2025 was a great year for tool building and turning data into action!

In 2025, Water Rangers focused on strengthening shared infrastructure for community-led freshwater monitoring. We launched a brand-new data platform, published major reports like the Watershed Reports, and expanded the suite of tools we offer communities to measure water health.

Join us in celebrating our team, our friends and collaborators, and our achievements in the past year! It was a year of building core systems and partnerships, and seeing those pieces start to connect in practice. Ready to dive in?

What people said

"Thanks to the support of Water Rangers and Ocean Week Canada, students got hands-on with Water Rangers water quality test kits, exploring the chemistry of their local watershed with the curiosity of young scientists." - Sarah Blenis, Hammond River Angling Association

"Students are always excited when they know it's water measure day! We go once a month and it is so interesting to hear them talk about the changes they see and their hypotheses as to why it's different this time. These outings play an important role in the development of their scientific competencies. They aren't students doing science, they are citizen scientists collecting data in a meaningful way." - Carrie Antoniazzi, teacher

"Water Rangers Freshwater Explorer Testkits are great tools for those interested in protecting local waterways! They’re a fantastic way for community members to get involved in meaningful, hands-on environmental monitoring. Overall, Water Rangers does a great job empowering communities to learn about, care for, and advocate for their freshwater ecosystems!" - Kaeley Cole, BARC
