Lake Advisory EXTENDED for Lake Rowena

OCAlerts logo

Recent lab results from a sample collected by the City of Orlando at Lake Rowena indicate the continued presence of algae toxins in the water column.

As a result, Lake Rowena will continue to be closely monitored by the City and the Florida Department of Environmental Protection (FDEP) staff.

The FDEP may collect samples for analysis at a future date (possibly 4-6 weeks) determined by the FDEP for Lake Rowena and will provide updates on any possible detection of algae toxins as reported on the FDEP Algal Bloom Reporting dashboard.

At this time, the Lake Alert for Lake Rowena remains in effect until further notice.

Please continue to refrain from recreating on the lake, including swimming, fishing and boating.

LIFTED: Lake Alert for Lake Emerald

Based on the latest results obtained by city staff from sampling Lake Emerald on September 15, 2021, the Lake Alert for Lake Emerald has been lifted.

At this time, there are no toxins present in Lake Emerald, but blooms may still occur.

There are always risks that could be associated with swimming, recreating, or irrigating in and from water with algal blooms, please use your own caution.

If you see a visible bloom present, please report it to the FDEP Algal Bloom Dashboard, which can be found here: floridadep.gov/AlgalBloom.


Original Lake Alert:

On July 21, 2021 the Florida Department of Environmental Protection (FDEP) tested water samples from Lake Emerald and determined that potentially unsafe concentrations of microcystin (toxins) are present in the lake. As a precaution, we are advising everyone to refrain from swimming, recreating and irrigating in/from Lake Emerald until further notice.

For reference, cyanobacteria/blue-green algae are always present in the water, however, not all bacteria have the ability to produce toxins. Toxicity is hard to predict because a single species of algae can have toxic and non-toxic strains. Nothing can be done to treat algae blooms without causing massive fish kills. In the coming weeks, the city will work closely with Florida Department of Environmental Protection (FDEP) to monitor Lake Emerald. Once we obtain more information on the status of the lake, we will continue to update this Lake Alert.

Please encourage your neighbors to register for the Lake Alert at orlando.gov/lakealert so they too will get important information about Lake Emerald directly.

In the meantime, as we stated above, the city would advise refraining from swimming, recreating and irrigating in/from the lake until further notice.

Universal Orlando reducing water usage amid oxygen shortage

Faced with a potential citywide crisis, Universal Orlando, one of the Orlando Utilities Commission’s major customers, has cut back on cleaning, landscape irrigation and even dishwashing to save water.

The moves came after the city of Orlando and OUC asked residents and businesses to start conserving water in late August due to a pandemic-related shortage of liquid oxygen.

The resort reduced its overall water consumption by 38%, or nearly 1.3 million gallons daily, since OUC requested they conserve water Aug. 20, OUC spokesman Tim Trudell said. It is among OUC’s 10 largest commercial customers and the only theme park it supplies with drinking water.

Universal has started spot-cleaning parts of its theme parks instead of hosing down broad areas and reduced its potable water usage in irrigation, resort spokesman Tom Schroder said in an email.

The resort’s onsite hotels began using paper products in employee cafeterias to cut down on dishwashing, turned off potable water sprinklers and delayed pressure and window washing, he said.

Universal already employs an “aggressive” water conservation system between using recycled and repurified water in its rides and pools and reclaimed water for most of its irrigation, Schroder said.

Universal’s repurified water is processed using liquid chlorine, he said. The resort does not use liquid oxygen, which is employed in a higher-end treatment process for drinking water used less commonly than chlorine treatment systems.

Court vacates NWPR, is still weighing WOTUS restoration

A federal judge on Monday tossed out a Trump-era rule that rolled back water pollution protections, but is still weighing whether to restore Obama-era protections or simply undo the Trump rollback to return to pre-Obama regulations. In a court order, Judge Rosemary Márquez, an Obama appointee, vacated the Trump administration’s Navigable Waters Protection Rule (NWPR), which governed which bodies of water get protection from pollution. Márquez remanded the rule for reconsideration to the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers.

The Trump administration in 2019 repealed an Obama-era rule known as the Waters of the United States Rule, which expanded federal protections for smaller waterways.

And last year, the former administration put forward an additional rule, the NWPR, that reversed some protections, including for wetlands, that had been in place for decades.

The 2020 rule is the one that Márquez tossed and gave parties to a lawsuit challenging it 30 days to file proposals about what to do about the repeal rule.

The decision comes as the Biden administration seeks to revise the rule and asked the court to send the Trump rule back to it for reconsideration.

Sarasota County Red Tide Update, Aug. 31

Sarasota County Parks, Recreation and Natural Resources (PRNR) staff continue to monitor and assess public beaches and access points for seaweed accumulation and red tide impacts. See below for today’s conditions report:

TUESDAY, AUG. 31

Today, PRNR staff evaluated public beaches and access points, reporting mostly minor marine debris. Beach raking occurred on Venice Island and Siesta Key.

County staff continue to monitor and evaluate public beaches and access points each morning to determine if conditions meet the beach cleaning policy threshold. Regular beach combing take place Monday, Wednesday and Friday on Siesta Beach, and Thursday on Lido Beach.
