Summary
The St. Louis River Estuary is the confluence of the St. Louis River with Lake Superior. At 12,000 acres, the St. Louis River Estuary is the largest freshwater estuary in North America and is considered by the Minnesota Department of Natural Resources to be the headwaters of the Great Lakes. Over the past 150 years, industry and other human activity disrupted and altered natural habitats at this estuary, as shorelines and near shore areas were dredged and developed, and chemical contamination impacted the waters, according to the DNR. People recognized that legacy sediment contaminants needed to be remediated and damaged habitat needed to be restored. This work started decades ago and continues today. The Paddle & Portage Podcast team recently traveled to the estuary for a paddle trip. Joining the podcast duo were staff from the Lake Superior Reserve and the St. Louis River Alliance. This episode is supported by our listener-members, and by Cooke Custom Sewing, Loons Nest Coffee, and Friends of the Boundary Waters.
