The Mississippi Valley Conservation Authority (MVCA) monitors stream flow, meteorological conditions, operational conditions at the dams and water quality. The information is collected and transmitted from each station to the MVCA's office in Carleton Place, Ontario.
Data posted to this web site is provisional data that has not been reviewed or edited and is subject to change. This data is not citable until reviewed and approved by the MVCA or our partners.
A number of factors will influence the accuracy of real-time water level and flow data including:
- backwater from ice, weeds or debris,
- malfunctioning equipment and/or routine maintenance of equipment which may cause data spikes, and
- sediment accumulation which may lead to plugged intakes.
A number of factors will influence the accuracy of real-time rain fall data including:
- funnels and instruments which may become fouled with debris or insects,
- the tipping bucket mechanism may malfunction, and
- the tipping bucket rain gauge may not properly record precipitation during freezing weather conditions.
A number of factors will influence the accuracy of real-time water quality data including:
- water quality probes may become fouled with sediment or debris, and
- malfunctioning equipment and/or routine maintenance of equipment which may cause data spikes.
River levels and flows can change rapidly in response to water entering the river as a result of rainfall or snowmelt, or changes in discharge from the major reservoirs operated by the MVCA.
Users of the MVCA's real-time data are cautioned to consider the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business.
