Water column profiles were conducted at eight locations in the Providence and Seekonk River estuaries on May 7, 2025 using a Seabird Electronics profiler. In the five days leading up to the survey, 2.1 inches of precipitation were recorded at T.F. Green. Water column stratification varied between the sites this week from weakly stratified at Point Street Bridge to strongly stratified at all other sites.
Dissolved oxygen (DO) conditions were not observed to be below the hypoxia threshold (2.9 mg/L) at any site profiled this week. The highest fluorescence recorded this week was measured around 1.5 meters below the surface at Edgewood Yacht Club.
