Water resources are among the most dominant features of the landscape at Acadia National Park. They are integral to ecosystem health and function and are fundamental to a variety of recreational pursuits including fishing, sightseeing, canoeing, sailing, and swimming. Protection of the scientific and scenic attributes associated with park lakes, streams, and wetlands, and their use as a source of public drinking water, were significant factors in the park's establishment and form the core of the park's water resources program.
Water resources within or adjacent to the park include 14 Great Ponds (lakes greater than 4 hectares/10 acres), 10 smaller ponds, more than two dozen named streams, and 10 named wetland areas. Lakes and ponds cover about 1,052 ha, and wetlands cover about 1,670 ha (equivalent to approximately 7.4% and 10.1%, respectively, of the park's area).
Objectives of the water resource program are to:
In recent years the park has started to develop a core long-term monitoring program for freshwater resources. Two sets of selected lakes have been identified for monitoring the effects of atmospheric deposition/acidification and cultural eutrophication, the two greatest threats to freshwater ecosystems identified in a workshop of water resource professionals. The park also conducts monitoring of benthic macroinvertebrates and periodic bacterial monitoring at park swim beaches.
Recently completed water related research at Acadia includes:
Acadia's water program is conducted in collaboration with the NPS Water Resources Division, Maine Department of Environmental Protection, the Water Research Institute at the University of Maine, and the United States Geological Survey.
