Hydrology in smaller drainage basins is governed by the degree of urbanization and impermeable, high-runoff surfaces. In the Don River Watershed in the Lake Ontario basin, urbanization of 15 percent of in 1950 is predicted to become 91 percent in 2021. [77] Average annual flows in the Don River have increased by 0.44% per year since the early ...

Highway 407 was designed with aesthetics and environmental concerns in mind, featuring landscaped embankments, 79 storm drainage ponds, and a curb and gutter system. [19] Unlike most Ontario highways, it features concrete pavement as opposed to top-coated asphalt.
Lake Ontario's drainage basin. Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7,340 sq mi, 19,000 km 2), [5] although it exceeds Lake Erie in volume (393 cu mi, 1,640 km 3). It is the 13th largest lake in the world. When its islands are included, the lake's shoreline is 712 miles (1,146 km) long.
