Sockeye is commercially the most important of the half a dozen
species of salmon found in the Fraser River. It is also key to
the Native food fishery and accounts for over 50 percent of the
Native catch. The Alouette River once supported wild runs of
sockeye and Chinook salmon - both commercially valuable fish.
Both are now gone.
Trade and manufacturing, service industries, and tourism all
thrive along the river. The region is also known for its marine,
road, rail, and air transportation facilities. Much of the
development in this environmental neighbourhood is on a floodplain.
Diversion of water by the construction of a dam in the 1920s
dried up portions of the stream bottom used by salmon to make
their gravel nests. The water was diverted to another watershed
to produce power.
In a remedial project that is making environmental history,
a community of stakeholders, the Department of Fisheries and
Oceans, the Ministry of the Environment, Lands and Parks, and
BC Hydro have teamed up to put into effect a water use plan.
According to this plan, 15 percent of the annual discharge
of the river would be returned to the river.
Negotiations have been going on with BC Hydro to return minimum
flows for the fish so that a once dried-up channel can be restored
to flow year round. It is hoped that hatchery-raised salmon
released in the restored channel will soon return to spawn
naturally. Other fish such as trout will also benefit.
