Storsjöodjuret

The full file

Storsjön is a large lake in Jämtland, with Östersund on its shore and the island of Frösön opposite. The animal said to live in it has a folklore older than Nessie's, a nineteenth-century press frenzy, a company formed to catch it, and, unusually, a file of legal papers: from 1986 to 2005 it was a protected species by order of the county. None of this produced an animal. The paperwork is what makes it a case.

What was reported

The oldest layer is folklore about a lake serpent bound in the water by the Frösö runestone, the eleventh-century stone near the bridge to Frösön whose carving includes a serpent. In the legend the binding was done by the sorcerer Kettil Runske. The date usually given for the first written account is 1635, from a manuscript attributed to a local clergyman whose name is given in more than one form; none of the sources cited here gives that date or names the author, so it is treated here as unverified. The human ecologist Sanna Händén-Svensson puts the link between stone and serpent at least as early as the first part of the seventeenth century. In that tradition the creature was a rå, a spirit ruling a place, not a zoological claim.

The zoological claim came in the late nineteenth century. Witnesses from farmers to members of parliament described something long and dark rolling in the water, often likened to an upturned boat. A search of digitised Swedish newspapers by Henrik Ullstad counted 217 items in 1898, 219 in 1899 and 224 in 1900; one later account cites these figures as items about the creature and another as reported sightings, and they are better read as press attention than as a count of witnesses. In 1894 a company was formed in Östersund to catch the animal. Contemporary newspapers name Maria Helin, the steamboat captain Anders Dedering, Vilhelm Sköld and a merchant named Dahlin. They built a raft on piles lit by electric lamps, contracted a harpooner from Norway, and had a larger harpoon forged locally when the one ordered proved too small.

The evidence and where it is

There is no specimen, no tissue and no instrument record. What survives is paper and ironwork. The reports gathered by the zoologist Peter Olsson for his 1899 booklet Storsjöodjuret are held in the Zetterström collection at Östersund city library. Jamtli, the county museum, holds a large archive of accounts and cuttings, which it puts at a little over 260 sightings, and displays a giant pair of baited shears used as a trap at the end of the 1800s, attributed to the 1894 company. The county's own files on the protection run to nearly 200 pages, from 1962 to 2008.

What investigators concluded

Olsson argued for an unknown animal, in one account a giant seal. The Uppsala University zoologist Einar Lönnberg went to Östersund for Aftonbladet in December 1898 and reported in that paper over the following weeks. In 1900 the antiquarian Carl Wibling proposed a beaver family, and a lieutenant, Otto von Mentzer, was sent to look; he found neither beaver nor monster. No new species was described, and zoologists withdrew.

The modern conclusion is legal. On 22 January 1986, on an application from the Östersund tourist office, the County Administrative Board used §14 of the Nature Conservation Act to forbid killing, harming or capturing the animal in Storsjön, and to protect its eggs, roe or nest. In November 2002 a private applicant asked for an exemption to collect eggs. The Board refused; on 11 July 2003 the environmental court in Östersund dismissed his appeal because the request concerned "a scientifically unverified animal species". The Parliamentary Ombudsman, Nils-Olof Berggren, took the matter up after inspecting the court in 2004, and in a decision of 9 November 2005 agreed with the court that the regulation could not be applied and expected the Board to revoke it. The Board did so, calling its own 1986 decision "an obviously incorrect application of the law". Händén-Svensson and Hanna Jansson cite a county file dated 14 November 2005; some later accounts place the revocation in early 2006.

The leading conventional explanation

The standard account is misidentification shaped by expectation: waves and boat wakes on a large, wind-exposed lake, swimming animals, floating timber, seen briefly and at distance by people who already knew the serpent story. Its strengths are that the reports cluster with newspaper coverage and that descriptions vary widely in colour, size and form. Its weakness is that it has never been tested against individual reports; Wibling's beaver idea is the only specific candidate that was investigated in the field, and it failed.

What remains unexplained or disputed

The 1635 text and its author's name need checking against the manuscript itself. The royal role is disputed: press reports since 2008 say King Oscar II helped fund the 1894 hunt, while Händén-Svensson, working from contemporary newspapers, doubts the oft-cited claims of the monarch's money for the company. The revocation date differs between accounts. Why the Board acted is also read two ways. Its file presents an ordinary conservation case, but Jansson and Händén-Svensson note that the request came from the tourist office in the year of Östersund's bicentenary, and argue that the order was a "communicative act" in a "playful legal space" rather than an attempt to protect a known animal.
