Human settlement in the Don watershed extends back 13,000 years to the retreat of the glaciers.

The Don River was named in 1793 by Lord John Graves Simcoe, in honour of his favorite English river - the River Don.

The Don River has 4 major tributaries: West Don River, East Don River, German Mills Creek, and Taylor-Massey Creek.

Combined, the 4 tributaries of the Don River stretch a distance of 273 km.

The West Don River is the longest tributary, stretching a distance of 48.23 km - that's the length of 960 Olympic sized swimming pools!

There are over 143 km of trails in the Don watershed - walking at average speed, it would take you over 40 hours to travel them all!

The Don watershed is home to 172 species of native wildlife, and 441 species of native trees, shrubs, and wildflowers.

Over the past 12 years, more than 50,000 volunteers have donated their time to help rehabilitate and revitalize the Don!
