On the River

River Safety

Our 300 shoal markers provide safe navigation from the Bateau Channel to Brockville in Canada and cape Vincent to Morristown in the US.

Environment Support

We are proud to be connected with other organizations which support and promote environmental awareness and preservation


We provide resources and information to the entire 1000 Islands Community.

Why Your Membership Matters

Each year more than 300 shoal markers are placed throughout the 1864 Islands. TIA is responsible for placement in Canadian waters and in partnership with Save the River for placement in American waters. Think how dangerous the river would be if there were no shoal markers. For the safety of all of us, our family, friends and visitors who boat in the Thousand Island region, please be a TIA member and supporter.
