About this Site

Over the past 20 years, this site and its associated resources have led thousands of people to discover the joy of waterfalling. The site is continuously improved with help from the Ontario waterfalling community.

This site compliments the book published by Firefly Books (© Firefly Books 2003, 2011, 2018). Written by Harris and illustrated by award-winning photographer George Fischer, this is another resource that can help you to discover these special places, either in person or virtually.

This is the 7th generation of this web site. It was designed and first uploaded in 2021 as a replacement for the 6th generation site released in 2018. The first web site, "Waterfalls of Southern Ontario", went live in 1999. was registered in 2011.

Unlike other waterfall web sites, this site does not knowingly provide photos or directions to waterfalls located on private property. Most people known that it would be irresponsible to guide people to places that they aren't allowed to visit.

SPECIAL NOTE: If you see a waterfall that should not be included here due to private property, please send an email to mark at It is against this site's policy to publish directions to private property.

This web site keeps growing because of the contributions of literally hundreds of members of the Ontario waterfalling community. Over the past 20 years, countless tips, corrections and photos have been provided by site users, book readers, and the 35,000 members of our Facebook group.

Thanks to EACH OF YOU for helping to bring the joy of waterfalling to thousands of people!

If you browse this site you will see many photographs that have graciously provided by many, many dozens of people. For every photo that you see, there are information snippets that have be incorporated into the site's content.

I coded and designed most of the site by myself. Technical support from Dan Good was invaluable in helping me to solve some of the more challenging CSS dilemmas. Darlene Munro provided some design elements, and I received many useful comments from the Facebook Moderator Team. Anneke van Dyk provided design advice. Jeff Dingwell provided guidance for the 6th generation site.

Over the past few years, the Facebook Group associated with this project has grown dramatically. By spring 2021, we had exceeded 30,000 members. It has provided an enormous amount of waterfall information, much of which is reflected on this site. I strongly encourage you to join the group!

Running a group of this size would not have been possible without the help of the Facebook moderator team. Each of these awesome people brings different strengths and experiences. Thanks so much for the efforts of Ann Behnke, Anneke van Dyk, Darlene Munro, David Reid, Gary Smith, LA Mabo, Russ Higgins, Sean Christopher, Shawn Brule and Terry Lupton. Thanks also to retired moderator John Bruce Leigh.
