Our 300 shoal markers provide safe navigation from the Bateau Channel to Brockville in Canada and cape Vincent to Morristown in the US.
TIA – Shoal Marker Reporting
TIA promotes river safety. Our 300 shoal markers are placed throughout the Thousand Islands from the Bateau Channel to Brockville in Canada and from Cape Vincent to Morristown in the US.
TIA shoal markers are white with a distinct orange triangle to indicate a hazard per regulatory standards. These markers have an identification decal indicating property of TIA with reference to the TIA website and email. There is also a QR code that can be scanned using a QR reader app on a smartphone.
Due to various reasons from conditions on the river, from time to time some of these shoal markers break loose and drift away or wash up on shore and this needs to be reported to TIA. If you notice a missing marker, please email us at firstname.lastname@example.org.
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.
