Why Your Membership Matters
Each year TIA places close to 300 shoal markers throughout the 1864 islands in both Canadian and American waters. It is an expensive program funded by TIA membership fees and donations. 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.
