Swimming and boating at Richelieu R (Lake Champlain) at Rouses Point

Low water changes a lake fast for boaters. Some ramps get shorter or close, docks may be moved, and rocks and sandbars that are usually well under the surface come within reach of a prop.

At 51 °F the water is cold. Even strong swimmers can struggle within minutes, so keep swims short and close to shore.
