-One can see river’s proximity to Witham Field in Stuart. These photos show darkness of St Lucie due to stormwater runoff off lands and canals C-23. C-24, and C-44. No Lake O discharges.

-St Lucie Inlet 

-Stuart Sandbar with many boaters. Water is dark with stormwater and canal runoff but remains to recreational standards.

-West now over S-308, Port Mayaca, Lake O – no visible algae from altitude of 1500 feet. Satellite images do show algae on west and middle of lake. SEE my brother Todd’s website  EYEONELAKEO for all info. -Although water looks good at St Luice Inlet at an incoming tide, the estuary is suffering from too much input. Read Florida Oceanographic’s update for details.

Today, August 22, 2021 Lake Okeechobee is at 14.39 feet. This recent TCPalm article by Ed Killer gives insights based on a recent media conference with Col. Kelly of the ACOE.

And the Rains Come Down; St Luice with No #LakeO

Ed, Scott, and I, part of your River Warrior team since 2013, continue to visually document the St Lucie River/Indian River Lagoon by air.  Although due to algae at the gates of Port Mayaca the ACOE’s lake schedule has not  subjected the St Lucie River to Lake Okeechobee discharges since April 10, 2021, the rains and stormwater runoff from surrounding lands and canals C-23, C-24 are flowing. I know I am not an official keeper of rain, however, the rain gauge in my garden has displayed significant rain over Sewall’s Point in the past weeks. See ACOE & SFWMD recent official documents below.

August 4, 2021

Today I will share aerials from Dr Scott Kuhns. A view from the Super-Cub. These aerials reflect a visual change in the water color due to the rain. The water is darker and contains sediment, and all other that runs off roads and lawns, and agriculture fields out west. Sometimes over a million acre-feet of discharge a years can come from C-23 and C-24 alone! We do not need any Lake O discharges on top of this. C-44 runoff (see canal map at end of this blog post)  is probably on the way as when the canal level is lower than the lake it is usually made to flow in our direction. Right now the lake is at 13.87 feet. Two tropical systems are being watched. Hopefully, we will not have a hurricane! The river over all has been looking great! Seagrasses slowly returning. Better fishing reports.

It is important we stay on top of things. Continue to advocate! Learn all you need to know about #LakeO on my brother Todd’s website eyeonlakeo.

Ok, here are Scotts photos. Compare the difference to July 28, 2021.

Dr Scott Kuhns, SLR/IRL, yesterday, August 5, 2021 at 10:00 am. Note Atlantic remains blue in color and St Lucie Inlet as well but there is a plume.  The estuary and Crossroads of the St Lucie River/Indian River Lagoon-they are more impacted. The final photo of St Lucie Locks and Dam’s S-80 structure is inland and thank goodness remains closed!  Thank you Dr Scott Kunhs for being our eye in the sky and longtime River Warrior documenter!

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!

Keeping Alive the Power of the Public Voice #2

I’ve had so many calls and reactions to my recent post “Keeping Alive the Power of the Public Voice,” that I’m going to keep sharing my photo archives of the “Riverlution.” Yes, today’s modern Florida water advocacy all started here in Martin County.

This next set of archived photos is dated August 10, 2013, Lost Summer (only seven days after the Rally at the Locks,) and labeled “Beach Rally for the River.” Photos reveal a large crowd at Stuart Beach and aerials of a black coffee/green algae St Lucie River/Indian River Lagoon. Terrible!

For me, one of the all time most inspirational photos is in this collection. I am displaying it as the first one. It shows a  little boy raising his arms in glee towards the sky as Ed’s original River Warrior -the yellow Cub- plane passes overhead and the flag flies! Save Our River! We are working not just for ourselves but for the future. Please keep the power of the public voice alive for all our Everglades’ rivers during the optimization of LOSOM. The voice of the people must direct policy and we must continue to lead the way!

Things Have Changed, but Things are the Same…

The Fourth of July 2021 was fun!

Ed’s family came to visit. I was thankful the water was in good enough shape that Ed and I could take everyone out to enjoy the St Lucie River/Indian River Lagoon. The highlight for me was after a boat ride to Peck’s Lake, building a sandcastle with Capri (7) and Cole (5) at St Luice Inlet State Park.

