The Bridge River (literally translated as "Bridge River") is a 142 km long right tributary of the Fraser River in the Canadian province of British Columbia . The river name comes from a bridge near the mouth of the river, which spanned the Fraser River in the 19th century.
River course
The Bridge River has its origin in the Pacific Ranges , a part of the southern Coast Mountains . It forms the outflow of a glacial edge lake that has formed below the Bridge Glacier . The Bridge River flows in a predominantly easterly direction to the Fraser River. In 1961 the Bridge River Power Project was completed. It includes three dams, two of which are on the Bridge River. The Lajoie Dam dams Downton Lake on the upper reaches of the river . This serves to regulate the larger reservoir below, Carpenter Lake , which is dammed by the Terzaghi Dam .
Below this dam, the Bridge River flows 38 km to its mouth 10 km north of Lillooet . Little water still flows in the riverbed of the Bridge River. The water that flows into the Fraser River at its confluence comes mainly from the left tributary Yalakom River . The confluence with the Fraser River lies on a double canyon, which was formed by the two rivers, which are forced through a narrow river bed here and are thus reminiscent of a fountain. This place is now called Lower Fountains . Upper Fountains is a point several kilometers upstream on the Fraser River where the parish of Fountain is located.
The water of the Bridge River is diverted from the Terzaghi Dam to generate electricity to Seton Lake to the south , an originally natural lake, the water level of which, however, has been raised by 3 meters by a dam. From here the water is also artificially diverted via the Seton Canal for energy production and flows into the Fraser River below the mouth of the Seton River .
The catchment area of the Bridge River covers 4660 km². Its mean discharge was 101 m³ / s before the damming of Carpenter Lake at the site of today's Terzaghi Dam.
Fishing
Due to the strong current at the point where the two rivers - Fraser and Bridge River - meet, the most important salmon fishing spot on the Fraser River was and still is . Since the water of the Bridge River has been largely diverted since 1961, with the completion of the Bridge River Power Project, and flows a few kilometers south of Lillooet into the Fraser River, salmon fishing on the Bridge River has come to a standstill.
