The Coquitlam River is a 46 km long right tributary of the Fraser River in the southwest of the Canadian province of British Columbia .
The Coquitlam River rises 40 km northeast of Vancouver in the Coquitlam Ranges , a mountain range of the Pacific Ranges . It flows in a predominantly southerly direction through a wide glacier-shaped valley and flows into the upper northern end of Coquitlam Lake after 15 km . The water level of the formerly natural lake has been raised by a dam since the beginning of the 20th century. The water is led from Coquitlam Lake for the purpose of generating energy via an underground 3.6 km long pipeline to Buntzen Lake further west . Its water drives the turbines of two hydropower plants located on the Indian Arm . The 18 km long lower course of the Coquitlam River thus receives almost no water from the lake and is now mainly fed by Or Creek , which flows into the Coquitlam River just 2 km below the dam. The Coquitlam River flows between the towns of Coquitlam in the west and Port Coquitlam in the east in a southerly direction and finally flows into the Fraser River one kilometer below the Pitt River. 5.5 km above Coquitlam Lake, the mean discharge is 6.69 m³ / s.
The river name "Coquitlam" is probably derived from the Indian word for a fish.
