Dam Improvement Program

Seqwater has commenced its Dam Improvement Program to ensure the region’s dams continue to meet national standards. The program will see us upgrade some dams and reduce the water levels of others until such time as upgrade works can be completed. Leslie Harrison Dam is one of the dams to be lowered and later upgraded.

We commenced lowering the water level of Leslie Harrison Dam on Tuesday 10 June 2014, with carefully controlled water releases through the dam gates. The slow releases will continue until the water level reaches approximately half of the dam’s capacity. This will allow further assessment to be undertaken to inform the final upgrade works required and the timing of these upgrade works.

Visit our Dam Improvement Program page for more information and to subscribe to our e-updates.
