The data in these reports and graphs is from a variety of sources, including the following: Water Survey Canada (water level and flow gauges in Ontario and Manitoba), Meteorological Service of Canada (precipitation and temperature data); Ontario Ministry of Natural Resources and Forestry (precipitation data); United States Geological Survey (water levels and flows in Minnesota); US Army Corps of Engineers (water levels in Minnesota); H2O Power LP (water level and flow data from dams in Ontario), PCA (water level and flow data from dam in International Falls), Manitoba Hydro (water level and flow data from dams in Manitoba) and Ontario Power Generation (water level and flow data from dams in Ontario); volunteers (precipitation data in Ontario and Minnesota). Inflow for the major lakes is computed by the LWCB, as are all statistics. |
