Water column profiles were conducted using a Seabird Electronics profiler at five locations in the Providence River and one location in the Seekonk River on October 15, 2025. In the five days leading up to this there were 2.30 inches of rain recorded at T.F. Green International Airport (Warwick, RI). The water column was strongly stratified at India Point Park and Phillipsdale Landing, and weakly stratified at Bullock’s Reach, Edgewood Yacht Club, Pawtuxet Cove and Pomham Rocks.
Dissolved oxygen conditions were not below the hypoxia threshold (2.9 mg/L) at any of the visited locations. The highest fluorescence reading was observed about 1.25 meters below the surface at Phillipsdale Landing.
