The Bertrand Creek Augmentation project is a pilot project
funded by a grant from the Washington Department of Ecology to the Bertrand
Watershed Improvement District. This portion of the grant is estimated at about
$65,000.

Bertrand Creek winds through northern Whatcom County, west
of Lynden, before eventually draining into the Nooksack River. The Bertrand
drainage is an area Ecology and others have long focused on due to its low flows
in the summer. Many farmers in the area hold legal water rights to use water from
the creek for irrigation. Over the years, many farmers have switched to drawing
irrigation water from groundwater sources, reducing the impact on the creek,
but late-summer flows have remained lower than optimal. Increasing flows in Bertrand
Creek is important because it provides cool, clean water for fish, including
the endangered Chinook salmon and endangered bull trout.
“This is a great accomplishment between the State, farmers,
tribes, State Fish and Wildlife, and the county,” said Kasey Cykler, water master
for Ecology. “The work to get the permits done and make the project happen is a
testament to the effort and collaboration of all those involved.”
The system aerates the water and disperses the flow so it won't damage the creek |
To increase the flow in the creek, water from local wells is
pumped down a special ramp, aerating it and also dispersing the flow so it
doesn’t scour the stream. Two ramps were built by a local contractor at a cost
of about $1500 each. The ramps are made from aluminum, making them lightweight
and easy to move. The devices will move about 1.1 cubic feet/second of water to
supplement the creek. Water quality is regularly tested before the additional
flow goes into the creek to ensure it meets quality standards and fish needs.
The project was made simpler by using already available
resources. The wells supplying the water are existing irrigation wells that are
finished irrigating for the season, and pumps and water lines were loaned by
area farmers. This “reuse” concept also reduced project costs.
Ecology awarded the watershed improvement district a
temporary water right permit for the project, which runs until Nov. 15, but if
enough rain falls, the pumps could be turned off sooner. Besides the immediate
benefit for fish, data from the project will help determine whether this type
of project could be used in future years and in other places.
