other First Nations living along the Fraser River. European settlers first arrived in the region in the mid-1800s and began using the river for their own purposes. The first dam was built at the mouth of Coquitlam Lake in 1892 to provide a source of drinking water for the growing colony of New Westminster. In 1905 the Vancouver Power Company completed construction on a second dam and a tunnel to nearby Buntzen Lake for power generation. As a result, a large portion of the Coquitlam River's flow was diverted out of the watershed altering the hydrology of the river. In response to increased demand, another larger dam was completed in 1915, however unlike previous dams, fish access to the lake was completely blocked. further impacting the river's ecology. The watershed was logged extensively throughout the 1900s which has resulted in heavy sediment loads to occur during high precipitation events. Throughout the 1950s and 60s it was also common practice to extract gravel directly from the stream bed, although this stopped in 1965 when the B.C. Gravel Removal Order was passed. Modern The Coquitlam Lake dam continues to provide power to the residents of Metro Vancouver and is owned and operated by the provincial energy authority, BC hydro. The lake is also one of three reservoirs used by Metro Vancouver and provides drinking water to 900,000 people. The flow reduction caused by the dam and the water diversion to Buntzen Lake affects fish and wildlife in the river and surrounding riparian zone. The barrier created by the dam restricts migration between the upper and lower parts of the watershed, which impacts salmon species in particular who used the lake as a hatching site. As a result, sockeye salmon have become almost entirely extirpated in the Coquitlam River. The dam also reduces the accumulation of woody debris in the lower reaches of the river which could be used for habitats. There are several popular parks and trails along the banks of the river including Coquitlam River Park, Lions Parks, and Gates Parks. The river is also popular with local fishermen. Conservation and threats Conservation groups There have been numerous initiatives to address and educate the public about the issues that threaten the Coquitlam River. These began in 1996 with the Coquitlam River Watershed Community Initiative, and continue today with others, such as the Coquitlam River Watershed Society established in 1998. Salmon To
