Lake Ontario water level

We could not match Lake Ontario to an active U.S. Geological Survey level gauge. Many natural lakes are only measured by a dam operator, a lake association or a staff gauge on a dock, and those numbers are not published in a form we can read every day.
For now the best places to check are the lake operator, the New York wildlife or parks agency, or a local marina. Wind and weather for Ontario are still live on the conditions page.
