Between the middle of 1995 and the middle of 1996, approximately 300 000 m3 of sediment was dredged from the Patawalonga Basin. The sediment was deposited in ponds along Tapleys Hill Road and the water drained from it. In July 1996 accelerated drainage measures were instituted which allowed the material to be removed from the ponds early and used in the construction of a golf course immediately south of the ponds. The area had previously been used for waste disposal and some of the sediment was used to form an additional cap over the landfill.
