The Pemigewasset River ( ˌpɛmɨdʒəˈwɑsɨt ) is the right source river of the Merrimack River in the US state of New Hampshire .
The 105 km long river drains an area of approximately 2645 km². The name "Pemigewasset" comes from the Abenaki language . The word bemijijoasek [bəmidzidzoasək] means: "side where the flow takes place".
geography
The Pemigewasset rises in Franconia Notch State Park in Franconia and flowing shortly after the profiles Lake . It flows south through the White Mountains and connects in Franklin with the Winnipesaukee River to the Merrimack River .
The Interstate 93 extends between Franconia Notch and New Hampton parallel to the river. On its course, the Pemigewasset River passes Lincoln , North Woodstock, Woodstock , Thornton , Campton , Plymouth , Ashland , Bridgewater , Bristol , New Hampton, Hill , Sanbornton and Franklin.
Along the river are several waterfalls in Franconia Notch, such as The Basin , in North Woodstock and north of Plymouth ( Livermore Falls ). The remainder of the northern part of the river from Lincoln to Ashland is an interwoven river that flows over stone steps, attracting boaters and anglers.
Below Ashland, the river to the eight-kilometer-long Ayers Island Reservoir is dammed up to generate electricity using hydropower . Below the dam there is a short section of white water before the river reaches the slower flowing water above the Franklin Falls flood retention basin . Franklin Falls Dam , built in 1943, is primarily used for flood protection .
Before the river joins the Winnipesaukee River in the center of Franklin, it drives a hydroelectric power plant again.
The catchment area of the Pemigewasset River consists of more than 1700 km of watercourses and 69 km² of lake area, including the artificially created reservoirs. It contributes about 20% to the entire catchment area of the Merrimack River.
