Water Quality


Established in 1998, the Florida Oceanographic Water Ecosystem Surveys (FLOWSS) program assesses the trends and changes in water quality throughout the St. Lucie Estuary (SLE) and southern Indian River Lagoon (IRL).

Our volunteer citizen scientists record water temperature, salinity, dissolved oxygen, pH, and water clarity on a weekly basis. These parameters provide valuable insight to the current health of the estuary and the suitability of this habitat for key indicator species. Our program has 47 active water quality monitoring sites across 10 zones in the SLE and IRL.

Weekly Water Quality Reports

Weekly volunteer data is assigned a habitat health grade and compiled alongside data collected by South Florida Water Management District (SFWMD) and Florida Department of Environmental Protection (FDEP). We publish this data in a weekly report to give a snapshot of current conditions in the IRL and SLE.

Annual Reports

Water quality data collected by our volunteers is key to creating our weekly reports but also contributes to a larger data set. By compiling this data into an Annual Report we are able to provide valuable insights into annual trends and seasonal changes in ecosystem health.
