Streamflow and water level data are used to monitor flood and drought events. They are also used to monitor water supply for lake operation and navigation. This information is used to determine flood risk, support land use planning, assess fish habitat and for water quality analyses of contaminant loading.
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.

Streamflow Summary Chart:
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.

Parks Canada Water Management InfoNet:
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.

Periodic Water Level Graphs:
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.

Snow Measurements:
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.
