Tourilli River
The Rivière Tourilli is a tributary of the Sainte-Anne River flowing in the unorganized territory of Lac-Croche and the municipality of Saint-Gabriel-de-Valcartier, in the La Jacques-Cartier Regional County Municipality, in the administrative region of Capitale-Nationale, at Quebec, in Canada. The upper part of this watercourse crosses the southwest part of the Laurentides Wildlife Reserve. The lower part of the Tourilli river is mainly served by the forest road R0354 (north–south direction) for the needs of forestry and recreational tourism activities. The upper part is served by the forest road R0355  and the R300. Forestry is the main economic activity in the sector; recreotourism activities, second. The surface of the Tourilli River (except the rapids zones) is generally frozen from the beginning of December to the end of March, but the safe circulation on the ice is generally made from the end of December to the beginning of March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April. Geography. The Tourilli River rises at the mouth of Tourilli Lake (length: ; altitude ) in the unorganized territory of Lac-Croche. This  lake between the mountains is fed by the outlet of Lake Vermuy, Lake Josselin and small mountain streams. A mountain peak culminates at south of the lake and another at to the southwest. The mouth of Lac Tourilli is located southwest of Petit lac Jacques-Cartier, west of the course of the Jacques-Cartier River, at north of the confluence of the Tourilli and Sainte-Anne rivers, at north-west of the village center of Saint-Gabriel-de-Valcartier and north of the confluence of the Sainte-Anne River with the St. Lawrence River. From the mouth of Lac Tourilli , the Tourilli river flows over entirely in the forest zone with a drop of , according to the following segments: Upper course of the river (segment of ) Intermediate river course (segment of ) Lower river course (segment of ) The Tourilli river flows in a bend on the east bank of the Sainte-Anne river. This confluence is located west of the course of the Jacques-Cartier River, north of the center of the village of Saint-Raymond and north of the confluence of the Sainte-Anne with the Saint Lawrence river. From this confluence, the current descends on generally south and southwest  following the course of the Sainte-Anne river, to the northwest bank of the Saint Lawrence river. Toponymy. In a mountainous landscape, the profile of the river and its valley sometimes appears in cascades, sometimes in almost vertical walls. This wooded area was long renowned for the richness of its forest species and game, as evidenced by the surveyor John Neilson in 1888. This toponymic designation, of Aboriginal origin, appears for the first time in a text by the surveyor John Adams in 1829, in the form "Atourile". Two translations are known for this word: "the executioner" and "agitated water ; this latter meaning, linked to the language wendate, seems to have been imposed. The region having been frequented by several Aboriginal nations in the last century, it often happened that several names or meanings were used for the same entity. In addition, on a survey plan dating back to 1854, the Tourille river shape can be noted. The toponym Rivière Tourilli" was formalized on December 5, 1968, at the Bank of Place Names of the Commission de toponymie du Québec.
