The 'Kennebecasis River', pronounced ''ke-ne-buh-KAY-sis'', is located in southern
New Brunswick,
Canada. It runs for approximately 97
kilometres, draining an area in the ''Caledonia Highlands'' (an extension of the
Appalachian Mountains), inland from the
Bay of Fundy.
The river's source is in the foothills of
Albert County, near the rural community of
Goshen. It runs southwest through the community of
Penobsquis; several tributaries join the river in the town of
Sussex several kilometres further west.
Between Sussex and the river's junction with the
Saint John River at
Millidgeville (part of
Saint John), the Kennebecasis River runs through a well-defined river valley which has become one of the primary land transportation routes in the southern part of the province, hosting the
Route 1 expressway and the
CN railway line to the port of Saint John.
The upper 2/3 of the Kennebecasis River passes through pastoral rural countryside consisting of Acadian mixed forest and various agricultural areas, notably the
dairy farms around Sussex. Southwest of Sussex, the river becomes increasingly larger as it passes the communities of
Norton and
Hampton, before it empties into a
delta-like area called the 'Hampton Marsh'. West of Hampton, the Kennebecasis flows in a broad
fjord-like glacial valley which defines the southern side of the Kingston Peninsula. At its junction with the Saint John River, the Kennebecasis River helps to form 'Grand Bay'.
Several large islands can be found in the river, such as 'Kennebecasis Island' just off-shore from
Summerville on the Kingston Peninsula, and uninhabited 'Long Island', located near
Rothesay.
Lower Kennebecasis River valley

The communities of
Nauwigewauk,
Quispamsis and
Rothesay become increasingly urban as the river approaches its junction with the Saint John River. The lower Kennebecasis River valley is largely a suburban/exurban region for
Saint John. The area is outside the summer '
fog belt' for the
Bay of Fundy and enjoys more sunshine year-round than Saint John. It is also substantially colder in winter than the Bay of Fundy-climate controlled city proper.
"The Valley" or "KV", as the lower Kennebecasis River valley is called by locals, has experienced dramatic growth over the past several decades, largely owing to the development of Route 1 through the area in the 1960s. Once a minor dormitory suburb of the Saint John area, the towns of Rothesay and Quispamsis constitute a moderately-sized population centre with some commercial development. Saint John, by contrast, has suffered from an erosion of its tax and commercial bases as population and businesses have migrated away from the urban core.
The Kingston Peninsula is isolated from suburban sprawl by the Kennebecasis River which is crossed only by two ferry services at Gondola Point-Reeds Point and Millidgeville (Turners Flats)-Summerville. A third ferry service connects Summerville to Kennebecasis Island.
The Kennebecasis River valley communities have rich histories, having come to prominence during the late
1800s following construction of the
European and North American Railway through the area, which allowed for easier travel between Saint John and Moncton. Over the ensuing decades, the lower Kennebecasis River valley became a summer vacation destination for wealthy Maritimers, Americans and central Canadians. It is also a popular
cruising destination for recreational boating as a result of its connection with the navigable portions of the Saint John River.