With my hands in the earth at the side of the sea in a place of my childhood, it was as if nothing had changed. Except building the castle out of re-nourished beach sand maybe. But Capri and Cole did not notice.

Ours became a wonderful sandcastle, and together we cheered “We will not retreat” and kept building and adapting as the ocean moved ever-forward. I did not say a word, but thought perhaps I was preparing them for sea-level-rise. In the end, Cole took a shell to the wall and informed Capri and me that a “dinosaur had arrived to destroy the castle!” Capri was not happy; but I assured that it was “OK” as the nesting sea turtles preferred flat sand and would appreciate the tear down.

-Capri (7) Aunt Jacqui (57) and Cole (5)The next day, Ed took the family up for a flight.

It was Capri’s first time and although I was nervous due to temperature and turbulence, she was brave and her parents supportive. All was wonderful, but it did feel a little weird saying: “Capri, don’t be surprised when the giant Lake Okeechobee is bright green.” At seven years old, she gave me the largest of smiles and I smiled back. Then I turned to Ed saying “Babe, you may needed to talk about cyanobacteria (blue-green algae) when up in the plane.”

Ed nodded concentrating on the flight.

Never in a million years would I think to myself that this would be the conversation. In any case, Ben and Capri had a great flight! Kelli and Cole stayed behind with me.

-Ed’s relatives. The Linder family: L to R. Ben, (nephew); Capri; Ed; Cole, & Kelli)-Ben, Capri, and Ed up in the airHere are some aerials of their flight, 7-2-21, 12: 57 pm:

-St Lucie River/Indian River Lagoon at Sewall’s Point, heavy local rain runoff, but no Lake Okeechobee releases.-S-80 St Lucie Locks and Dam, closed.-S-308 at Port Mayaca, Lake Okeechobee open for agriculture water supply but not going through S-80 to St Lucie River.-S-308, note algae inside structure leading to C-44 Canal.-Ed over Lake Okeechobee note age streaks and location of GPS near Clewiston. -Over western and central area of Lake Okeechobee -note GPS. Once we got home, there was no slowing down. Somehow the kids found Ed’s telescope up in the loft. Laughing, but embarrassed, Ed and I realized we had not taken it out in seventeen years!

We were able to look at a nearby oak tree, but not at the stars when they came out at night. The telescope had seen better days.

Even though we didn’t see the stars,  it was adorable watching Ed with his niece and nephew. And I though to myself, “things have changed, but things really are the same and we must show the way to the next generation.”

-Ed works the telescope with Cole (5) and Capri (7) after the kids  discovered it. -Capri looks towards the future…



Aerials 6-27-21 -St Lucie to Lake O

Yesterday, Sunday, 6-27-21 -at 2:15 pm, my husband, Ed, took a flight over the St Lucie River/Indian River Lagoon. In spite of significant local basin runoff, due to local rains, the river looked good.

Flying west -Lake Okeechobee at Port Mayaca showed no visible signs of algae from 1000 feet, however also on 6-27-21, Mike Connor, Indian RiverKeeper reported cyanobacteria within and around Port Mayaca’s S-308 gate; and on June 24, 2021, the Martin County Hearth Dept issued a BLUE-GREEN ALGAE BLOOM ALERT FOR THE WATERS NEAR PORT MAYACA. As expected,  The Department of Environmental Protection reports Algae in Lake Okeechobee at this time.

Florida Oceanographic gave a “B” for water quality in the St Lucie River for June 17-23.

Check out the SFWMD Ops_Position_Statement_Jun_22_28_2021

The ACOE reports the lake is at 12.66 feet 6-28-21 and there have been no Lake O discharges since April 10, 2021. Thank God! We continue to advocate for the health of the St Lucie and its residents. #NoLakeO

Enjoy the Flight! Enjoy the Water in the SLR/IRL! Ed and I visited Boy Scout Island on Saturday and the water was beautiful. The way Martin County is supposed to be! 

~Thank you Ed for being our Eye in the Sky since 2013~

-Sandbar St Lucie River/Indian River Lagoon-Sailfish Point, Sailfish Flats and Sandbar. Seagrasses are few, but there. Hopefully they will grow back if there are no Lake O discharges this year.

