Jordan Pond is an oligotrophic tarn in Acadia National Park near the town of Bar Harbor, Maine. It covers 187 acres (76 ha), with a maximum depth of 150 feet (46 m) and a shoreline of 3.6 miles (5.8 km).
The pond was formed by the Wisconsin Ice Sheet during the last glacial period. It is flanked on the west by Penobscot Mountain and to the northeast by the two mountains known as "The Bubbles". The southern end, and outflow, are limited by the natural Jordan Pond moraine, which has been supplemented by a small dam.
The pond has clear water, with visibility normally 46 feet (14 m) and occasions of up to 60 feet (18 m) recorded, the deepest in Maine. It serves as the water supply for the village of Seal Harbor. It does not experience dissolved oxygen depletion in the depths of the lake.
Park officials estimate that roughly 60 percent of park visitors will visit the pond, primarily the tea-house at the southern end, at some point in their stay. The pond is ringed by a walking trail, from which branch off trails to or over several other park features. One of the park's original carriage trails runs along a ridge adjoining the pond.
The Jordan family of Seal Harbor, for whom the pond is named, built a farmhouse near the pond. In the 1870s a restaurant known as the Jordan Pond House was built. Under the management of the McIntires, which ran from 1895 to 1946, the restaurant became a regular location for high society events. John D. Rockefeller, Jr. purchased the restaurant and gave it to the National Park Service. The original building was destroyed by fire in June 1979, and a new building was financed through private fund raising. The Jordan Pond House has a gift shop and a restaurant serving lunch and dinner; it is perhaps best known for its service of tea and popovers both on the enclosed veranda and outdoors on the lawn overlooking the pond.
Flora and fauna
Jordan Pond was for a period the type locality for the type specimen for the quillwort species described by Alvah Augustus Eaton and formerly known as Isoetes macróspora var. heteróspora or Isoetes heterospora. It was then thought to be located only in this pond. This is now considered to be a synonym for Isoetes lacustris, which is found in both North America and Europe. Four other quillwort species are also found in the lake, along with three species of pondweed, two species each of rushes, bur-reeds, and carnivorous bladderworts, and at least six other species of plants.
Fish species in the lake include landlocked Atlantic salmon, lake trout, brook trout, rainbow smelt, four species of minnow, banded killifish, three-spined stickleback, pumpkinseed sunfish, and the American eel. The landlocked salmon, lake trout, smelt, sticklebacks, and at least one species of minnow are known to have been introduced and/or stocked by humans.
