The U.S. and Canada announced Wednesday that they have finalized a plan for restoring and protecting Lake Superior's water quality.
A 96-page document from the Lake Superior Partnership outlines major threats such as invasive species and climate change. It also lists priorities for preserving the relatively clean waters, including ending the release of nine toxic substances.
"Although the Lake Superior ecosystem is in good condition, there are serious threats including: aquatic invasive species, climate change, reduced habitat connectivity between the open lake and tributaries, chemical contaminants, substances of emerging concern, and habitat destruction," the report states.
