LakePulse partners all provided substantial support to LakePulse. This included data, logistical support, local and scientific expertise, and scholarships to our students and postdocs.
Quite simply, LakePulse would not have been possible without their help. The funding for this project was provided by the Natural Sciences and Engineering Research Council of Canada

A portrait of lakes across Canada from LakePulse
To assess lake health, our teams traveled across Canada for 3 summers to collect lake data.
664 lakes were sampled and analyzed to create a nationwide dataset.
From this dataset and further analyses by LakePulse, a geomatics team at the University of Sherbrooke developed the LakePulse portal.
To learn how to navigate the portal, check the next few pages.

Credits
This portal presents the result of extensive field work, sample and data analysis, quality control by students, postdocs, research assistants and researchers from 10 universities across Canada which collaborated with provincial and federal governments and other organizations.
See lakepulse.ca for more information on the program and participants.

Design and technical aspects of the portal are carried out by the Université de Sherbrooke. ‘Portal team’: Jelena Juric, Jean-Sébastien Bruneau-Blais, Emma Dubrûle, Virginie Tetreault, Samia Djerroud and Maxime Fradette. Its development is supervised by Yannick Huot.

We thank everyone who has commented and provided feedback during its construction.

Data access
The results presented in the current version of the web portal (phase 1) should not be used for scientific investigation (most were rounded, scaled, binned or otherwise modified to help with presentation and comparisons). They are meant to provide information to environmental stewards, policy makers and the public to understand and compare lakes in the context of others in Canada and their region. LakePulse will release its complete dataset once the students and postdocs have advanced their work and we are fully confident in the dataset.

This said, land use and land cover as well lake and watershed characteristics (size, slopes, etc.) are available and quality controlled and can be used for any purposes (available under the lake Characteristics and Watershed Characteristics to of each lake). The shapefiles of the watersheds and lakes are also provided under the 'Watershed Characteristics' tab of each lake under the 'learn more' section. These are also quality controlled and usable for any purposes.
