The year 2014 at Sydney Olympic Park started off with a rare seasonal event as on 2 and 3 January the Park’s estuarine wetlands experienced King Tides.
It was quite a sight for those bike riding or walking in Bicentennial Park, where water levels rose and temporarily inundated some pathways.
King Tides are a natural phenomenon and occur twice a year: once during summer and again during winter. They are a part of the daily and seasonal tidal cycle and can vary year to year depending on atmospheric, geological, climatic and local conditions.
King Tides have positive benefits as they are essential for the estuarine ecosystems, particularly for some invertebrates, such as tiny crabs that live in the upper marsh areas. The crab life-cycle, especially spawning, is closely tied with tides. In turn, many of the fishes that we eat are dependent on these crab larvae and other smaller fishes.
Other marine life also take advantage of such rare seasonal events to flourish.
Due to the King Tides, Sydney Olympic Park Authority staff has had to adapt its pest mosquito management program as the excessive tidal inundation has caused additional breeding of nuisance mosquitoes. For the most up-to-date mosquito management information visit the Noticeboard on our website.
