ST LUCIE FINAL REPORT

Perhaps the greatest tragedy that is constantly in playing out in our declining St Lucie River/Indian River Lagoon is the tremendous sediment infill covering its once white sands, seagrasses, and benthic communities.  This began heavily in the 1920s with the connection of the St Lucie Canal (C-44) connecting Lake Okeechobee to the South Fork of the St Lucie River, and then increased in the 1950s and beyond with the construction of canals C-23, C-24 and C-25.

It must also be noted that the St Lucie River/SIRL underwent great changes when the St Lucie Inlet was opened permanently by local pioneers at the encouragement of Capt Henry Sewall in 1892. (Historian, Sandra Henderson Thurlow) Prior to that time, the Southern Indian River Lagoon and St Lucie River had been “fresh” —-fresh and brackish waters and their communities of plants and animals “came and went” with nature’s opening and closing of the “Gilbert’s Bar Inlet” over thousands of years….

Since 1892 the St Lucie River has been a permanent brackish water “estuary…” and until the opening of the St Lucie Canal was teeming with fish and wildlife and considered the “most bio-diverse estuary in North America.” (Gilmore 1974)

Anyway, today we have a very special guest, and one of my favorite people in the world, Dr Gary Goforth, to share with us information on 2015 sediment statistics entering the St Lucie River from C-44, our most damaging canal. (DEP 2001:(http://www.dep.state.fl.us/southeast/ecosum/ecosums/C-44%20Canal%20.pdf)

Dr Goforth recently sent out an email,  and I ask him if I could share the information; he agreed. He states:

“The pollutant that has been consistently left out of discussions is the sediment load to the estuaries from Lake Okeechobee – over 2 million pounds to the St. Lucie River and Estuary in 2015 alone; almost 4 million pounds to the Caloosahatchee Estuary.” (Dr Gary Goforth)

Isn’t that awful? “We” are filling the river in….smothering it.

The slides Dr Goforth included are the following:

Flows and loads for the period January 1, 2015-May 31, 2015. (Dr Gary Goforth 2015)

Please click on image above to read the numbers. Mind boggling!

This second and complicated image below shows “flows” into the estuaries from Lake O into the St Lucie, Caloosahatchee, and the Everglades Agricultural Area. Generally speaking, the Army Corp of Engineers in discussions with the South Florida Water Management District,  began releasing into the St Lucie River January 16, 2015 until late May/early June. About 3 weeks ago.

Flows between January 1 and May 31, 2015. All flows in acre feet and subject to revision. (Dr Gary Goforth,, 2015)

Recently our river waters have looked very beautiful and blue near Sewall’s Point and the Southern Indian River Lagoon and water quality reports have been more favorable.  Nonetheless the river, especially in the South Fork and wide St Lucie River, is absolutely impaired as there is not much flushing of these areas and the sediment infill is tremendous. The seagrasses around Sewall’s Point and Sailfish remain sparse and algae covered when viewed by airplane. Blue waters does not mean the estuary is not suffering!

Months ago I wrote a blog, that is linked below, focusing on south Sewall’s Point’s river bottom infill history,  and depths that  have gone from 19, 15, and 14 feet in 1906, to 4, 8, and 7 in 2014—and looking on the Stuart side, north of Hell’s Gate, the 1906 map shows 10, 8 and 12 feet and a 2014 NOAA map reads 2; 3; and 4 feet!

Insane….so many changes!

Our government has filled and dredged our precious river…elements of this inputting sediment become MUCK…..

I’ll end with this:

The River Kidz say it best, although my mother didn’t approve of the tone: 🙂

Thank you Dr Gary Goforth for sharing you expertise on the science of the St Lucie River/Indian River Lagoon, Lake Okeechobee and Everglades. Please check out Dr Goforth’s website here:((http://garygoforth.net))

headshot-jtl-2013About Jacqui Thurlow-Lippisch:

Although born at Travis Air Base, California, Jacqui considers herself a native of Stuart, Florida, having moved there at eight months old. Her father’s family, originally from Syracuse, New York, has lived in Stuart since 1952. Her mother is a 5th generation Floridian from Gainesville. Jacqui is a Daughter of the American Revolution.

Jacqui is journalism graduate of the University of Florida, and an education master’s graduate of the University of West Florida. She went on to teach English and German and later after a serious accident of breaking her neck, started selling real estate. Later, she ran for public office having served on the Town of Sewall’s Point Commission since 2008, and is former mayor. During this time she saw the opportunity to help showcase the work of a locally formed river group, the River Kidz, and this has been her passion ever. She incorporates youth/river education  into her political work for the St Lucie River/Indian River Lagoon.

Jacqui is the treasurer/secretary of the Treasure Coast Regional Planning Council; has chaired the Florida League of Cities Environmental and Energy Committee; was chair, and a six year member of the Treasure Coast Council of Local Governments; is an alternate for the Water Resources Advisory Commission for the South Florida Water Management District; and is a board member for Harbor Branch Oceanographic Institute Foundation, in St Lucie County.  She also serves as a board member (ex-officio) for the Rivers Coalition Defense Fund, and is head administrator for her beloved River Kidz, now a division of the Rivers Coalition.

Jacqui’s reach involves not only local, but state and federal government. In 2013,  she served on Senator Joe Negron’s panel for the Select Senate Hearing on the Indian River Lagoon and Lake Okeechobee. In 2014, she actively supported the elections of both Senator Joe Negron and Congressman Patrick Murphy who have both been strong supporters of  Indian River Lagoon issues. In 2015, she is part of the Florida League Cities Treasure Coast Advocacy team to influence and educate Tallahassee. Jacqui received the Everglades Coalition’s 2015 “John V. Kabler Award” for “Grassroots Activism” working to organize and educate the public, generating grassroots support for Everglades restoration.
