  St. Louis River Estuary National Water Trail
St. Louis River Alliance

Premiered Sep 11, 2020

At the headwaters of Lake Superior lies the Nation’s largest freshwater estuary. Flowing between Minnesota and Wisconsin, the St Louis River Estuary has a rich history.

Unfortunately, Due to unregulated industrial dumping, the St. Louis River was one of the most polluted waterways in the United States. Though after decades of work the River is slowly returning to health.

The St. Louis River Estuary National Water Trail project is a direct result of a cleaner river. The National Water Trail is a multi-use waterway enabling the public to experience the St. Louis River Estuary amidst the urban landscape of the Twin Ports. The Water Trail includes 11 loop trails for paddlers of all skill levels and abilities and is intended for various watercraft use.

By providing access to wild space in an urban area, the Water trail enables more people an opportunity to build their own memories and relationships to the St. Louis River.

As proud managers of the National Water Trail, the St. Louis River Alliance is leading a working group of representatives from MN and WI to ensure its success.

The St. Louis River Alliance is a membership organization of river stewards working together to restore, protect and enhance the St. Louis River.
