Low water alert!

Water levels in Lake Ontario and the upper St. Lawrence River are lower than average this spring. Low water levels are anticipated throughout the summer. Visitors should exercise extra caution when approaching park islands and docks.
Low water levels have affected dock installation at some park islands where docks cannot be safely accessed.
The following docks are out of service:
  • Gordon East dock
  • Gordon oTENTik dock
  • Beau Rivage – one small Floating Dock in the Northwest and one in the Southeast
  • Beau Rivage - Service Dock
  • Aubrey Service Dock
  • Camelot South Dinghy Dock
  • Mulcaster Camping Dock (access to campsites from main dock)
