Marked Shoals


Map is presented for illustration only and not for navigational purposes. It reflects the vast territory of our River Community and marking of dangerous shoals in Canadian waters based on the approximate locations – they will be updated when verified by GPS tracking. This is an essential service of our not for profit organization. Please be a TIA supporter – we rely on membership and donations to be sustainable.

Due to seasonality, varying water levels, vandalism and equipment failure, the Thousand Island Association disclaims any liability for the absence of any of its shoal markers from time to time.
