Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass through the borough. The lane dates back to Roman times and runs between the Quaggy and Ravensbourne rivers. A new bridge over the Quaggy River was built in 2003. The name probably originated from the words quagmire and quaggy. The Quaggy River flows northward through Chinbrook Meadows. The Quaggy also has several small and named tributaries of its own. The Quaggy receives additional water from Mottingham Tarn and feeds the wetlands in Sutclife Park. Since 1991, Quaggy Waterways Action Group (QWAG) have spent millions maintaining the River Ravensbourne. The Quaggy runs through and joins Mottingham playing fields (colloquially known as 'Foxes'). Those quaggy terrains transformed at Lakua, which now doubles the inhabitants that Vitoria had.
