Flowing lakes | Adams Lake |
The Adams River is a tributary of the Fraser River in the Canadian province of British Columbia .
It rises in the Monashee Mountains . The upper reaches ("Upper Adams River") of the Adams River flows south to Adams Lake . The underflow ("Lower Adams River") forms the outflow of the lake at its southern end. This flows into Shuswap Lake at its extreme western end. The river is a major spawning area for sockeye salmon in North America. During the salmon migration in mid-October, millions of fish swim to the mouth of the Adams River. Excavations of Secwepemc settlements on the river show a long tradition of salmon fishing in this region. The river also used to serve as a major transportation route for rafting tree trunks in the Adams River catchment area. The Adams River has the status of a British Columbia Heritage River .
River course
The origin of the Adams River are several nameless glaciers at an altitude of about 2000 m in the northeast of the Monashee Range in the Columbia Mountains . The upper reaches of the river largely flows in a south and south-westerly direction through wetlands. He passes two small lakes - Tumtum Lake and Mica Lake. It has sections with rapids and white water . There are several waterfalls below Tumtum Lake. On some stretches the river has a gradient of 5 m per kilometer. After 94 km he reaches the north end of Adams Lake, which is in Shuswap Highland .
Adams Lake has a north-south extension of approximately 72 km and reaches a water depth of 457 m, making it the 24th deepest lake in the world. The lower reaches of the Adams River runs 7 miles down a narrow valley. It flows into Shuswap Lake near the Squilax settlement . The gradient between Adams Lake and Shuswap Lake is 60 meters.
