Theresa Park Weir access track repair work

Following damage from multiple flooding events, WaterNSW is repairing a one-kilometre access track at Theresa Park Weir to provide safe and reliable access for WaterNSW staff.

Theresa Park Weir and fishway is located off McKee Road, Theresa Park in the Wollondilly local government area. The weir and fishway are currently inaccessible for essential maintenance and monitoring work.

What work is planned?

Repair work will include establishing a site compound and laydown area, temporary filling and compacting the road for equipment access, geotechnical investigations including drilling holes to collect soil and rock samples, stabilizing the slopes above and below the access track, installing drainage, resurfacing the track, repairing and replacing damaged assets along the road, and maintenance of the fishway.

• The construction work at Theresa Park Weir will be scheduled following the completion of the Environmental Assessment process, engagement with neighbouring landowners and stakeholders and consent from National Parks and Wildlife Service.

• Geotechnical investigation work will start in late 2024 and will take approximately four weeks. The main construction repair work is planned to start in early 2025 and will take ten months, weather permitting.
