Jordan Pond, Acadia National Park, Maine

Summer flowers growing on the shore of Jordan Pond.
9 Great Ponds are located within the park: Aunt Betty Pond, Bubble Pond, Eagle Lake, Jordan Pond, Lower Hadlock Pond, Upper Hadlock Pond, Witch Hole Pond, Round Pond and Lake Wood.
Some of the factors that make Acadia's lakes and ponds so beautiful are also what makes them so fragile. They are freshwater holding tanks, collecting rainwater from the sky and surrounding hillsides. As a result, they collect pollutants. Scientists conduct research on and in Acadia's lakes and ponds to best inform management decisions by park staff.
