This data release contains data for the hydrologic and water-quality characterization of Levittown Lake, from April 2010 to June 2021. Three child items were included in the data release to summarize the results of the (1) community productivity through the light and dark bottle method (2) two diel data collection efforts, and (3) spatial data associated with the bathymetric survey conducted at Levittown Lake to contour the lake bottom. Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides...

This dataset contains tabulated-data of dissolved oxygen concentrations collected at Levittown Lake, Toa Baja, Puerto Rico. The standard light-dark method was used to determine the primary productivity in phytoplankton. The method consists in the in-situ incubation of two light-and-dark bottles for approximately four hours. Dissolved oxygen concentrations were estimated using the Winkler method. A total of twelve in-situ incubations were conducted on a monthly basis from April 2010 to June 2011. For each bottle incubated, two or three titrations were conducted and an average of the dissolved concentrations is calculated.

This dataset contains the selected physical properties and chemical constituents that were measured at Levittown Lake, Toa Baja, Puerto Rico during a diurnal cycle. Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides for the northern coast of Puerto Rico. The community primary productivity is defined as the rate at which organic matter is created by photosynthesis and is important for supporting the food web in aquatic ecosystems. The field data collection included the measurement of physicochemical...
