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 ) east, then north, in particular by crossing Lake Martel (length: ; altitude: ), to its mouth; north-west, branching north, then east, in particular crossing Lac Trigone (length: ; altitude: ), to its mouth; to the east, in particular by crossing Lac des Laiches (length: ; altitude: ), up to at its mouth. Note: Lac des Laiches receives on the north side the discharge of a set of lakes (Inerte, Plissé, Hudon and Petit lac Hudon); to the east, by forming a hook towards the south to pick up the outlet (coming from the west) of Juneau Lake, before crossing Gregory Lake (length: ; altitude: ), to its mouth. Note: Lac Gregory receives on the north side the outlet of Lac des Doradilles, the outlet of a set of lakes including Hunau, Crochetière and Pleurotes, as well as the outlet of lakes Fruze, Chesnay, Godman, Etheleen, Petit lac Etheleen and Piedmont; Intermediate river course (segment of ) towards the south-east by first cutting the forest road R0300 which passes in the east–west direction on an istme with a length of before to cross a small lake (length: ; altitude: ),
