Taylors Regulator Fishway

Project Overview

Ertech was engaged by Goulburn-Murray Water (GMW) on behalf of the North Central Catchment Management Authority (NCCMA) to construct a new fishway as part of a broader Native Fish Recovery Plan to remove barriers to fish passage and connect 400km of stream and wetlands to 530km of the River Murray.

Taylor’s Regulator is located 8km west of Gunbower in the Mallee Region of northern Victoria. The regulator is located on Taylors Creek, which is used to convey water to irrigators via Kow (Ghow) Swamp and the No. 1 Channel. Taylors Creek regulator is located approximately 2km upstream of Kow (Ghow) Swamp in one of Australia’s most significant areas of cultural heritage.

Critical to the success of the project is maintaining flows past the construction site during the winter period for river health and channel filling operations, and ensuring the works are completed ahead of the 2023/24 irrigation season. Ertech’s temporary works strategy put forward at tender facilitated swift installation and removal of the works, allowing for an extended timeframe to complete the project.
