IRL Report Card

The report card is a visual representation of the lagoon’s condition through the data collected as part of the state’s monitoring program to determine if state regulatory standards are being met. Bottom line is, we need to do more.

The 2020 Report Card includes:

  • 137,202 agency data including 25 years of seagrass and 23 years of water quality data
  • 10 lagoon regions and 12 tributaries covering from Ponce Inlet to Jupiter Inlet
  • Scored and color-coded tables and maps to easily see changes over time and space

The Indian River Lagoon Health Report Card represents the successful outcome of a public-private partnership between MRC and Applied Ecology Inc. (AEI) who have worked closely since 2015 to create an understandable translation of water quality and seagrass data. The report has successfully been used to guide scientific investigation, raise awareness, inspire advocacy, and inform policy-makers.

Reading the Report Card Scores (0 Is Bad and 100 Is Excellent)

Read the report card scores like you are reading school test scores (0 is bad and 100 is excellent). We have done the hard work of creating a simple score based on an off-set calculated as the difference between the regulatory target and the actual condition. These off-sets were standardized into a score from 0–100 with some additional room on either side for scores to go higher or lower than the current period of record. A score of 80 meets the regulatory target and is considered above average and is colored green. To learn more about how scores were calculated, to see the targets for each region, and to read other sciencey stuff, check out the 2020 Health Assessment Methodology Report.

The report card data were collected by state agency personnel and sent to a certified laboratory for analysis. All data were quality assured before being released to the public, a process that takes 6–12 months. If the actual condition is better than the regulatory target, it is colored in green (score of 80 or above).

Tables show the lagoon region scores over time with 23 years of water quality data and 25 years of habitat quality (seagrass) data. Maps show differences in regions of the lagoon and sample locations in a single year.
