Carrum Carrum Swamp
The Carrum Carrum Swamp was a historic coastal wetland encompassing 52 km2 (20 sq mi) with a catchment area of 735 km2 (284 sq mi) that . It had four drainage outlets into the Port Phillip Bay, including the modern-day Kananook Creek/Eel Race Drain, Patterson River and Mordialloc Creek (a distributary of the Patterson River's upper section, the Dandenong Creek). Explorer William Hovell discovered "a very extensive fresh water marsh, from 12 to 15 miles long and 11/2 to 6 broad, and only separated from Port Phillip by a narrow ridge or bank of sand not more than from two hundred to three hundred yards wide." A painting titled "Lagoon in the Carrum Carrum Swamp – evening 1872" by James W Curtis is held at the National Gallery of Australia.
Due to modern land developments and drainage measures only remnants of the swamp remain, such as the Edithvale-Seaford Wetlands.
