Streamflows

The RVCA real-time streamflow network is made up of five regional stations operated by Water Survey Canada (WSC). Streamflow data is computed on an hourly basis and calculated in cubic meters per second. Statistics have been generated from a 30-yr period of record and represent the typical seasonal flows observed over the historic record.

NOTE: All data provided through the RVCA real-time network is considered PROVISIONAL and has not been reviewed or verified. Please see our data disclaimer below for more details.

Real-time streamflow conditions can be reviewed through our interactive map or from the chart links below:

Water Levels - Real-time

The RVCA real-time water level network is comprised of data from a variety of sources, including the RVCA, Parks Canada (PC) and Water Survey Canada (WSC). Water level data is measured on an hourly basis and provided with geodetic reference (meters above sea level). When applicable, flood thresholds, operational objectives and historic levels have been incorporated into the charting tools.

Water Levels - Periodic

The RVCA periodic water level data is associated with a network of water level sensors on lakes and rivers that are actively logging, but are not configured to transmit live data. Data is accessed through seasonal field visits and manual downloads.

Snowpack

The RVCA monitors the accumulated snowpack at six sites across the watershed. Snow measurements are taken approximately every 2 weeks to quantify the amount of water in storage on the land. This information is used as a component of our flood forecasting and warning program.

Weather Stations

The RVCA weather station network is comprised of 11 all-season weather monitoring systems deployed across the watershed. These weather stations measure the air temperature, dew point, relative humidity, air pressure, solar radiation, average wind speed and precipitation at hourly intervals in near real-time. A summary precipitation report is available below which includes the cumulative precipitation totals (mm) over the past 1, 6, 24, 72 hours and 7 days.
