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.

TIA is the only organization placing shoal markers for the River Community - this is an essential service. Think how dangerous the river would be if there were no shoal markers? For the safety of us all, our families, friends and visitors who boat on the river - please be a TIA supporter. We rely on membership dues & donations to be sustainable.
