Data for the Hydrologic and Water-Quality Characterization of Levittown Lake, Toa Baja, Puerto Rico, April 2010 – June 2011

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 for the northern coast of Puerto Rico. The standard light-dark method was used to determine the primary productivity in phytoplankton. The method consists of 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. The bathymetric survey of the Levittown lake was conducted on January 11, 2011 to contour lake bottom and calculate the water volume of the lake at mean sea level. The survey was conducted using a bathymetric/land survey system (BLASS) interfaced to a depth sounder.
