ThePamet River is a 4.2-mile-long (6.8 km)[1] river inTruro, Massachusetts onCape Cod. It is named for thePaomet tribe.

The river is primarilysalt marsh, flows west nearly all the way across Cape Cod from its eastern beaches, and empties intoCape Cod Bay. It lies a few miles south of theLittle Pamet River.

The upper Pamet River is made up of afreshwater marsh. The marsh occupies the broad floor of the upper Pamet River valley. Originally, 12,000–13,000 years ago, this was the glacial outwash channel that drained water away from the glacier westward, northward and finally eastward into the Atlantic some distance from whereProvincetown now lies. Sea level was then 300 to 400 feet (91 to 122 m) lower than it is today. There was no Cape Cod Bay, andStellwagen Bank and theGrand Banks were hills well above the ocean. The subsequent rise of the Atlantic Ocean, which continues to this day, nearly drowned the outer Cape, including the Pamet, which is now only four miles long, compared to 30 miles (48 km) long thousands of years ago. This upper freshwater marsh dates from the middle 19th century, when, to promote agriculture, the saltwater tides were prevented from entering by means of adike that traverses the valley where Truro Center Road (a former routing ofUS Route 6) now passes. A one-wayclapper valve permitted fresh water to leave at low tide. The result is the meandering, slow-flowing stream that flows from the Atlantic dunes atBallston Beach west to the bay, with low, flat banks that lie just above the water table. The entire valley, fresh and salt, is underlain by a thick mat of peat derived from the original salt marshes. All plant species growing in this upper portion were brought in as seeds, mostly by birds and mammals. All are indigenous, and virtually none is tolerant of seawater.[citation needed]
