Lake Georgina is a highland lake in the upper Rakaia River catchment, covering an area of 17.5 hectares, with a maximum depth of 11.7 m. In recent times, the lake has shifted towards a eutrophic state (in regard to water quality), fuelled by an increase in nutrient enrichment and algal productivity. The lake is popular among kayakers and fishermen (source lawa.co.nz).
