In Lake Erie, water exchange occurs among a small, shallow western basin, a larger, deeper central basin, and an eastern basin that includes the deepest point in the lake (Sly ). Water enters. Thus, the eastern and central basins of the modern lake are much deeper than the western basin, which averages only 25 feet ( m) deep and is rich in nutrients and fish. Lake Erie is the shallowest of the Great Lakes because the ice was relatively thin and lacked erosion power when it reached that far south, according to one nates: 42°12′N 81°12′W / °N .

The Great Lakes (French: les Grands Lacs), or the Great Lakes of North America, are a series of interconnected freshwater lakes in the upper mid-east part of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence comprise Lakes Superior, Michigan, Huron, Erie, and Ontario.

Army Figure 11 — Annual mean phytoplankton biomass in Lake Erie’s western and central basins, ‐ ‐ bars are arithmetic means, whereas those from ‐ are geometric means. Typically Lake Erie’s central and eastern basins undergo thermal. The communities of phytoplankton vary greatly among the sub-basins of Lake Erie and also between its nearshore and offshore waters. The eastern and central basins are relatively deep and unproductive, while the shallower western basin is more productive. In all three basins, however, shallow nearshore habitat is more productive than offshore : Bill Freedman. Diet information was collected from age-1 and older walleyes caught in both fall trawls and gill nets in the western, west-central, and central basins of Lake Erie in Consistent with previous years, there is an apparent shift in walleye diets from clupeids in the western basin to clupeids/shiners in the west-central basin to smelt/shiners.
Today, annual Microcystis blooms occur in all basins of Lake Erie and within many of its embayments, although large scale surface blooms are generally confined to the western and west-central basins of the Lake and embayments near Sandusky (OH), Presque Isle (PA) and Rondeau Provincial Park (ON). The duration of these blooms has expanded during Cited by: Lake Erie is the shallowest and warmest of the Great Lakes, with the shortest retention time (~ years, Fuller et al., ), and is typically divided into three basins—Western, Central, and Eastern 17 study sites along the Ohio shoreline were located only in the Western and the Central Basins ().The Western Basin has an average depth of m, and is acutely suffering from Author: Václava Hazuková, Jeffrey R. Johansen, Jeffrey R. Johansen, Gerald V. Sgro. Benthic and pelagic secondary production were measured at nearshore and offshore sites in the western, west-central, and eastern basins of Lake Erie in to determine the relative importance of benthic and pelagic foodwebs to the fish community after dreissenid colonization. Benthic biomass increased greatly between and because of the presence of dreissenids, and >90% of benthic Cited by: NOAA Technical Memorandum ERL GLERL, Great Lakes Environmental Research Laboratory, Ann Arbor, MI (PB/XAB) pp. (). A year set of lake levels and flows has been developed that reflects a consistent hydraulic regime in the Great Lakes-St. Lawrence River system.
