The Webhannet River is an 8.3 mi river whose 8963 acre watershed is contained entirely within the town of Wells, Maine. The river has five tributaries, including three with official names: Pope’s Creek, Depot Brook, and Blacksmith Brook. Draining a sandy outwash plain left by the last glacier, they run parallel to the southern Maine coastline behind the heavily developed barrier beaches of Wells and Drakes Island. The river flows into Wells Harbor, then empties between a pair of jetties into the Gulf of Maine. The Webhannet watershed includes 1510 acre of land under conservation, including 1167 acre of estuary salt marsh and uplands protected by the Rachel Carson National Wildlife Refuge.

Jetties

In 1961-62, the U.S. Army Corps of Engineers built two rubble-mound jetties to protect the 8 ft channel to Wells Harbor. The north jetty was 580 ft long, the south one 920 ft, and extended roughly from the inner harbor to just past the beaches. A 1-ft-thick bedding layer and core of 3-in. to 150 lb stone was covered with a double layer of stones weighing a minimum of two tons on the landward section and three tons on the seaward sections, for a total of 20,000 tons of stone. The cost for placing the stone was $95,600. In 1962-63, the north jetty was extended 200 ft seaward at a cost of $29,300. In 1965, the north and south jetties were extended seaward 1,225 and 1300 ft, respectively. The work required a total of 119,000 tons of stone and cost $594,600 ($0 today). The extensions are parallel to one another, spaced 425 ft apart, and terminate at a depth of eight feet below the low-water mark. Their height above low water ranges from 13 ft on their seaward ends to 17 ft (north jetty) and 16 ft (south jetty) at their landward ends. Their flat crowns are 7 ft wide at the seaward end and 5 ft wide at the landward end.
