Dynamics of internal nutrient loading in a eutrophic, polymictic lake (Lake Rotorua, New Zealand)
Lake Rotorua is a large (80 krn2), polymictic, eutrophic, shalJow (mean depth 10.8 m) lake in central North Island, New Zealand. Blooms of cyanobacteria and occasional anoxia of bottom waters are characteristic of the water quality in the lake during summer months (Dec-Mar.). This study examines …
