SECTION 6: Other Interests Q 6.1: How can the regulation of Lake Ontario outflows impact commercial navigation?
• The construction of the seaway and power project opened the Great Lakes to ocean-going navigation. Outflows exceeding design limits in the regulation plan can result in severe water velocities and cross currents in the river, including at key points such as at entrances to navigation locks. In addition, very high flows at the Moses-Saunders hydropower dam reduce the available draft on Lake St. Lawrence due to a drawdown effect at the dam and immediately upstream. By contrast, very low outflows can result in extremely low levels in downstream areas of the Seaway and at Montreal Harbour, limiting the ability of vessels to transit the channels and/or approach docks.
