The Rivière Arnaud ( English Arnaud River ; formerly Payne River ) is a river in the Nunavik region in the Canadian province of Québec .
It has its origin in Lac Payne on the low plateau of the Ungava Peninsula , from where it flows over a series of ice-covered and glaciated lakes to Ungava Bay . Its mean annual discharge is about 15 km³. The river is only ice-free in summer. The rest of the time, it freezes several meters. The length of the river is about 150 km.
The Inuit settlement of Kangirsuk is located at the mouth of the Rivière Arnaud on the north bank of Payne Bay, 13 km inland from the coast of Ungava Bay.
The catchment area of the Rivière Arnaud is predominantly wasteland due to the hostile climate. The average temperature in summer reaches 7 ° C. The permafrost begins at a depth of half a meter. The vegetation consists of low bushes on the lower altitudes, as no trees grow in the catchment area of the Rivière Arnaud. The river's short ice-free time prevents it from being used to generate electricity.
Important tributaries of the Rivière Arnaud are Rivière Lepellé , Rivière Vachon and Rivière Buet from the left, Rivière Hamelin from the right.
The river was originally called the Payne River . In 1968 it was renamed Rivière Arnaud in honor of the clergyman Charles-André Arnaud (1826-1914).
