Petticoat Creek
Petticoat Creek is a watercourse in Pickering, Ontario and Toronto, Ontario. Its watershed covers 27 square kilometres (10 sq mi), and the cumulative length of all its branches is 49 kilometres (30 mi). Land use in the watershed consists of 52% agricultural, 27% protected greenspace and 21% urban. Municipalities within the watershed include Pickering, Markham and Toronto.
According to the Toronto Region Conservation Authority the ″Petticoat Creek watershed is dominated by the South Slope physiographic region, a smooth, faintly drumlinized till plain.″ Because the creek is not long enough for its headwaters to lie within the groundwater rich Oak Ridges Moraine, waterflow on the upper reaches is intermittent and dependent on precipitation. Lower reaches, below the ancient shoreline of glacial Lake Iroquois, is more consistent.
The Petticoat Creek Conservation Area is located in the watershed and managed by the Toronto and Region Conservation Authority after the Petticoat Creek Conservation Authority was absorbed in the TRCA. It is located at the mouth of the creek at Lake Ontario.
