The Cooks River, a semi-mature tide dominated drowned valley estuary, is a tributary of Botany Bay, located in south-eastern Sydney, New South Wales, Australia.
The course of the 23 kilometres (14 mi) long urban waterway has been altered to accommodate various developments along its shore. It serves as part of a stormwater system for the 100 square kilometres (39 sq mi) of its watershed, and many of the original streams running into it have been turned into concrete lined channels. The tidal sections support significant areas of mangroves, bird, and fish life, and are used for recreational activities.
The river begins at Graf Park, Yagoona, then flows in a roughly north-easterly direction to Chullora. It reaches its northernmost point at Strathfield, where it leads into a concrete open canal, no more than one metre wide and thirty centimetres deep. It then heads towards the south-east. Where Cooks River runs through Strathfield Golf Course, the concrete lining has been partly removed. Here the plants have returned and have created an environment where the water is filtered and runs clean, and where wildlife has returned. One section here is called the Chain of Ponds.
At Belfield it joins with the Cox Creek Channel and flows in an easterly direction. The canal widens and deepens as it picks up stormwater from surrounding suburbs, such as Campsie and becomes influenced by tidal action.
At Canterbury, it is joined by Cup and Saucer Creek. Industrial areas line the Cooks River at Canterbury. In the past, factories discharged their waste directly into the water.
