The following map is presented for illustration only and not for navigational purposes. It reflects the vast territory of our River Community and our shoal marking program. Please be a TIA supporter – we rely on membership and donations to be sustainable.
The primary objective of our shoal marking program is to heighten boater’s awareness of the importance of careful navigation throughout the Thousand Islands region. Our shoal marking program is not intended, nor should it be used for navigational purposes at any time, and boaters should be aware that only a small percentage of shoals are marked each season.
TIA strongly encourages all boaters to use navigation charts when on the river and to be aware that for a variety reasons, shoal markers do break loose from time to time. As such, previously marked shoals may become unmarked for an extended period of time. Due to the unpredictability of this occurring, the Thousand Islands Association disclaims any liability for the absence of any of our shoal markers from time to time for any reason.
