The Dandenong Creek (Aboriginal Bunwurrung: Narra Narrawong or Dandinnong) is an urban creek of the Port Phillip catchment, in the eastern and south-eastern Greater Melbourne region of the Australian east coast state of Victoria. Its headwaters are in the Dandenong Ranges near Olinda, sourced by a series of springs and small runoff streams within the Dandenong Ranges National Park.

The creek descends approximately over its course of before joining the Eumemmerring Creek to form the Patterson River (of which it can be considered the de facto main stem) and eventually draining into the Beaumaris Bay. Together with its distributary Mordialloc Creek and the culvert-linked Kananook Creek and Elster Creek, the so-called "Dandenong Catchment" has an overall catchment of approximately .Dandenong Creek Snapshot, Melbourne Water 2017

History The traditional custodians of the land surrounding what is now known as the Dandenong Creek were the indigenous Bunurong people of the Kulin nation who referred to the creek as Narra Narrawong; while others gave the creek the name Dandenong, sometimes spelled as Dand-y-non or Tanjenong by early settlers, believed to mean "high" or "lofty". The first European to see the creek near its source was in 1839 and is believed to be Daniel Bunce, a botanist.

Ecology

The series of open space reserves along the Dandenong Creek and its tributaries provide important habitat for many urban wildlife in the outer eastern/southeastern suburbs. The creek is also the home of one of the largest remaining populations of Yarra Gum, and a series of linear parks, nature reserves and wetlands are located along it. A bike path known as the Dandenong Creek Trail runs alongside for a significant distance.

The Dandenong Creek catchment is the westernmost native range of eastern dwarf galaxias (Galaxiella pusilla), which is endangered due to habitat loss, riparian degradation, the extirpation of commensal Geocharax crayfish (whose burrows are utilized by G. pusilla for aestivation during drought), and predation/competition from invasive species such as the redfin perch, brown trout and eastern mosquitofish (which both feeds on eggs of G. pusilla and territorially attacks them via fin-nipping).

The health of the creek in these urban areas ranges from moderate to very poor and has been the focus of a number of clean-up campaigns in recent years. An industrial wastewater stream known as Old Joes Creek flows into Dandenong Creek, with its confluence in . This drain runs underground for much of its course, running in a westerly direction and servicing several industrial estates in the catchment of Dandenong Creek. The tributary is commonly contaminated with plastic litterings and heavy metals, and authorities have made several attempts to prevent pollution which spreads downstream into Dandenong Creek.

Upper Dandenong Creek The Upper Dandenong starts at the Olinda town center and first flows westwards between Mount Dandenong and The Basin, picking up its first significant tributary, the Dobson Creek, near a retarding basin just west of the junction among The Basin, Kilsyth, Kilsyth South and Boronia. It continues further west as the boundary between several adjacent suburbs, picking up Little Bungalook and Tarralla-Bungalook Creek before turning southwards at the junction between Ringwood, Vermont and Wantirna, roughly where EastLink crosses.

Dobsons Creek (left) — headwaters in Sassafras, confluence in northern The Basin (near Liverpool Road Retarding Basin) Old Joes Creek (left) — headwaters in The Basin, confluence in Bayswater (near Marie Wallace Park) Old Joes Creek (No. 5320) is a minor tributary of Dandenong Creek. The name refers to Joseph Gadd who lived with his family on Old Joes Creek. It begins as an open watercourse in the Dandenong Ranges National Park, in the northwestern fringes of Tremont, and continues in underground pipes below The Basin and Boronia before coming out at the Old Joes Creek Retarding Basin. From here, it flows underground below an industrial area in Bayswater before reaching Marie Wallace Park, where it joins Dandenong Creek.

