During the 19th century and early 20th century, the river's surface was periodically choked by large swathes of the noxious weed known as water hyacinth. To this end, maintenance dredging is carried out between Fisherman Island and the Hamilton Reach of the Brisbane River and within the channels of Moreton Bay (6). 3b). “During that extreme flood event in 2011, the amount of sediment flowing out of the Lockyer was enough to fill a line of dump trucks stretching from here to Adelaide and back,” he said. Despite the concerns, the outlook is not all gloom: some fish species are back and new mangroves and seagrass beds have been found. Dr Maxwell said nitrogen and phosphorus had been increasing since 2005 and now exceeded the Queensland government’s gazetted water quality guidelines. * Note: Price ex plant , plus GST, call for quote on large quantities.
