Adams River is a river in British Columbia, Canada, which flows into Shuswap Lake. The Adams River is one of the most important sockeye salmon breeding areas in the world. The run occurs in mid-October and can bring millions of fish to a concentrated area near the river mouth.
The Adams River run occurs every year, but every fourth year, the numbers are much higher. 2010 is the latest dominant run. According to Canada's Department of Fisheries and Oceans, the Fraser River sockeye run of 2010 is the largest since 1913, numbering an estimated 34 million fish. At least 9 million of these fish will have returned to the Adams River area to spawn.
