The Becaguimec Stream (/ˌbɛkəˈɡwɪmɛk/)[1] is a minor tributary of the Saint John River in the Canadian Province of New Brunswick.
The South Branch flows from Becaguimec Lake 13 kilometres southeast of the community of Cloverdale.
The stream is slow-paced and meandering between the forks and Mill Brook near Ashland, not infrequently changing course because of floods.
The Becaguimec enters the Saint John River at the town of Hartland, the site of the world's longest covered bridge.
The Wolastoqiyik (Maliseet) people named the river for the bountiful salmon pool which lay at the mouth of the stream.
One of the earliest records of permanent settlement at this site indicates that in 1790 a Wolastoqiyik man by the name of Governor Toma was found "tilling his cornfield" at the mouth of the Becaguimec.
A a concrete road bridge (New Brunswick Highway 105) crosses the stream at Hartland paralleled by a Canadian Pacific Railway trestle (now part of The Great Trail).
The mill was then leased to Alexander Shaw in 1887 who introduced a steam engine to the operation the following year.
