IISD Experimental Lakes Area (brochure)

Take a look inside the world's freshwater laboratory!

IISD-ELA is an exceptional natural laboratory comprised of 58 small lakes and their watersheds set aside for scientific research.

Located in a sparsely populated region of northwestern Ontario, Canada, it is one of the only places in the world where it is possible to conduct experiments on whole ecosystems.

For the last 50 years, our unique research approach has influenced billion-dollar decisions of governments and industries. It has generated more cost-effective environmental policies, regulations and management—all in the name of keeping our water clean.
