Westbrook Harbor is the western part of the open bight between Cornfield Point and Menunketesuck Island. It has many unmarked submerged rocks and is seldom used as an anchorage; the anchorage in Duck Island Roads is better. The bight is characterized by boulders.
Duck Island Roads, between Menunketesuck Island and Kelsey Point, is a harbor of refuge protected by breakwaters 1,100 feet northward and nearly 0.5 mile westward from Duck Island, with the added protection of Kelsey Point Breakwater on Stone Island Reef. A prominent landmark on Duck Island is a stone chimney. Both breakwaters extending from Duck Island are marked by lights.
Patchogue River, used chiefly by fishing and recreational craft, empties into Duck Island Roads just west of Menunketesuck Island. A channel leads from deep water in Duck Island Roads to the first fixed highway bridge, about 0.6 mile above the mouth. The approach channel is marked by buoys, and the river channel is marked by private aids. A light is on the outer end of the breakwater on the west side of the river mouth. In 2010, the controlling depth was 4.1 feet (5.4 feet at midchannel) to the head of the project about 40 yards below the first fixed highway bridge, except for shoaling to bare well into midchannel from the eastern side of the channel near Buoy 6. The anchorage basin had a controlling depth of 5.6 feet.
Menunketesuck River, sharing the same entrance channel as Patchogue River, is a shallow stream westward of Patchogue River. In 1981, a depth of about 8 feet was reported to the first fixed highway bridge crossing the river above which depths of less than 1 foot are reported.
