Mr Gentleman: The answer to the member’s question is as follows:

(1) The Isabella Pond has been drained three times since October 2016.


a. Isabella Pond was first drained in mid-April 2017 to allow the expansion of Isabella Weir to be undertaken and the wetlands to be constructed. The pond was temporarily refilled in mid-November 2018 following completion of the weir and wetland construction to allow a ‘first fill’ inspection. In mid-February 2019 the pond was drained for a second time. Sealing of minor shrinkage cracks in the weir wall occurred during this time which were identified during the ‘first fill’ inspection (and which were an anticipated part of the construction process). In late March 2019 the pond levels were lowered for a third time. During this time additional inspection and reporting on the shrinkage crack sealing was undertaken. The pond was refilled in early May 2019.

b. There is no cost associated with each draining and refilling as this is part of the Contractor’s scope of work for the Isabella Weir expansion project.

(3) The pond will be lowered again in June 2019, to allow further shrinkage crack repairs to be undertaken. Following this (in approximately July 2019) the pond will be refilled, and the weir wall again inspected. Should all shrinkage cracks be successfully sealed then no further emptying of the pond will be required.

(4) The project has been completed within budget.
