If you see signs of severe weather approaching move to a sheltered location and follow instructions as provided by the weather warning.

Marine safety and conditions

Many visitors choose to enjoy Thousand Islands national Park by boat. In fact the region is known around the world for the spectacular boating opportunities available here. While boating in the area is generally quite safe there are a number of challenges to be aware of. At certain times of the year traffic can be very high creating congestion and the risk of collisions. Water levels fluctuate often and rapidly, exposing and covering hazards to navigation constantly. Lake breezes are a common occurrence in late summer and can create rough water.  

There are many resources available to help you enjoy a safe day on the water.