Middle Dandenong Creek The Middle Dandenong starts at the mouth of the small Heatherdale Creek just west of EastLink, and then flows meanderingly to the south, joined by the Blind Creek (near Jells Park). It then crosses over to the east side of the EastLink, joined by the Corhanwarrabul Creek (at the Tirhatuan Wetlands), and then courses southeast towards the western edge of the Churchill National Park, crossing the namesaked Dandenong Valley Highway (Stud Road) in the process. After draining a series of greenspace reserves known as the Dandenong Valley Parklands, the creek reaches the Dandenong Police Paddocks Reserve, in Endeavour Hills and turns more southwardly again as the boundary between Dandenong North and Endeavour Hills. The riparian zones, retention ponds and retarding grasslands in associated runoff catchment surrounding the tri-suburban junction between Dandenong North, Dandenong and Doveton are known as the Dandenong Wetlands, which include a section of Heatherton Road just west of Monash Freeway that functions as a floodway. The creek then continues further south as the northern half of the boundary between Dandenong and Doveton.

Tributaries

Heatherdale Creek (right bank) — headwaters in southwestern Ringwood, confluence in eastern Vermont Heatherdale Creek (Drain No. 5230) is a minor tributary of Dandenong Creek. It has several tributaries of its own, which collect urban runoff from northeastern Vermont, southwestern Ringwood and southeastern Mitcham. It flows mostly underground, emerging briefly at the Heatherdale Retarding Basin before continuing below Heatherdale Road and exiting just north of Canterbury Road. It then travels in a concrete channel passed the Heatherdale Wetlands, where it joins Dandenong Creek. Purches Street Drain Vermont East Drain (right bank) – headwaters in northeastern Vermont South, confluence in eastern Vermont South The Vermont East Drain (No. 5237) is a minor tributary of Dandenong Creek. It was proclaimed in 1973 and diverted underground as part of the Vermont East Drainage Scheme, which provided outfall drainage for new residential estates. Koomba Road Drain (left bank) – headwaters in Wantirna, confluence in Wantirna South Vermont South Drain (right bank) – headwaters in southwestern Vermont and eastern Forest Hill, confluence in Vermont South The Vermont South Drain (No. 5240) is a minor tributary of Dandenong Creek. It was gazetted in 1970 and hastily diverted underground as part of the Vermont South Drainage Scheme, which rectified flooding caused by new housing projects in the area.

It formally begins at the Healesville Freeway Reserve in Vermont, intaking flow from the Bellara Street Drain (No. 5246) before continuing below Felgate Parade to the Bellbird Dell Reserve, where it is joined by the Vermont Drain (No. 5244).

It then runs below Terrara Park and Great Western Drive before joining the Burwood Highway Drain (No. 5241), joining Dandenong Creek just north of Burwood Highway.

The outlet to Dandenong Creek is located in the Bushy Park Wetlands. Weeden Drive Drain Highbury Road Drain Lascelles Drive Drain Nunawading Outfall Drain (right bank) – headwaters in Forest Hill, confluence in Glen Waverley The Nunawading Outfall Drain (No. 5211) was proclaimed in 1970. Its largest tributary is the East Burwood Drain (No. 5214), which begins near the Healesville Freeway Reserve in Forest Hill and continues below Stanley Road to Dalroy Crescent Reserve, where it is joined by the Channel 0 Drain. It then continues below Vermont South and Glen Waverley, and the Camelot Drive Drain (No.5213) joins it below Capital Reserve. It is joined just downstream by the Larpent Street Drain (No. 5212), after which it becomes the Nunawading Outfall Drain. This is then briefly joined by the Gallaghers Road Drain (No. 5211) and the Excalibur Avenue Drain (No.5216) before reaching Dandenong Creek at Shepherds Bush.

Lower Dandenong Dreek The Lower Dandenong starts just upstream of the Clow Street bridge in Dandenong East, where the creek becomes concrete-lined throughout almost its entire course within Dandenong. It first turns southwest at Dandenong Park, looping shortly northwest before crossing Princes Highway and the Pakenham/Cranbourne railway line, then continues further westwards south of the Dandenong town center until it picks up the Mile Creek (its last de jure tributary) about upstream of the Dandenong Bypass bridge.
