A new era for tracking the health of the Great Lakes
October 25, 2021
If you’ve ever wondered about the health of your local river or lake, seven million open data points are now at your fingertips.
Information ranging from lake temperatures to levels of nitrates in the water is available on Great Lakes DataStream, a new online platform for sharing water quality data from across Ontario and Quebec.
It’s going live during international Open Access Week, a global celebration of the power of open data – information that is free to look at and reuse – that runs until October 31.
“From daily COVID-19 rates to water quality at the beach, we’re seeing a global trend towards more data being made accessible to everyone”, explained Carolyn DuBois, who heads Great Lakes DataStream. “Open data is powerful – it helps people make more informed choices.”
Because DataStream is open access, anyone, including scientists and policymakers, can explore the data while being confident in its integrity thanks to blockchain technology. Just last year, data accessed on DataStream helped fill gaps in the WWF Watershed Reports.
“Having the ability to dig in, and look, and try to understand water quality through data can be a very empowering experience,” explains Larissa Holman of Ottawa Riverkeeper, one of many water monitoring groups to have shared their data on the platform. “The power of providing people with relevant information about their local waterway should never be undervalued. It can be an incredible way to motivate them to either protect or to improve it.”
“Behind every data point is a person,” says DuBois. “We work with community-based monitoring programs, Indigenous Nations, watershed groups, and all levels of government. We’re excited to be working with passionate water champions from Thunder Bay to Montreal.”
With Great Lakes DataStream joining existing data hubs in the Mackenzie River Basin, Atlantic Canada, and the Lake Winnipeg Basin, DataStream is Canada’s largest independent water data platform – with data from 12 of Canada’s provinces and territories.

Community science on the agenda in the Great Lakes
Since DataStream began in 2016, we have focused on amplifying the important work of community-based monitoring groups. We’re excited that community science has been a central theme at the many gatherings we’ve attended over the past few months throughout the Great Lakes region.
Paddling and protecting the Madawaska
For the past four years, Madawaska Kanu Centre’s office team have been tracking the river’s water quality. Once a month, unless the conditions are too icy, they measure parameters like pH levels, dissolved oxygen and transparency.
