Why is the Lagoon so discolored in Sebastian? We have answers

The Indian River Lagoon along the banks of Sebastian has a weird brown coloring. At first, we thought it might be brown algae.

Duane De Freese, Ph.D., Executive Director of IRL Council & Indian River Lagoon National Estuary Program, says it doesn’t look like brown algae.

“That looks like tannins from the massive amount of freshwater being discharged through stormwater and groundwater because of the rains,” Freese said.

Kathy Hill from the IRL Council also confirmed what Duane Freese stated.

“I agree with Duane; it looks like tannic river water. I drove over to St. Sebastian yesterday afternoon, and it was pretty darkly colored from the discharge coming off of it,” Hill said.

With more rain in the forecast and a possible tropical storm, we will probably see more of this in the coming days.
