The purpose of the diel study is to collect physicochemical parameters that allows for determination of the community primary productivity in Levittown Lake, Toa Baja, Puerto Rico. The main objectives of the investigation is to establish baseline data of the physical, chemical, biological, and bacteriological conditions of the Levittown Lake to define its seasonal variability over a 15-month period. The study included the lake’s main water body, the lake’s inlet/outlet channel Rio El Cocal), and the Caño El Hato drainage canal. The community primary productivity involves the entire ecosystem and may include phytoplankton, periphyton, and macrophyte organisms. The rate of organic matter generation by phytoplankton organisms is calculated through the light (translucent) and dark (non-translucent) bottles method, which can be used to determine net changes in the concentration of dissolved oxygen for a given volume of water within a given time interval (Clesceri and others, 1998). Through the dissolved oxygen diel curve analysis the net primary productivity ascribed to periphyton and macrophytes are determined by calculating the community net primary productivity minus the phytoplankton net primary productivity.
