2021-22 diving cleanup found no sign of her [4].
Where does the name Tahoe Tessie come from?
Author Bob McCormick told Moonshine Ink he coined it on a 1975 kayaking trip; his book came out in 1984 [2]. Tessie is a nod to Scotland’s Nessie [2].
Is Tessie a Washoe legend?
Some people say so, but Moonshine Ink calls the Water Babies and Ong the better-documented Washoe stories, and says the Tessie link is only “often stated” [2]. For Washoe history, go to the Washoe Tribe’s own site.
