What is the greatest recorded depth of Lake Ontario according to NOS?

The greatest recorded depth of Lake Ontario is indeed 802 feet. This depth is a crucial piece of information, as it reflects the lake's overall size and geology. Knowing the maximum depth is important for various reasons, including navigation safety, ecological studies, and fishing practices, as deeper areas can be habitats for different species compared to shallower regions.

Moreover, understanding the depth helps inform water management practices, the potential impact of invasive species, and the effects of climate change on the lake's ecosystem. Accurate knowledge of the lake's depth allows for safer boating operations and helps resource managers ensure the sustainability of aquatic environments.

The other depth choices provided do not represent the maximum recorded depth of Lake Ontario and therefore are incorrect.
