Water column profile data was collected at seven sites on September 20, 2023. However, due to an equipment deployment issue, only the data from the Phillipsdale Landing site was usable. In the five days leading up to the survey, 1.55 inches of precipitation were recorded at T.F. Green.
At the Phillipsdale Landing, the water column here was strongly stratified. Dissolved oxygen (DO) conditions were not observed below the hypoxia threshold (2.9 mg/L), but approached this threshold near the very bottom of the water column. Fluorescence readings at this site were relatively low, but reached a maximum value approximately 2 meters below the surface.
