Scope of works performed at South Para Reservoir were as follows:

• Mobilise to site and set up temporary facilities.
• Upgrade access track, storage, and turn-around area, ensuring delivery trucks can reach work zone.
• Carefully delineate work zone via flagging, in consultation with SA Water representatives.
• Install sediment and erosion control devices downstream of works.
• Clear and grub all vegetation strictly within the agreed delineated work zone.
• Excavate and prepare base at location of new concrete culverts and headwalls including:
  –  Upstream reinforced concrete cut-off wall.
  –  Upstream and downstream rock lined weirs.
  –  Concrete bed, 100mm thick nominally, to culvert invert with randomly placed D350 rock, creating the fishway structure.
  –  Rock armouring of headwalls.
• Construct rock lined swale from existing DN900 MSCL pipe under fire track to river.
• Build-up and rock armour sub-base of hiking track either of culverts to underside of hiking track, enabling connection of the two banks of the river by the track.
• Construct hiking track using cement treated quarry rubble.
• Manage minor river flows through the works.
• Remove all flagging, sediment, and erosion control measures from river.
