Green’s My Favorite Color, but I Love When it’s Blue

Documenting the St Lucie River/Indian River Lagoon, 2021


Dr Scott Kuhns sent me aerials he took from the St Lucie Inlet this morning, July 28, 2021, at 10am from 2500 feet. Although due to rain there is local basin runoff and C-23/24 dumping into the St Lucie River, there is not Lake Okeechobee discharge mostly due to the presence of algae. So we have been fortunate and our waters have been looking great. So blue!  Beechcraft Baron

The second batch of photos I already shared on Facebook. My husband Ed took these photos Saturday, July 24, 2021, from about 1500 feet. Seagrass is budding back! One sees the darker colored runoff water inside the St Lucie River/Indian River Lagoon, but again, there is no Lake Okeechobee water thus still blue out over the nearshore reefs and closer to the St Lucie Inlet/Atlantic Ocean. Last, I will share Ed’s aerials inland of Lake Okeechobee taken on July 24, 2021 as well. The lake aerials show algae along the shoreline, but not so much further out. We must heal all our waters including this lake!

Hopefully there will not be a hurricane this season, and the waters of the St Lucie can continue to recover from previous long-lasting Lake Okeechobee discharges. In any case, Scott, Ed, and I will continue to document.

Thank you pilots!

In closing, I must admit that for my whole life, my favorite color has been green, but I love when it’s blue!

Reviewing Discharges to the St Lucie -so far-2021

July 9, 2021

If you are like me, it feels like 2021 is flying by. With the Fourth of July weekend having just passed, now is a good time to review this year’s southern Martin County discharges into the St Lucie River/Indian River Lagoon. In order to do this, I am presenting a wonderful chart created by my brother, Todd Thurlow. It is one of the many, displayed “in easy to read fashion,” on his web-site under “live-data” EyeOnLakeO. 

The image is best viewed large, but I’ll review first. Let’s look at how the chart is set up. Months are along the bottom and water amounts along the sides. We can easily see the green lines above 0. These lines show the times so far this year when the ACOE has been discharging from Lake Okeechobee. Blue lines show the surrounding basin runoff of the C-44 Canal. The red line displays S-308 Daily and the cream color shows S-308 Cumulative. S-308 is the structure at Lake Okeechobee; it can allow water to flow in two directions: from the lake into the canal, or from the canal into the lake. When the red line goes below 0 this means the water from the C-44 canal is going back into the lake. This is usually done for water supply reasons, is part of the historic lake operating schedule, and no matter when it’s done, is beneficial to the St Lucie.

My brother pointed out on Saturday, July 3, 2021, that the back flow was -3,344 cubic feet per second. This may have been occurring because the canals were being lowered for Tropical Storm Elsa. Todd notes “how different the weekend would have been with 3,344 cubic feet per second coming into the St Lucie River. All the weekend sandbar people would be flushed out with green brown water.” 

I agreed!

Take a look at Todd’s chart, and hopefully you had a wonderful Fourth of July weekend.