I think his first. “Thanks Ed!” 🙂-Lake Okeechobee at Port Mayaca, raining near Pahokee and south rim of lake. No visible algae but hard to see in this light. In any case, S-308 the gates at Port Mayaca are open only for water supply to agriculture and S-80 at St Lucie Locks and Dam remains closed thanks to the ACOE. Thus no Lake O water to the St Lucie. Hopefully they will remain closed for all 2021 and beyond!

Everglades 2021-Second largest nesting event since pre-drainage period in the 1940s

Words of Dr Mark Cook, Wildlife Ecologist | Restoration Scientist | Wildlife & Scientific Photographer | Public Speaker | Science Communicator/SFWMD

“As the rainy season finally kicks in after a late start, and the wading bird nesting now draws to a close, it’s time to reflect on a very successful nesting season. Final nest numbers and fledging rates are yet to be calculated but in general we can say this was the second largest nesting event (over 80k nests!) since the pre-drainage period in the 1940s, and very likely the most successful year in terms of the number of young birds produced! The photo here shows just one of the large flocks of young wood storks (note the yellow beaks not the black beaks of the adults) that recently fledged and are now recruited into the population. The late start of the wet season was certainly helpful because it allowed the vast majority of late hatching birds to fledge before the rains started and lost their food supply. It also extended the period of excellent foraging habitat which increases the probability of survival for these young, naive birds. It’s likely that all wading bird species nesting in the Everglades experienced a significant boost to their populations this year.” –Dr Mark Cook, 6-24-21, Facebook

Today I share photos of a helicopter tour taken June 18, 2021 under the direction of South Water Management Districts‘ Dr Mark Cook. Twenty-seven year veteran, JK Wells served as pilot, and Mr Sean Scully, Bureau Chief, Applied Science -Kissimmee River was a guest -just like me.

JK flew us “everywhere. This post will focus on Water Conservation Areas 1, 2, and 3. (WCA) and Everglades National Park. This flight was taken so that Dr Cook could document one of his final bird counts for the year. Most juvenile birds had fledged their nests. This is fantastic news. So we did not see the “super colonies,” some with up to thirty thousand birds, that were present just a few weeks ago -but we did see fledgling birds and parents and the Everglades landscape itself.  Spectacular!  I want to share these photos today.

~And kudos to the birds of 2021! So happy you had a great year! Thank you Dr Cook for letting me tag along!

-Pilot JK Wells, Mr Sean Sculley, JTL, and Dr Mark CookAt 7:00 am the machine rose like a dragonfly and West Palm Beach came into view. Within a short time we were over Water Conservation Area 1, also known as “Aurthur R. Marshall Loxahatchee National Wildlife Refuge.” This area is famous for its tree islands. -West Palm Beach below1. Water Conservation Area 1

-Tree island with remaining wading bird colony-Amazing tree islands in WCA1. “Tree islands are important centers of biodiversity in the Florida Everglades; they have two to three times the plant and animal diversity of the surrounding wetlands. This high diversity is due primarily to their higher elevation relative to the adjacent wetlands. In the natural Everglades system, water levels fluctuated seasonally with rainfall, and tree islands were the only sites that escaped flooding during the wet season. These seasonally dry sites provided refugia and nesting sites for animals and allowed tree and shrub communities to flourish.“USGS -Another view of this remarkable habitat! -Large tree island amongst smaller ones. The difference has to do with soil type and topography. Aren’t they spectacular? Biodiversity reigns here. -Note dead Lygodium or Old World Climbing Fern below that has been treated, now dead hanging in tree islands.Below: “Loxahatchee Impoundment Landscape Assessment,” LILA, -“human-made tree islands.” This research will eventually help recreate the many areas that have lost their tree islands. 2. Water Conservation Area 2

WCA 2 has experienced high phosphors and nitrogen levels going back to the 1960s. We could see the impaired landscape as we entered WCA2. The vegetation really started to change. The tree islands were no longer visible as the nutrient pollution has altered the flora and fauna. This is what happens when loads of phosphorus and nitrogen from agriculture and developed areas flows through pristine areas. They are lost, but there is hope…

-Leaving Water Conservation Area 1, going over the Hillsboro Canal into Water Conservation Area 2. Note vegetation changes compared to WCA1. -Hillsboro Canal-Note lack of tree islands. The vegetation has gotten so thick and tight Mark Cook says even an alligator cannot push though. There are many plants but mostly cattail, sawgrass, and willow. Dr Cook explained a program entitled “Cattail Habitat Improvement Project” or CHIP.

