  • Hovercraft - Lakes Need Water
    surveys The use of the hovercraft was arranged from the beginning of March 2009 by SA Water and then EPA staff to check acid soils and water quality in shallow areas and muddy ground around Clayton Barrages and local feeder rivers A full comprehensive study was then carried out by CSIRO scientists on Lake Albert and Alexandrina to gain more samples of sulphate deposits creating acidic conditions with low water Over 500 kilometers were flown in two weeks This was the most extensive use of a hovercraft for survey in the states history The craft carried survival gear and emergency equipment to ensure repairs to the craft in remote and dangerously muddy areas where the only access is by another craft The speed at which the sample sites could be accessed and tests carried out greatly increased the sample rates to hasten the decision making process on remedial action urgently required Photos from around the Clayton area and Mulgundawa top north east corner of Alexandria show cracked drying mud in which the hovercraft had to stop due to loss of air cushion through the cracks If the cracks became widespread the use of the hovercraft would be restricted The large

  • Opening Goolwa Lock - Lakes Need Water
    via Mayor Mchugh has at rallies pushed the fresh water barrow relentlessly Now that the Goolwa Pool is being raised to 0 7m with fresh water from Lake Alexandrina the mayor is lobbying for the lock to be opened by the long weekend in October 2009 through to Easter 2010 I believe the Goolwa channel s state worsened last year high salinity levels because the Lock stayed opened until the

  • Lower Lakes Crisis - Lakes Need Water
    will be lost to evaporation within a few weeks click on image to enlarge It is disappointing to hear your statement that you are committed to a fresh water solution for the Lower Lakes Minister Penny Wong has stated that there is not enough water in the whole Murray Darling system to save the Lower Lakes which would need about 1 000GL immediately and then an ongoing commitment of further water to maintain the level This also flies in the face of predictions that we are likely to experience continued dry conditions with low flows to South Australia The spectre of acidification of the total water body in Lake Alexandrina is a very real one and is predicted to occur when the level reaches 1 5m AHD If this occurs there will be very little that could survive in these waters As well the problem of exposed acidic soils will continue to threaten vegetation fauna agriculture viticulture and societies living in the path of the prevailing wind which will be laden with toxic dust The so called bioremediation efforts are unproven and so far have only be tried in a very small area around Goolwa with the rest of the Lakes being totally ignored To treat the whole system with this method would be an immense task which would take time which we do not have at the moment and is likely not to work in the long term This is truly a crisis of immense proportions similar to that which occurred with the Aral Sea I beg that you reconsider your Fresh Water Only solution and seriously plan to return the Lower Lakes to the estuarine condition which they have been in the past A tidal estuary would become a new vibrant wetland supporting biological diversity and thereby satisfy

  • Water pipeline for Point Sturt - Lakes Need Water
    water this summer by a government who states they consult but hasn t at least not since August 07 We will thus not have any water if at all until well into 2010 Senator Wong has clearly indicated that the SA Government provided a list of priority projects around the lower lakes Evidently Point Sturt was not included We are thus being effectively penalised for heeding the advice of three SA water officers who told community members at a meeting in August 07 not to bother applying for water Apparently also according to Senator Wong July 24th ABC radio 891 decisions on who to put forward to Canberra were made on the basis of representations made to Rann and Maywald The Government that repeatedly says they consult told us nothing about this Our Water Minister callously indifferent to our needs stated in a recent letter 17th July that we could do that connect to SA Water right now if we paid 100 000 per property She in coming from a rural electorate herself knows how insulting such a comment is She knows we haven t got that kind of change Our Water Minister also stated in estimates in early July As I have advised those communities in written correspondence probably September referring to the date when contingency outcome of creeks pipeline may be known The trouble in the time frame referred to no such correspondence was received by anyone in this community either from the Water Minister or from anyone purporting to represent her Our Water Minister who claims to consult won t even reply as at 16 8 09 to a request to attend a meeting to answer questions So even though it is clearly the fault of our State Government in failing to identify our need to replace

  • Freshwater vs seawater: be careful what you wish for - Lakes Need Water
    the environmental crisis in the Lower Lakes Insisting on freshwater only means that in this time of drought there is only freshwater coming from the local tributiaries and the water left in Lake Alexandrina That s only enough freshwater to cover the acid sullphate soils now exposed between Goolwa and Clayton The protestors have given the Government no choice but to build the regulator dam at Clayton to contain the

  • Meningie, fishing paradise - Lakes Need Water
    licensed fishers many from Milang working the grounds from Point Sturt to Point McLeay No they were not fishing freshwater fish but in fact the estuarine Mulloway As a bonus they were also fishing the delta of Currency Creek and the Finniss River but again not for freshwater species but yelloweye mullet Sure there were times this changed due to river flow when the occasional cod made its way south

  • Lower Lakes and the Drought - Lakes Need Water
    want just doesn t make sense No one blamed the government for the 1956 floods or for Cyclone Tracey that would have been ridiculous To blame the government for this extremely severe drought is equally ridiculous The Murray Darling system is extremely variable with inflow in more than half of all years being either well above average or well below Occasionally there are extremely high inflow years big floods or extremely low inflow years droughts This drought is a record in both severity and length and it is continuing Governments are clearly responding to the situation not creating it Why would anyone want to take this action if it wasn t necessary Desperate action to save what can be saved in these desperate times The environmental crisis is a very obvious fact emptying lakes wetlands becoming dry lands but what has the government actually done to cause this and to generate such vehement criticism They can t blame the Wellington Weir it hasn t been built yet They can t blame the regulator it has not yet been completed They can t even blame the irrigators upstream because there has not been enough water for them either only one third of the entitlement cap which we all agree is too much and needs fixing for the future was taken out last year a huge reduction They claim that the government is exaggerating the acid threat but the evidence is clear and acid corrosion of structures from windblown lakebed dust is also a fact The water shortfall created by the drought has become the overwhelming causal factor for the crisis we see before us diversion upstream has become minor in comparison the numbers tell the story but the protest groups are in drought denial they want to blame the government An

  • Plight of Lake Albert - Lakes Need Water
    to Lake Albert and instead allow it to dry out despite an economic alternative being available for the lake to be fed salt water from an adjacent Ramsar site being the Coorong This is in breach of the Ramsar convention charter which intends to preserve nominated wetlands by whatever means possible which should include at the very least a priority link to the Coorong another Ramsar wetland with Lake Albert even as an interim measure to ensure the continuation of the Lake Albert Wetland See paragraph 2 of article 4 of the Convention below Where a Contracting Party in its urgent national interest deletes or restricts the boundaries of a wetland included in the List it should as far as possible compensate for any loss of wetland resources and in particular it should create additional nature reserves for waterfowl and for the protection either in the same area or elsewhere of an adequate portion of the original habitat If this offends the intention of the Ramsar convention many will say it is the drought conditions that have led to this decision However this decision to cut off Lake Albert ignores ecological studies that show the lake history was one of
