There are currently over 2000 hydrometric gauging stations in Canada’s
national network. The 59 stations shown on this map represent the
general hydrological conditions across Canada providing information
on the flow-rate at times of water quality sampling, water abstractions
for domestic and industrial use, the formulation of license conditions
for effluent discharge during low flow, the design of bridges and
drainage works, and flood prevention and alleviation during flood
flows.
These are automated stations located on rivers that record water
level, flow velocity or speed and discharge (the volume of water
that passes a given point in one second). The water level data at
these stations are collected and transmitted every three hours.
Current water levels and recent trends observed at these stations
may be viewed graphically by clicking on the Get Info from Map
button above the map and then clicking on one of the stations.