He showed us -large rectangles-cut into the thick vegetation. This was done a an experiment and is showing to be quite successful. Mark said just a few weeks prior, the birds were “going crazy” feeding here. These cuts-outs become “pools of life!” You can see them below.

-Thick vegetation WCA2 -CHIP- the wildlife and birds do return to these areas were vegetation has been cut out and improved. This gives hope for the future of WCA 2. 3. Water Conservation Area 3

Next we crossed the North New River Canal entering gigantic Water Conservation Area 3.

Here the lands are also impaired due to pollution but not as much as Water Conservation Area 2. One can still view here the Ridge and Slough that made up just about all south of the sawgrass prairie that today is the Everglades Agricultural Area.

-Note the small white specks – birds on giant tree island-A side view-Further west in WCA 3 – very clear Ridge and Slough pattern -Further Southwest above the Tamiami Trail – cypress domes and cypress forest. So pretty! -Juvenile birds feeding away from their nests

4. Everglades National Park – below the Tamaimi Trail. Dr Cook said the green in the water is water lettuce.

-This handout from earlier in the year shows the areas of the greatest bird nesting (red ovals and stars). Look at the numbers!

Final words of Dr Mark Cook

“This morning I completed my last survey of the breeding season and I’m excited to report that pretty much every nest in the Everglades (all 80k of them) has now fledged. Despite the start of the rains and the increased water levels there are still thousands of foraging birds in the freshwater marshes and along the coast meaning that the Everglades is still affording the young birds plenty of foraging opportunities which is critical at this early stage of life. The photo is part of a large flock of ibis in the western marl prairies of #evergladesnationalpark -“

-Dr Mark Cook, Facebook, 6-25-21

Thank you for JK for a very smooth flight!

At Our Front Door

My husband Ed took up the Baron today. His aerials are a potent reminder that even though the water has been looking “great” near the Sandbar in the St Lucie River/IndianRiver Lagoon, there is algae literally at “our front door.”

-Structure 308 at Port Mayaca, Lake Okeechobee 6-15-21, 1:18 pm -all photos Ed Lippisch-Just west of S-308 at Port Mayaca, Lake Okeechobee-North of S-308 at Port Mayaca, Lake Okeechobee along Rim Canal-Lake Okeechobee north of Port MayacaSt Luice River/Indian River Lagoon residents have been fortunate that the ACOE, due to the presence of algae, made decisions this 2021 not to discharge as much to the St Lucie. This began on April 19, 2021 when the ACOE S-308 “Sediment Study” was postponed due to high levels of cyanobacteria in the toxic blue-green algae at the S-308 gate. The HAB DEVIATION the ACOE had put in place made this possible.

Looking broadly, my brother Todd’s website EyeOnLakeO shows that although cloudiness has made satellite images difficult, the majority of the algae in Lake Okeechobee is presently on the west side, and the Caloosahatchee, unlike the St Lucie, has to take water to to maintain salinity levels. Thus they have algae in their river system right now.

As I sit here, rain is pouring down. We know dry season is over and rainy season has begun. What is critical is that the ACOE does not open S-308 and S-80 this year as our seagrass beds are just starting to recover after years of Lake O discharges. S-80 is the gatekeeper for the St Lucie River/Indian River Lagoon. For now, S-80 is closed. In order to keep it closed for 2021 please write the ACOE at:

SFWMD canal and basin map. C-44 canal is the canal most southerly in the image, note S-308 and S-80.

-S-80, St Lucie Locks and Dam now closedI am very pleased that Lake Okeechobee’s level is down to 12.50 feet; however, we know that could change quickly due to hurricane season. We must remain vigilant.

In closing, I want to share one cool thing that happened during Ed’s flight the thad nothing to do with algae. He saw the Goodyear Blimp!

Thank you Ed for continuing to be our “eye in the sky” since 2013! To view the SFWMD’s most recent comprehensive Ecological Report click here. There is a lot more to the system than us! 🙂
