Saint-Augustin River

The Saint-Augustin River has its source in the mountains of Labrador, and winds south to Saint-Augustin Bay.{{sfn|Rivière Saint-Augustin, Commission}}

{{convert|109|km}} of the {{convert|238|km}} main channel is in Labrador.{{sfn|Hydrology of the Transboundary Rivers|p=5}}

Major tributaries include Matse River, Michaels River, Rivière à la Mouche and Rivière Saint-Augustin Nord-Ouest.{{sfn|Hydrology of the Transboundary Rivers|p=62}}

The Saint-Augustin Northwest River joins the Saint-Augustin River {{convert|1|km}} upstream from its mouth.{{sfn|Rivière Saint-Augustin, Commission}}

The mouth of the river is in the municipality of Saint-Augustin in Le Golfe-du-Saint-Laurent Regional County Municipality.{{sfn|Rivière Saint-Augustin, Ressources naturelles}}

At the mouth of the river the Pakuashipi ("sand river") Innu community is on the west shore and the village of Saint-Augustine is spread over hills on the east shore.

The two communities are accessible only by sea or air.{{sfn|Traverse de la rivière Saint-Augustin}}

A barge is used to carry goods across the river, and a hovercraft takes passengers.

A new barge was due to be delivered in 2020.{{sfn|Bordeleau|2019}}

The free passenger ferry takes five minutes to make the {{convert|0.9|km}} crossing, but only runs between April and December.

After the river has frozen over it can be crossed by snowmobile over the "Route Blanche" ice bridge.{{sfn|Traverse de la rivière Saint-Augustin}}

Louis Jolliet (1645–1700) called the river Pegouasiou, and Jean-Baptiste-Louis Franquelin (1650–1712) called it Pegouachiou, meaning "deceptive river", probably given that name by the indigenous people because of it is shallow and the sandbars in its mouth are unstable.

The name Saint-Augustin was given to the river in the 18th century, and then to the village on the east shore of its mouth.{{sfn|Rivière Saint-Augustin, Commission}}

The name may refer to Augustin d'Hippone, a priest, or to Augustin le Gardeur de Courtemanche (1663–1717), first concessionaire of a strip of land that extended "from the river called Kegaska to that named Kesesakion".{{sfn|Municipalité de Saint-Augustin (Côte-Nord)}}

The headwaters of the main channel form at an elevation of {{convert|570|m}}.

The maximum elevation in the watershed in {{convert|592|m}}, and the average elevation is {{convert|342|m}}.{{sfn|Hydrology of the Transboundary Rivers|p=7}}

The river drops about {{convert|460|m}} in the Labrador section, then drops only {{convert|100|m}} in the last {{convert|120|km}}.{{sfn|Hydrology of the Transboundary Rivers|p=61}}

A hydrometric station recorded flows from 1967 to 1982.

Mean annual flows ranged from {{convert|146|to|207|m3/s}}.

Minimum flow in the winter was {{convert|10.8|m3/s}} and maximum flow in May/June was {{convert|2,040|m3/s}}.{{sfn|Hydrology of the Transboundary Rivers|p=61}}

A map of the ecological regions of Quebec shows the river in sub-regions 6o-T, 6n-T and 6m-S of the east spruce/moss subdomain.{{sfn|Saucier|Robitaille|Grondin|Bergeron|2011}}

Land cover in the watershed is 74.3% forest, 12.9% non-forest vegetation, 3.1% barren, 1.3% wetlands and 8% water.{{sfn|Hydrology of the Transboundary Rivers|p=9}}

Average daily mean temperature is {{convert|0|to|1.2|C}}, ranging from {{convert|-16.5|to|-12.8|C}} in January to {{convert|13.9|to|15.2|C}} in July.{{sfn|Hydrology of the Transboundary Rivers|p=13}}

Annual total precipitation is {{convert|1,005.4|-|1,122.4|mm}}.{{sfn|Hydrology of the Transboundary Rivers|p=18}}

From the river mouth it is possible to see a wide variety of sea birds as well as seals and whales.{{sfn|Traverse de la rivière Saint-Augustin}}
