600 acres of Seagrass is Dead in “One of the most Biodiverse Estuaries in North America,” SLR/IRL

I was on the Army Corp of Engineers Periodic Scientist Call this past Tuesday. These are excellent calls and one learns quickly the difficulties and the burdens of water management for our state and federal agencies in the state of Florida. I have participated in the calls as an elected official for the Town of Sewall’s Point since 2012.

This past Tuesday, something was said that struck me. Mark Perry, of Florida Oceanographic, reported something to the effect that over 600 acres of seagrasses inside the St Lucie Inlet are now “sand bottom.”  Six hundred acres….

I went home and asked my husband that night at dinner…”Ed could it really be six-hundred acres? The seagrasses dead?”

“Easy.” He replied. “Just think of when I lived at the house at 22 South Sewall’s Point road when we first got married in 2005, and we’d walk out with the kayaks and there was lush seagrass  all the way out ….well that’s gone–its gone all around the peninsula–you can see this from the air.”

Ed took some aerial photos the day after this conversation. Yesterday. I am including them today.

—-So it’s true, 600 acres of seagrasses are dead in one of the most bio-diverse estuaries in North America, the St Lucie River/Indian River Lagoon or southern IRL —for many years, as many of us know, confidently cited as not “one of,” but rather, “the most diverse…”

The Army Corp has been releasing from Lake Okeechobee this year since January 29th, 2016. We are only in June and there is more to come. Yes there is…there is “more to come” from us. There has to be. Because we are losing or have lost —everything.

Please compare the 1977 photo and then the 2012 map to photos taken yesterday. Please  don’t give up the fight to bring back life to this estuary.

St Lucie Inlet area, the Crossroads and Sailfish Flats between and around Sailfish Point and Sewall’s Point in the confluence of the St Lucie River and Indian River Lagoon near the St Lucie Inlet. This area has been inundated by release from Lake Okeechobee and area canals for many years most recently particularly Lake O during 2013 and 2016.
