Melbourne Water Corporation manages the waterway. The Creek carries excess rainwater from a wide catchment area including most of Frankston and Seaford. Melbourne Water removes snags and rubbish and monitors the water for pollution. Melbourne Water is also responsible for dredging silt deposits at the drain outlets. In addition, the Environment Protection Authority investigates reported pollution.
Littering and rubbish dumping are visible and unsightly pollutants that can prove hazardous for our native fauna and flora. Much of the rubbish in the creek arrives via the stormwater system. Some of this rubbish then find its way into Port Phillip Bay.
A number of litter trapping devices have been installed at storm water outlets in an effort to rectify this problem. Unfortunately, it is a problem best addressed at its source.
Other less visible but equally hazardous pollutants are also transported by way of the storm water system. Urban run-off remains a formidable obstacle to improved water quality in the creek. Oil, petrol, detergents, fertilizers, chemicals; every substance tipped down the sink, washed from the road or hosed from the footpath is likely to end up in our waterways.
The KCA conducts two waterway clean ups per year with the assistance of Melbourne Water.
Fluctuating water flows, cleared banks, water craft use, increased water salinity (and therefore changes in bank vegetation) are contributing factors to the creek bank erosion that has occurred. A number of remedial strategies have been trialled, in particular revegetation.
A speed limit of 8 km operates in order to minimize bank erosion.
Desilting of the creek mouth and drain inlets and outlets is a perennial issue. Desilting is essential to maintain navigability and control flooding.
