As part of the Dam Improvement Project at Lake Kurwongbah, we would like to advise you of some geotechnical investigations that will be conducted next week on the Sideling Creek saddle dam, main dam and spillway area.

Seqwater contractors will be undertaking works for about four weeks, subject to any wet weather or unforeseen project delays. Work will be conducted from 7.00am to 5.00pm Monday to Friday.

Geotechnical works include:

  • Digging of test pits with an excavator on the saddle dam toe, main dam crest, downstream berm and spillway training walls
  • Drilling boreholes on the saddle dam crest, main dam toe and downstream berm 
  • Concrete cutting on the spillway chute channel

Access to the lake and recreation areas will not be affected during geotechnical works for permitted recreational activities.

If you would like more information about this project please contact the Seqwater Community Relations team on 1800 771 497 or email

 We thank you for your patience and understanding while we undertake this essential work.
