There are 15 stations with equipment continuously recording water levels within the Rideau Watershed. Nine of these have rating curves established. The other 6 are used to monitor water level only and are what the operation of the Rideau Canal system of storage reservoirs is based. Data is collected regularly by various agencies including Environment Canada -- Water Survey Division, Rideau Canal Office of Parks Canada and the RVCA. You can click on the stations below or on the map (comming soon) to view the current data in a graphical form (Adobe Reader required).
