Annean Station Management Plan, A A. Mitchell

Resource management technical reports

Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.

Chemical Sealing Of Small Earth Dams Using Sodium Tripolyphosphate, R G. Pepper

Technical Bulletins

As the seepage rate of 3.1 mm/d was considered too high, sodium tripolyphosphate (STPP) was dissolved in the dam water in an attempt to disperse the clay and reduce the hydraulic conductivity. Application of STPP altered the original sealing layer at first and, as seepage progressed, a new seal started to form at a depth of 0.8 m below the batter. The seepage rate was reduced to 0.39 mm/d and the hydraulic conductivity of this new seal was 2.0 x 10-9 m/s.
