Indian River Lagoon Report Card Shows Water Quality Improving; However, Seagrass Is Not Recovering As It Has Historically

Water is clearer, and harmful algae is on the decline in the Indian River Lagoon, which stretches along more than one-third of the east-central coast of Florida, according to the annual Indian River Lagoon Report Card, published by Marine Resources Council (MRC).

Read the Report Card
Infrastructure improvements and behavior changes that are reducing storm water runoff, untreated sewage discharges, faulty septic systems, and residential sources, such as pet waste, and fertilizer are helping.

“We’re making important progress,” said MRC Executive Director Leesa Souto, PhD. “While we continue that progress, we need to consider a new and concerning phenomenon.”

The report card also shows that seagrass, the essence of life in the lagoon, is continuing to die. Historically, seagrass has recovered as water quality improves. Florida currently bases water quality in the lagoon on the levels of nitrogen, phosphorus, and chlorophyll-a, as well as turbidity, water clarity.

“Many other pollutants, herbicides and pesticides need to be added to lagoon water quality testing to determine what’s causing the seagrass to die,” said Dr. Souto. “Our theory is that new or increased loads of contaminants may be causing this new seagrass phenomenon; however, more extensive testing is needed to determine the cause.”

100 Friends of the IRL

MRC Is Now Seeking “Friends of the Indian River Lagoon”

Friends of the IRL is a group of businesses, organizations, clubs, individuals, HOAs, and stakeholders dedicated to funding the IRL Report Card. The proposed support is $1,000+ per stakeholder, intending to raise over $100,000 each year to add more tributaries to the data set, include fisheries data, and expand outreach.
