Supporting Indigenous river monitoring and restoration in New Brunswick
December 4, 2023
This is part of a blog series highlighting how water data is being put to use to protect freshwater
“Oh!” says Alexa Meyer as she stands on the banks of the Skutik (St. Croix) River on a cool October day. “A big eel!”
It’s a sight worth celebrating. Meyer manages aquatic conservation for the Passamaquoddy Recognition Group Inc. (PRGI), an Indigenous-led not-for-profit that represents the interests of the Peskotomuhkati Nation at Skutik. And one of their goals is increasing the presence of eels, alewives, blueback herring and other native fish the Nation has traditionally relied on.
For millennia, the Peskotomuhkati have inhabited a big chunk of what’s now southwestern New Brunswick, stretching from Spednic Lake south of Canterbury to Passamaquoddy Bay. It’s an area that encompasses 11 watersheds, including the Skutik.
Today, those watersheds face numerous threats from dams, deforestation, rising temperatures and other human pressures. And that means fewer fish. So, in 2019, the Nation developed a restoration plan for the Skutik watershed. “We are looking to restore as closely as now possible to how the Peskotomuhkati lived in the territory pre-contact,” explains Meyer.
Smart restoration starts with good data
To guide that work, PRGI needed water quality data. They turned to Atlantic DataStream, an open access online platform for sharing water and sediment quality data. Since its launch in 2018, Atlantic DataStream now brings together data collected by 100+ monitoring groups throughout Atlantic Canada.
As a result, PRGI was able to see which groups were monitoring watersheds within Peskotomuhkati territory and pinpoint areas with the poorest water quality. They could also identify the areas that lacked data. With these insights, PRGI launched an ambitious program to start tracking water quality at more than 80 data-deficient sites.
Each month, Meyer and her team use handheld probes to monitor dissolved oxygen, salinity, pH, and other parameters at each site. They’ve also installed temperature loggers to track warming trends. If results are poor, they send samples to a lab for more extensive analysis.
Helping rivers be rivers again
That data has helped PRGI launch a variety of targeted restoration projects. In 2021, for example, they removed collapsed culverts and other structures blocking fish passage, opening up more than eight kilometres of stream.
“Pulling out [those obstacles] restores water flow, allows fish back into that habitat, brings in more oxygen, and prevents excessive sediment blockages,” Meyer explains.
They also planted trees to help stabilize 700 metres of riverbanks where there were problems with erosion and sedimentation.
“We’re trying our best to improve habitat for fish and take an ecosystem approach as well, thinking about all other creatures that live in this area,” says Meyer. And they’re not doing it alone, she adds, pointing to collaborations with other watershed groups identified through DataStream.
Those collective efforts are already making a difference at restoration sites. “The river is allowed to be a river again,” says Meyer. But that’s just the beginning. Guided by good data, she’s looking forward to seeing even bigger wins — and more eels, trout and other native fish — in the coming years.
Discussing water security at the GLOBE Forum in Vancouver
The recent GLOBE Forum in Vancouver brought together innovators and changemakers from across the country who are accelerating the clean economy.
Pacific DataStream launches
Pacific DataStream is live! Launching at the Environmental Flows Conference in Kelowna, our latest regional hub already holds millions of water quality data points from across British Columbia and the Yukon, all open and available for anyone to explore and download. Explore monitoring results from rivers, lakes, and streams, covering a range of parameters, from temperature and dissolved oxygen to lab-analyzed data like nutrients and metals.
Supporting standardized community-based water quality monitoring in the Greater Vancouver region
Nikki Kroetsch is a big believer in the power of community-based creek monitoring. Governments don’t have the capacity to monitor every little waterway, she says, which has led to many stewardship groups doing the work.
