Lakes Begin Their Seasonal Rise
Precipitation across the Great Lakes basin was above average during April.
All lakes levels rose, which is consistent with the expected pattern of seasonal rise. The monthly mean water level on Lake Erie rose 9 inches from March to April, remaining about 3 inches above its long-term average. Lake St. Clair was also above its long-term average for April, while water levels on Lakes Superior, Michigan-Huron, and Ontario were below their LTAs.

Steady Start to Seaway Shipping Season
Cornwall, Ontario (May 7, 2025) – Despite ongoing global economic uncertainties, early St. Lawrence Seaway activity highlights the stable movement of goods supporting North American trade.
The Seaway’s 2025 navigation season is off to a good start, with traffic reaching 4.5 million tonnes at the end of April, a 3.7% increase compared to 2024. Strong movements of grain, dry and liquid bulk cargoes offset a slower start in iron ore and coal movements.
“We’re seeing steady performance, which is encouraging given today’s economic climate,” said Jim Athanasiou, President and CEO of the St. Lawrence Seaway Management Corporation. “With tariffs and other pressures still unfolding, it’s too early to know the full extent of what lies ahead. But the results to date suggest that the Seaway corridor continues to do its job, reliably and efficiently.”
