LagoonWatch: Citizen Science in Action

LagoonWatch is MRC’s signature citizen scientist water quality monitoring program for the Indian River Lagoon. For more than 30 years we have trained and equipped hundreds of volunteer monitors to collect weekly data on a dozen water quality parameters (including pH, salinity, and dissolved oxygen levels) of the lagoon’s waters. Monitoring locations cover the entire expanse of the lagoon from New Smyrna Beach in the north to Jupiter Inlet in the south.

We held a LagoonWatch Open House on January 14, 2023 to introduce the greater public to the LagoonWatch Program and to recruit new volunteer monitors.

We continue to look for new monitors and new locations at which to monitor. Please contact us if you would like to help us better understand the complexities of the Indian River Lagoon.

Collaborating with Surfrider’s Blue Water Task Force

MRC is working with the Space Coast chapter of Surfrider’s Blue Water Task Force to test local waters for enterobacteria, an indicator used by the State of Florida to assess the health of recreational waters.

Samples are collected twice monthly and the results are currently being reported on the Blue Water Task Force’s website. Follow this link to see the locations being monitored and the results:
