Documenting the Discharges, December 2020

Documenting the Discharges, December 2020

Eyeonlakeo

I posted most of these photos on Facebook, but today I will give explanations and document on my blog. From above, our St Lucie/Indian River Lagoon remains beautiful, but we must be sensitive to the losses beneath the waters. These aerials were taken during  a “slack tide” between 12 and 2pm on December 9, 2020 by my husband, Ed Lippisch. December 9th was the last of five days the ACOE stopped discharging from Lake Okeechobee; however S-80 was discharging “local runoff.” (Click on chart above.) Unfortunately, due to high lake level and lack of storage reservoirs, since these aerials were taken, the ACOE has begun ramping up Lake discharges once again. 

Below Lawrence Glenn of the South Florid Water Management gives a comprehensive ecological report covering low-salinities and loss of oyster spat in the St Lucie and other aspects, positive and negative, for the entire Everglades system.

Below is an explanation of aerials documenting discharges December 9, 2020. All photos by Ed Lippisch.

S-308 at Port Mayaca, Lake Okeechobee closed on December 9, 2020. No algae visible.

-Looking north to Sailfish Flats between Sewall’s Point and Hutchinson Island. This area has greatly degraded since 2013 as far as loss of seagrasses and fishing opportunities 

-The area below, especially around Sailfish Point, was once considered “the most biodiverse estuary in North America” as documented, first, by Grant Gilmore

-This photo reveals seagrass loss across many areas of the Sailfish Flats 

-Another view between Sewall’s and Sailfish Point, a seeming desert…

-Sewall’s Point is a peninsula surrounded by the St Lucie River on west side, and Indian River Lagoon on east side 

Ed Lippisch, selfie. Thank you Ed! 

As you can tell, I have lots of people helping me. Whether it is Ed flying or my brother Todd who provides an incredible easy to read website called EyeonLakeO. You can click below to check it out. The more we know, the more we document, the more we can overturn the destruction of our beloved estuary…

Comparison Update of Lake O Discharge Events, 1998, 2013, and 2016, SLR/IRL

 

Summary of Lake Okeechobee 2016. Dr Gary Goforth.
Comparison of Lake Okeechobee releases to the St Lucie River & Estuary 2016, Dr Gary Goforth.

This year, the Army Corp of Engineers– with input from the South Florida Water Management District, and other stakeholders— has been discharging from Lake Okeechobee into the St Lucie River and southern Indian River Lagoon since January 29th, 2016. Today will review an April update.

We as citizens must pay attention and know what is happening to the river so that we can intelligently fight for its future.

Dr Goforth’s chart above gives a good visual comparison of 2016’s discharges, thus far, compared to those of 1997/98, another El Nino year with fish lesions, fish kills, and toxic algae reports. This chart  also compares 2013, our recent “Lost Summer,” when toxic algae blooms filled the river, on and off, for about three out of five dumping months. (–Running May through October, 2013.)

One can see, that Lake Okeechobee’s 2016 discharge amounts are quickly approaching the total numbers released in 2013— although well below those of 1997/98.

Although discharges have been lessened lately, with the Army Corp of Engineers reporting a possible La Nina indications for the 2016 Hurricane season, (4-26-16 ACOE Periodic Scientist Call) considerably more rain could be on the way.

With the lake sitting at 14.29 today,  —a high level going into “wet season,” starting June 1st—we should all be watching the situation very closely. Hopefully 2016’s total Lake O release numbers will be nowhere close to 1997/98.

We must continue to advocate hard for a third outlet, and land purchase south of the Lake Okeechobee, as this is the only way to spare our rivers’ repeated total destruction.

Thank you to Dr Goforth for his contribution today.
