The Upper Thames River Conservation Authority monitors several stream flow and meteorological stations throughout the watershed as part of its Flood Control Program. These stations measure parameters such as water level, rainfall and air temperature in real-time, recording values on at least an hourly basis. This information is collected from remote sites via telephone modem on a daily basis during low flow periods and more frequently during floods, and then stored.

Water levels are converted to flows, which are measured in cubic metres/second (CMS).

• 1 cubic metre (1,000 litres) = 2 bathtubs

• 100 cubic metres = an in-ground swimming pool

We measure stream flow at 23 locations, rainfall at 16 locations and reservoir levels at four locations. Other meteorological parameters, such as air temperature, wind speed and direction and solar radiation, are also measured at some locations. During the winter months, staff conduct manual snow surveys on a bi-weekly schedule to provide information on the state of the snow pack.

The information provided by the monitoring system supports the UTRCA's flood management and low flow response activities, as well as day to day operations of the water control structures such as Fanshawe, Pittock and Wildwood Dams. In recent years, recreational users of the river have also shown an interest in this information.

As flood control is a provincial responsibility, delegated to Conservation Authorities where they exist, much of the funding for this system comes from the Ontario Ministry of Natural Resources. Many of the stream flow stations are operated by the Water Survey Division of Environment Canada. Stream gauge stations are cooperatively managed through a cost-share agreement between the Province of Ontario and the Federal Government, in partnership with the Conservation Authority.
