LakePulse Web Atlas and Water Portal

By using satellite imagery and spatial modelling techniques, we will extend measurements from 100s of sampled lakes to many 1000s of lakes to provide interactive, web-based maps of lake health nationwide. These methods will allow us to go well beyond the capabilities of any current monitoring program.

Without these advanced techniques, the LakePulse Survey and the data archives of our partners would cover less than 1% of Canadian lakes because of the immense number of lakes in Canada!

The interactive, web-based maps will show:

Past conditions

Maps of the pristine state of lakes before human impacts describing the baseline conditions.

Present conditions

Current lake health, such as key lake and watershed variables.

Future conditions

Forecasts of future lake changes due to land-use and climate changes.

Key stressors

Key stressors, by region, and their impacts on lake health.


Assessments of the impact of environmental changes on ecosystem services.

Societal costs

Assessments of the costs and probability of lake degradation.

LakePulse Web Atlas and Water Portal 5-year timeline

2017 - The LakePulse Database on lake health is being built. It integrates existing datasets from our partners. It also integrates data collected during the 1st field season of the LakePulse Survey (summer 2017).

2018 - The national database continues to grow. A web interface is being developed to help lake associations, municipalities and other organizations share their data. An Automated LakePulse Report system is being designed to compare lake data entered via a web interface accessing the LakePulse Database.

2019 - A link to a mobile app is provided to encourage community-based monitoring by facilitating the sharing of lake and water quality observations with large-scale lake databases, such as our LakePulse Database. Basic lake reports on a limited number of lakes are provided from our Water Portal.

2020 - The web interface begins providing maps of lake and water quality. More advanced analyses are being developed, such as the distribution of human impact factors and their effects on lake health. The Automated LakePulse Reports are enhanced with more lakes and enhanced features.

2021 - The addition of satellite sensor data estimating lake water quality across Canada (such as chlorophyll-a, cyanobacteria blooms, turbidity, water clarity and light penetration) allow Automated LakePulse Reports on many more lakes to be downloaded from the Water Portal. The online interface gains enhanced regionalization features from the spatial modelling efforts.
