HYDAT Database - Canada

Coordinate system: 4269 - "NAD83"


HYDAT is a water database containing data on daily and monthly means of flow, water levels and sediment concentrations (for sediment sites).

Data include: daily, monthly, and/or instantaneous data for stream flow, water levels, sediment concentration, sediment particle size, and sediment load for over 2500 active stations and some 5500 discontinued sites across Canada.

An MS Access database stores a series of watershed characteristics. These characteristics include;

  • annual statistics
  • annual instant peaks
  • daily flows
  • daily water levels
  • sediment types
  • sediment loads
  • stations
Most watersheds and gauges are characterized but could be incomplete.
