It takes a watershed
DataStream works across sectors and jurisdictions to transform collaborative water stewardship in Canada.
Who we work with
We work with monitoring initiatives that want to share their water data openly
Where we work
DataStream is active in five regions from coast to coast. Our data hubs are delivered in collaboration with regional monitoring networks.
All regions
Our regional data hubs bring water quality data together across sectors and jurisdictions — in standardized, accessible formats that make it easier to discover and use.

If we’re going to keep pace with climate change and other threats, we need to do things differently
Community-based monitoring (CBM) mobilizes energy, engagement and knowledge from the ground up to protect the freshwater ecosystems on which we all depend. These programs are generating much-needed information on watershed health. And, when brought together, this data can generate powerful new insights across distances and timescales that are beyond the scope of any single monitoring initiative.

Supporting monitoring where it’s needed most in Atlantic Canada
For nearly two decades, Atlantic Water Network has been helping 100+ water-monitoring organizations across Atlantic Canada track the health of their watersheds.
Using data to fight Lake Winnipeg’s phosphorus problem
Lake Winnipeg’s watershed spans nearly a million square kilometres across four Canadian provinces and four U.S. states. Each spring, when the snow melts across that vast territory, it carries a tsunami of phosphorus into the lake. And that’s a big problem.
Garden River First Nation takes water monitoring into their own hands
Located just east of Sault Ste. Marie, Garden River First Nation sits along the St. Marys River — the major artery connecting Lake Superior to Lake Huron. Here, inland lakes, rivers and streams teem with chinook salmon, northern pike, walleye and more.
Convening
DataStream brings diverse groups together to support collaborative and inclusive approaches to water issues.
