Rainfall that flows from the catchment into the creeks and rivers is stored in the region’s dams.
Water storage is a major and critical part of Seqwater’s business, and we aim to maintain and enhance the quality and biodiversity of lakes and land to maximise sustainability.
Seqwater owns and operates 26 dams, 47 weirs and 14 bores and aquifers supplying as much as 90 per cent of South East Queensland’s drinking water supply. View a map of Seqwater's dams and other assets.
