The Baker River, or Asquamchumauke, is a 36.4-mile (58.6 km) long (58.6 km) river in the White Mountains region of New Hampshire, the United States. It rises on the south side of Mount Moosilauke and runs south and east to empty into the Pemigewasset River in Plymouth. The river traverses the towns of Warren, Wentworth, and Rumney. It is part of the Merrimack River watershed.
The Baker River's name recalls Lt. Thomas Baker (1682–1753), whose company of 34 scouts from Northampton, Massachusetts passed down the river's valley in 1712 and destroyed a Pemigewasset Indian village. It was along this river on April 28, 1752 that John Stark and Amos Eastman were captured by Abenaki warriors and taken to Saint-François-du-Lac, Quebec, near Montreal. John Stark's brother William Stark escaped, and David Stinson was killed during the ambush.
On the 1835 Thomas Bradford map of New Hampshire, the river is shown as "Bakers" River, originating on "Mooshillock Mtn.
There is a large fish hatchery on the Baker River in the town of Warren. This river, winding though the Baker River Valley, has several launch sites along Route 25. Canoeing is generally a scenic tour at medium water level with access in Wentworth and Rumney. Brook Trout and Rainbow Trout are available along the Baker's 4 mile stretch within the valley. The river provides a habitat for coldwater fisheries, including trout and salmon. Fish are important to the Baker River watershed since sport fishing attracts many residents and visitors to the area, and is a large contributor to the economy. The river consists of numerous gravel bars, rocks, and boulders, shoreline brush, weedlines, coves, inlets and submerged riprap.
