The National Park Service reports a 25% increase in eagle aeries along the Mississippi River, according to an article in The Star Tribune.
Seven new aeries have been spotted along the river between Dayton & Hastings. Ramsey County Parks officials attribute the rise in bald eagle population to the effectiveness of the 1972 Clean Water Act.
The Clean Water Act has improved the Mississippi River's fisheries, allowing eagle parents to provide more for their young.
Eagle aeries have been sighted closer and closer to urban areas. One is near the Minneapolis-St. Paul International airport, another along Interstate 694 near Fridley.
