Statement: HYDAT - Online access to historical water levels, streamflow and sediment data of Canada

Abstract: On-line access to information on historical (archived) water levels and streamflow. Using map-based or text-based searches, users can locate over 1200 hydrometric stations measuring water levels and view hydrographs of historical waer level and streamflow data. Alternatively, users can use a separate tool to select and access historical data from over 2500 active stations and 5500 discontinued stations. In addition, a third tool allows users to generate historical water level and/or streamflow statistics for any of these (more than) 8000 stations.
