The St. Lawrence River is threatened by numerous problems. Read on to learn about a few key issues facing the St. Lawrence River ecosystem.
Aquatic invasive species are one of the most critical problems facing the St. Lawrence River and Great Lakes. With 186 species introduced into the River and Lakes, the region’s ecosystem is bending under the weight of these introduced species. Some scientists worry that the ecosystem of the Great Lakes and St. Lawrence River may be close to collapse because of these species.

Water Levels Regulation
With a massive hydropower dam blocking the River in the Massena/Cornwall region, water levels on the Upper St. Lawrence River are manually regulated. The management plan that has been in place for the past 50 years has caused significant damage to tens of thousands of acres of wetlands in the region.

St. Lawrence Seaway
The St. Lawrence River is the only pathway for ships to enter the Great Lakes. Unfortunately, ships bring along a host of problems, from oils spills and accidents, to winter navigation damage, and constant threats to expand Seaway infrastructure. Save The River has been an advocate for more sustainable shipping on the River.
