Great Lakes Advanced Hydrologic Prediction System (AHPS) Products (Experimental)(Based on choosing scenarios from 1948-1999) On this page are links to plots for monthly values of inflow, outflow, total supply, mean lake level and other hydrology and meteorology variables for each of the Great Lakes and Lake St. Clair. Products include 18-month hindcast simulations and 9-month outlooks. Simply click on a lake in the ImageMap below to access the products. These products are updated daily.
Lake Superior | Lake Michigan | Lake Huron | Georgian Bay | Lake St. Clair | Lake Erie | Lake Ontario These forecast values are based on our best estimate of current conditions (computed from available meteorological data), climatological forecasts and physical process models. They represent our best estimate of what will occur given an accurate climatological forecast. These forecasts are probabilistic, and the values are non-exceedance quantiles. That is, for example, the 5% value is the value for which there is a 5% probability of the actual value being lower. Thus, the range between the 5% and 95% values is the range in which we expect the actual value to fall 90% of the time. More information on the background and methods of generating an outlook is also provided.
