Of the 9 Great Ponds located wholly within Acadia National Park (ANP), Eagle Lake is the largest - 466 acres, with a maximum depth of 110 feet. (Long Pond, which borders ANP, is the largest lake on Mount Desert Island, and is approximately twice the size of Eagle Lake in terms of surface area.) One of the most visited carriage roads in ANP circles Eagle Lake.
Secchi data are available from the early 1980s, annual averages ranging from 8.7m to 12.8m (28-42 ft). A summary of water quality parameters is here. Eagle Lake is the water supply for Bar Harbor.
