Welcome to the National Lake Blitz!

And home of the Lake Biodiversity Photo Challenge

Watch this 2 minute video to learn all about the Blitz!

Helping people in Canada understand climate change impacts on the health of our lakes.

From June to September 2021, Lake Blitz participants across Canada will help create a ‘snapshot’ of Canadian freshwater temperature by collecting readings at their local waterbody and by literally taking a snapshot of their location on the lake and the colour of the water in the lake.

National Lake Blitz Instructions & Resources

Project Overview

Blitz: a sudden, energetic, and concerted effort, typically on a specific task

The Living Lakes Canada National Lake Blitz Project was born out of the continuing need to normalize water stewardship and help Canadians understand climate change impacts on the health of our lakes, river, wetlands, streams, and groundwater. The Lake Blitz  demonstrates that all you need as a citizen scientist is a thermometer, a camera, and a body of water that you are curious about and would love to help steward. Living Lakes Canada is looking to recruit organizations and individuals in 5 targeted sub-basins in Canadian watersheds to help spearhead this water stewardship initiative across the country.

Volunteer Commitment

Participating in the Lake Blitz is simple and fun! Once you’ve signed up as a Lake Blitz Volunteer, either on your own or with your local water stewardship group, a Lake Blitz Test Kit will be mailed directly to you or your local stewardship group  with detailed instructions on how to use the equipment. Lake Blitz Coordinators will send reminders ahead of sampling days with tips and tricks on producing the most valuable data possible. Participants will be highlighted throughout the event as a way to recognize the water stewards stepping up to protect Canadian freshwater from the impacts of climate change. 

Required Equipment:

  • Lake Blitz Test Kits (provided by LLC)
  • Camera
  • Cellphone or Computer

Lake Blitz Sampling Process:

  1. Create your account on the Water Rangers App 
  2. Select a sample site on your local lake (shoreline, end of dock) that you can return to 1-4 times per month from June to September
