Increased flow Oct. 4 - 8
During the
week of October 2, Nanaimo Forest Products and the City of Nanaimo will be
releasing water from the Fourth Lake and Jump Creek reservoirs to provide a
temporary pulse flow to the Nanaimo River. A partnership between the Nanaimo
Fish Hatchery and the two water licensees, in concert with Department of
Fisheries and Oceans and the Ministry of Forests, Lands and Natural Resource
Operations has existed for a number of years. The parties come together
annually to coordinate an early fall flush of fresh, cool water to encourage
Chinook salmon waiting in the Nanaimo River estuary to move upstream to begin
spawning.
The pulse release
will be noticeable starting Wednesday, October 4, and will taper off by the
weekend of October 7-8.
Through careful management of the reservoirs,
there is sufficient reserves available to be able to facilitate the pulse
release, despite this year's drought.
Mature Chinook salmon typically wait in the tidal portion of the
Nanaimo River, until the first fall rains provide enough flow to move upstream.
The pulse release provides that flow, and over the past several years has aided
in recovery of this species.
"With the recent rain, flows
have increased slightly, but not significantly enough to trigger the Chinook in
the lower Nanaimo River to migrate upstream. A pulse release again this year
will definitely be beneficial."

Hatchery
