  • Peel-Harvey Estuary - Lakes Need Water
    was an environmental mess The system is said to be Australia s largest inland waterway which also featured sediments high in organic matter similar to the Lower Lakes and Coorong The Dawesville Channel cut in 1994 was the redeeming feature here by providing further access from the Indian Ocean Moving 180 000 cubic metres of acid sulphide soils while keeping it below water was also a major factor in achieving

  • Locks and Weirs of the River Murray - Lakes Need Water
    lock 10 is controlled by NSW In total there are 26 man made locks weirs barrages on the River Murray Lock One at Blanchetown is 274 km s from the Goolwa barrages The distance between each of the other locks and weirs range from 29 to 88 km s apart Below is a map with the locks and weirs located Between the red location pins there is no weir or lock that can be used to control water levels From the map below it is very apparent that the river is narrow until it gets to Wellington where it meets Lake Alexandrina Lake Alexandrina and Lake Albert require about 2000 GL to fill Where as in other parts of the river much smaller quantities of freshwater are required to keep the river levels elevated One more weir near Wellington would make this 274 km stretch of the Lower River Murray more manageable This 274km stretch of water includes two very different environments a river system from Blanchetown to Wellington and the Lower Lakes system A Lower Lakes system which could be restored to estuarine and allowed to become tidal again One more weir near Wellington would prevent seawater from travelling

  • Re-vegetation Photos - Lakes Need Water
    Australia This is a picture of non vegetation of acid soils This photo from November 2009 is at the entrance of Dunn s Lagoon The previous four months had been wet hence the boggy soil and by November it is expected that the warmer weather and fresh rainwater would have helped natural vegetation to become established However this photo on the left clearly shows that although the sandy areas on both sides are vegetated the marginal plants are looking decidedly sick as is the one and only only plant in the centre of the photo Click to enlarge the photos Have a look at the photo on the right taken May 2010 of the same site now that the water has risen about 0 4m This is all natural not planted as the plants are the same as those that are rather sick in the photo above from November 2009 According to CLLMM The plant species in the photo is commonly known as Yellow Button or Waterbuttons Its scientific name is Cotula coronopifolia This is a native species and generally grows at the edge of swamps and in marshy ground What some of our Lake Needs Water members are noticing
