Arnold River (lac aux Araignées)

The Arnold River is a tributary of the Lac des Joncs, which flows into Lake Mégantic. The latter, which also receives the discharge from the Lac aux Araignées, constitutes the main body of water at the head of the Chaudière River, which flows northward to empty on the south shore of the St. Lawrence River. The Arnold River flows through the municipalities of Saint-Augustin-de-Woburn, Piopolis and Frontenac, in the Le Granit Regional County Municipality, in the administrative region of Estrie, in Quebec, in Canada.

The main neighboring hydrographic slopes of the Arnold River are: north side: lake Mégantic, rivière aux Araignées; east side: rivière aux Araignées, Vaseux stream; south side: Morin Creek, Cupsuptic River (Cupsuptic River), (USA), Porter Brook (USA); west side: first east branch of the Magalloway River (USA), Deer Brook (USA), Bergeron River. The Arnold River originates in Arnold Lake (length: 2.4 kilometres (1.5 mi) north–south direction; altitude: 754 metres (2, 474 ft)). This lake is located in the southern part of the municipality of Saint-Augustin-de-Woburn. The mouth of this lake is located 4.8 kilometres (3.0 mi) south of the summit of Mont Gosford. This swampy lake straddles the Canada-US border. A dam was erected at its mouth, giving it the status of a lake. The average flow of the Arnold River is approximately 5 cubic metres per second (180 cu ft/s) and its watershed covers 265 kilometres (164.66 mi). From Lake Arnold, the River Arnold flows on 28.2 kilometres (17.5 mi) divided into the following segments: Upper course (segment de 17.8 kilometres (11.1 mi)) 2.5 kilometres (1.6 mi) towards the north, to the mouth of the Morold Pond, which the current crosses for about one hundred meters; 2.8 kilometres (1.7 mi) north, to a stream (coming from the east); 3.3 kilometres (2.1 mi) north, to a stream (coming from the west); 4.9 kilometres (3.0 mi) eastward, up to the confluence of Morin brook (coming from the south); 3.2 kilometres (2.0 mi) north, to the limit of the township of Woburn; 1.1 kilometres (0.68 mi) north, to a road that it intersects at 0.6 kilometres (0.37 mi) east of the center of the village of Saint-Augustin-de-Wo
