Registration will open on March 1st, 2024 for the
4th Annual National Lake Blitz!

The National Lake Blitz is an annual volunteer citizen science program with the goal of encouraging the widespread monitoring of lakes across Canada by providing accessible tools, resources and support to everyone interested in monitoring their local lakes.

Welcome to our community of volunteers who deeply care about lakes and want to take action! 

At their chosen lake from May to September, Lake Blitz volunteers collect temperature readings, shoreline photos of their location and the colour of the water, and more. All the data that’s collected is added to the interactive Lake Observation Map that can be viewed in real-time.

The sister event of the Lake Blitz is the Lake Biodiversity Photo Challenge, which will run from June to July 2024.

Check back for the 2024 Lake Blitz online registration form starting March 1st.

Visit the Lake Blitz Program Page to learn more about the program and its objectives.
