Cirata is one of three reservoirs lay in Citarum River, where the water body is used to fish culture in floating net. Lately, one or two times in a year, fish in the floating net die massly because of the water quality of reservoirs have worsen, which resulted from the entering of organic pollutant from human being activities in and outside of the Reservoir. This paper is written to reveal contribution of organic waste from fish culture in floating net represented human being activities inside of the Reservoir on the worsening of water quality Cirata. The result revealed that the Reservoir Cirata continually has been polluted by organic waste, which gradually resulted in the worsening of water quality indicated by increasing chemical oxygen demand (COD) and concentration of chlorophyll-a (Chl-a), and decreasing secchi disk. This study indicated that on 1997, fish culture using floating net (internal loading) in Reservoir Cirata contribute the nutrient three times than domestic and agriculture (external loading). This situation is guessed still going on hitherto, therefore the reservoir become very hypertrophic, as giant cesspools, and resulted in death of fish massly
