The Brock River is a stream on the north bank of the Missisquoi River. The Brock River flows in the municipality of Sutton, in the Brome-Missisquoi Regional County Municipality, in the administrative region of Estrie, in the province of Quebec, in Canada.
Road access to this valley is possible by the Eastman road (attached to the south to the Vallée-Missisquoi road), serving the lower part of this small valley (east side). Forestry is the main activity in this small valley; recreational tourism, second.
The surface of the Brock River is generally frozen from the beginning of December until the end of March; however, safe circulation on the ice is generally done from mid-December to mid-March, except the rapids areas. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
