| Notes |
| | Much of the data in these reports and graphs is from gauges operated by: Meteorological Service of Canada (Environment Canada), Ontario Ministry of Natural Resources, United States Geological Survey and US Army Corps of Engineers. Some of the data is provided by ACH LP, Boise Cascade, Manitoba Hydro and Ontario Power Generation. Some data is obtained from volunteer observers. |
| | These reports and graphs are all provided in Adobe Acrobat "pdf" format. Adobe Acrobat Reader (more recently called just "Adobe Reader") is required to view them. If you do not have Acrobat Reader, it is available free from Adobe Software |  |

| | In some browsers you may have to select the desired report or graph with the right mouse button to save the file on your computer rather than view it online ("Save Target As..." in Internet Explorer; "Save Link As..." in other browsers). |
| | When using Acrobat 6.0, set magnification to 118% or greater to make grids on the graphs visible. |
