“Is the lagoon getting better or worse?” is the question that the IRL Health Update will answer.

Our lagoon community is working very hard to bring our lagoon back to a healthy, productive estuary to be enjoyed for generations to come. We know its going to take a long time to see results. This MRC IRL Health Update assembles the most accurate data of lagoon conditions to complete a comprehensive health analysis to see how conditions are changing over time.

After going through an extensive process to define health indicators, MRC and partners at Applied Ecology Inc. collected and analyzed data to scores ten regions of the lagoon based on each region’s unique healthy target. Health Indicator scores and a total water quality index score are provided for each region.

The ten regions of the lagoon as listed on the map are

Mosquito Lagoon (ML)
1 ML North
