Norwalk Islands


The Norwalk Islands are a chain of more than 25 islands amid partly submerged boulders, reefs and mudflats along a six-mile stretch and mostly about a mile off the coast of Norwalk, Connecticut, and southwest Westport, Connecticut, in Long Island Sound.
The islands are used for several different types of recreational activities, including camping, boating, kayaking, swimming, bird watching. Ownership of the islands varies, with about a half dozen held in private hands, some owned by the governments of Norwalk or Westport and some are part of the Stewart B. McKinney National Wildlife Refuge.
Various laws protect the islands, including town ordinances, the Coastal Barrier Resources Act, the National Wildlife Refuge System Administration Act of 1966, and the Endangered Species Act. On a clear day, Manhattan's skyscrapers are visible.
Geologists generally consider the islands to be terminal moraines —material left by glaciers—deposited about 17,500 years ago as the ice cap paused in its retreat northward. Above water, the moraines are characterized by various rocks, gravel, sand, silt and clay, sometimes sorted out by waves. The Captain islands in Greenwich to the west are part of the same moraine, and submerged parts of the same moraine are located between the Norwalk Islands and Charles Island, off Milford, to the east.
Some historians have speculated that rocks from the islands were used as ballast for sailing ships returning to New York, where the rocks may have been used for cobblestones.

Recreation

No fresh water is provided at any of the islands.

Kayaking

The islands are popular with kayakers, with some paddling all the way from New York City. Tidal currents are gentle, the mainland is always visible and the electric power plant on Manresa Island helps with navigation. Public boat launches and beaches are nearby, and some businesses in Norwalk rent kayaks.
The South Western Regional Planning Agency published a brochure for kayakers describing a "Norwalk Islands Canoe and Kayak Trail" showing full-day and half-day loops. Guided tours are also available by kayak.

Fishing, clamming and hunting

Striped bass, bluefish, fluke, flounder, false albacore, bonito, trout, and dogfish can be caught off the islands. Some clamming beds off the islands are seeded.
In duck-hunting season, hunters may hunt below the mean high-tide line. Deer can be hunted on the privately owned islands with the owner's permission.

Bird watching

Rookeries were previously on many of the islands, but now most are on Cockenoe. Herons, egrets, black cormorants can be seen on Cockenoe.

Wildlife

Deer swim to the islands. Harbor seals are increasingly seen at the southwest end of Sheffield Island, although authorities have asked boaters to remain at least from them in order not to disturb them. The Marine Mammal Protection Act prohibits harassing the animals and sets limits on how close observers may get.
Flora include thorn thickets, wild blackberries, black cherry, bittersweet, sassafras, juniper and honeysuckle.
Many birds are found on Sheffield Island and more than elsewhere, according to a brochure published in 2001 by the South Western Regional Planning Agency, but according to a July 2007 article in Darien, New Canaan & Rowayton magazine, Cockenoe island is now the largest home for birds, who have been in decline on the other islands. Sheffield Island, according to the planning agency brochure, has a "considerable nesting potential" for osprey, herons and other migratory species. Many wading birds, shore birds, songbirds and terns live on the island, including the roseate tern. Brant, scoters, black duck and other waterfowl can be found in the waters surrounding the island.

Largest islands

Chimon Island

At Chimon is the largest of the islands and is located in the middle of the group and a bit less than a mile to the southeast of the entrance to Norwalk Harbor. The island is part of the Stewart B. McKinney National Wildlife Refuge.
The north and west coasts of the island are gravelly, and boulders are strewn along the south and east coasts. Although boaters may land at the three-acre beach at the northwest shore during the day, year round, access to the rest of the island is restricted from April 1 to August 15 each year. No overnight camping is allowed. Chimon Island is at.

Cockenoe Island

Owned by the Westport town government, the island has almost all the bird rookeries in the chain. Herons, egrets, black cormorants can be seen on Cockenoe. The cormorants' guano, which leaves some of the rocks white, is toxic to the trees and kills them off after the birds nest in a spot for less than a year. Overnight camping is allowed by the town Conservation Department, but for only four parties per night. Cockenoe Island is at. It is named after the prominent Indian translator, Cockenoe.

History

An early rumor about the island was that William Kidd buried a treasure there. In the 19th century, the island was a working farm with a farmhouse, barn, and livestock. The business eventually turned into a whisky distillery, which the federal government raided in 1870. In the 1960s, The United Illuminating Company planned to build a nuclear power plant on Cockenoe. Due to concerned local residents and the threat of eminent domain, Westport bought the island for $200,000 in 1967.

Shea Island

Once called "Ram Island", the isle was renamed after Daniel Shea, a Congressional Medal of Honor recipient from Norwalk who died in the Vietnam War. Owned by Norwalk city government, the island is just northeast of Sheffield Island and about south of Manressa Island.
Along with Grassy Island, Shea is open to the public from May through Columbus Day, and campers with a permit can stay overnight. Two solar-powered restrooms are available in season, and there are 16 campsites. The entire shoreline is strewn with rocks and boulders, making it a more difficult place to approach by boat. Shea Island is at.

Sheffield Island

At, Sheffield is the second largest island in the group, and the most southerly, located about from the Norwalk coast and just southwest of Shea Island. The entire shoreline is strewn with rocks and boulders.
Many bird species nest on the island. Sheffield is also one of the best places to see seals. The Maritime Aquarium at Norwalk organizes boat trips circling the islands, including a cruise to see the fall foliage and a winter cruise to see harbor seals and waterfowl.
Part of the Stewart B. McKinney National Wildlife Refuge, the island is controlled by the U.S. Fish and Wildlife Service, which closes it to the public most of the year in order to protect the bird nesting areas, The public is usually restricted to the around the Sheffield Island Light, which the maintains, although a trail has been created to allow the public controlled access. In the summer, the association arranges tours for people to visit the lighthouse and picnic there. On Thursday nights, clambakes and on Friday nights, sunset cruises are held. The lighthouse, built in 1868, was a navigational aid until about 1900. Sheffield Island is at.
