The Waterspirit of Rock River
retold by Richard L. Dieterle
A great Waterspirit which inhabited the Rock River (Werošanagra) patrolled it from its source to the river's terminus in Lake Koshkonong. It seized and swallowed whole deer that got too near the lake. It also ate humans. It especially liked to ambush people at fords along the river, but people in canoes were no safer: it would capsize boats with a slap of its tail, then devour the unfortunate victims as they struggled in the water. On rare occasions people saw the Waterspirit but most of the time the only indication of its presence was the boiling and churning of the river's waters. Its dens were in the deepest waters where it would carry off its victims and eat them in solitude. In the spring it would often break up the ice and cast it towards the shore.
It could often be placated by tobacco and red feathers or other such offerings. 
Commentary. In this connection, see the remarks of Capt. Jonathan Carver on an animal killed by the Hočągara at Lake Winnebago prior to 1768. The Hočąk name of the river is said to be Werošanagra, and to mean "Rock River."  This is not likely, although the ending seems to be [nį]šąnągra, "the river." However, D. M. Brown gives the name as Eneenneshunnuck [Ini-nįšąnąk], which translates literally as "Rock River."
