One water column profile was conducted using a Seabird Electronics profiler at Conimicut Point (Providence River) on August 20, 2025. In the five days leading up to this there were 0.01 inches of rain recorded at T.F. Green International Airport (Warwick, RI). The water column here was well-mixed with no dissolved oxygen concentrations below the hypoxia threshold (2.9 mg/L). The highest fluorescence reading was measured at about 3.5 meters below the surface.
