Yamaska River

Catchment area of ​​the Rivière Yamaska

The Rivière Yamaska ​​is a right tributary of the St. Lawrence River in the south of the Canadian province of Quebec.

The 154 km long river drains an area of 4843 km ². Its name comes from the language of the Abenaki. It can be translated as " where the rushes grow " and refers to the march at the mouth.

The source of the river is located in Lac Brome, a lake in the foothills of the Appalachian Mountains. The Yamaska ​​initially flows westward. Shortly after Farnham he describes a striking 90 -degree bend and then flows north through the flat plain of the St. Lawrence Valley. Near the village of Ville Pierre River eventually flows into the Lac Saint- Pierre, which forms part of the current. One kilometer northeast of the mouth of the Yamaska ​​is that of the Rivière Saint -François.

The catchment area of ​​the Yamaska ​​is one of the most intensively farmed regions of the province, which is why the burden of fertilizer is higher than average.
