Freshwater recreational water quality report

Summer water quality monitoring

During the summer months we monitor the quality of fresh water for recreation by measuring E. coli at river and lake sites.

Weekly samples are taken from December to February. For the Waikato River, at Hamilton, weekly samples are taken from November to March.

Data for this summer is presented on this page, below. For more information on the sites we monitor and how the water quality is tracking over the years, visit the LAWA site at Can I swim here?"
