use. The pond was divided into four sections and a power analysis was done to determine the number of transects required for sampling within each section. A petite ponar dredge will be used to measure the distribution of Hydrilla in the pond. A LI-COR datalogger with underwater quantum sensors will be used to measure the photosynthetically active radiation (PAR) irradiance data. A YSI meter will be used to measure the temperature at the sediment interface and through the water column. The LI-COR and YSI will be paired with the findings from the petite ponar to validate literature values. Average production will be calculated from the ponds inception and will be compared to reported production values for Hydrilla. If the values differ significantly, productivity cages will be deployed to monitor in situ production. Sampling will occur on a quarterly basis and will be ongoing for one year, to cover a full growing/dormant season for Hydrilla.
