The lower part of this small valley is served by Chemin Royale (route 368) which runs along the southeast shore of Île d'Orléans. Besides a small forest area crossed in the upper part, agriculture constitutes the main economic activity of this small valley.
The surface of the Dauphine River is generally frozen from the beginning of December until the end of March; however, safe circulation on the ice is generally done from mid-December to mid-March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
Geography
The Savannah river originates from a small agricultural lake (altitude: 76 metres (249 ft)), located between two hills, in Saint-François-de-l'Île-d'Orléans. This source is located 3.3 kilometres (2.1 mi) south-west of the village center of Saint-François-de-l'Île-d'Orléans, 3.4 kilometres (2.1 mi) south-west east of chenal de l'Île d'Orléans and 2.1 kilometres (1.3 mi) west of the shore of the Saint Lawrence River (Chenal des Grands Voiliers).
From this source, the course of the Savane river descends on 3.2 kilometres (2.0 mi), with a drop of 72 metres (236 ft), according to the following segments:
- 1.3 kilometres (0.81 mi) north-east, up to a bend in the river;
- 0.9 kilometres (0.56 mi) towards the east, then towards the northeast, up to a bend of the river corresponding to the discharge of a stream (coming from the northwest);
- 1.0 kilometre (0.62 mi) to the east passing near the Île d'Orléans Heliport and crossing the route 368, to its mouth.[1]
The Savane river flows over a sandstone of a hundred metres at low tide, or on the west bank of the Chenal des Grands Voiliers whose width is 9.0 metres (29.5 ft) at this place. This mouth of the Savane river faces Île Madame which is 2.8 metres (9 ft 2 in) to the east. This channel is crossed by the St. Lawrence River. This mouth is located 1.7 metres (5 ft 7 in) south of the village centre of Saint-François-de-l'Île-d'Orléans.
