Hinchinbrook Brook

The Hinchinbrook Brook (French: Rivière Hinchinbrooke) is a tributary of the Châteauguay River, flowing on the south bank of the Saint Lawrence River, in:
 * the municipality of Hinchinbrooke, in the administrative region of Montérégie, in the province of Quebec, in Canada;
 * Franklin County, in New York State, in United States.

The lower part of the course of this river is accessible by Brook Road (east-west) and the Herdman Customs climb (north-south). The American part of the course of the river is mainly accessible by the River Street which leads south to the town of Chateaugay.

The surface of the Hinchinbrook Brook (except the rapids areas) is generally frozen from mid-December to the end of March; however, safe circulation on the ice is generally done from the end of December to the beginning of March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
