waterways
Lake Macquarie is Australia's second largest salt-water lake. It is bound by the Wattagan Mountain Range on the west and the Tasman Sea on the east. The lake can appear with picture perfect waters great for recreational boating, swimming or just to look at, but contains fully functional ecosystems complete with mudflats, salt marshes and saline wetlands. But this is not all the lake is made out to be, over the past years the lake has been attacked by Weeds, Salinity and marine life invasion. There are many areas that are the cause and that are affected by the pollution and not all of the environmental problems are human interaction problems. There are also some natural problems that have arisen.When we think of a waterway we often think of cascading waterfalls bursting with lush vegetation and wildlife. In many areas of the lake Macquarie, waterways remain picturesque parts of the environment, but in others this is not the case.Our Lake drains an area of approximately 605km2 through huge networks of waterways varying in size and texture (example: concrete). Cockle Creek and Dora Creek are the two main waterways in the lake Macquarie area. Dora Creek Drains the west of the lake which is relatively a nat
Water quality is therefore largely dependent on good planning and management of land use in the catchment and around the foreshore. While the council has constructed works, such as wetlands, to control stormwater pollution, there is a need for an on-ground works, which controls the sources of stormwater pollution and community education. NSW FisheriesThe NSW Fisheries are interested in the lake because thousands of fish species come into the lake to breed including many types of turtles. ConclusionThe main interest on the lake is coming from more of a state level because of things like fishing, water sports and tourism and big organizations are investing in Lake Macquarie because they are positive about what is going to happen in the future. LandcareThere are also over 140 landcare groups around the lake cleaning up the lake and making it a beautiful place. Land clearing also makes it easier for unwanted nutrients to access the lake without first going through the natural process of removal of nutrients by plants. This can lead to algae, muddy water and reduced recreational amenity* Erosion and sedimentation of the waterway* A reduction in available habitat for plants and animals which can lead to a lost biodiversity. When an area in urbanized, usually there will be paved and sealed areas. * Increasing nutrient concentrations* Excess bacteria levels* Decreasing clarity of the water* Increased water temperatures at the southern end of the lake. Litter that is left anywhere ends up being blown or washed into waterways and into the lake. This imbalance of nutrients can result in algae blloms. The adopt-a-SQID program hits the community in environmental monitoring, reporting and community education programs. Water Studies have been carried out on the lake since 1954. For example, The dredging of Swansea Channel led to increased wave action and erosion of slats bay over many years. If there is a natural drainage system it should be preserved and the conrete system should not go in.
