Lake Alerts

To address citizen concerns related to water quality, the Stormwater Section has developed a public information system, “Lake Alert,” to provide seasonal and localized warnings (and updates) for City of Orlando lakes. An announcement has been provided below regarding the lake(s) where water quality may currently be a concern.

February 14, 2018 – Lake Alert for Lake Beardall LIFTED

Please resume normal activities in this lake.

February 12, 2018 – Lake Alert for Lake Beardall

Type of water quality concern: Possible elevated fecal coliform counts due to a sanitary sewer overflow

Location: Long St, near the intersection of Grove Ave

Cause:  Blockage in sanitary line.

City Response:  City Water Reclamation staff stopped the overflow. Crews cleaned the sanitary lines and impacted areas. The impacted storm system was designed to contain a small volume of stormwater at all times. Approximately 2,400 gallons of sanitary waste and additional stormwater was removed from the stormline by City crews.  Warning Signs were placed around Lake Beardall.

The City is advising that water contact activities cease until further notice. City Stormwater personnel will collect bacteria samples, as a precaution. Once bacteria counts meet acceptable State Water Quality Standards, the Lake Alert Hotline number and the City’s Lake Alert website will be updated.

Public Notification – Please continue to call the Lake Alert number, 407.246.2220, for the most up-to-date information regarding your lake. During weekdays, the City’s Lake Alert website, www.cityoforlando.net/lakealert will also have the latest information.

For further information regarding the sewer discharge, please contact Athena Tipaldos, Water Reclamation Compliance Manager, at athena.tipaldos@cityoforlando.net.  For water quality questions, please contact Lisa Lotti, Stormwater Compliance Manager, at lisa.lotti@cityoforlando.net.


August 30, 2017 – Lake Alert Remains in Effect for Barker Park Canal (adjacent to Clear Lake)

Type of water quality concern: Possible elevated fecal coliform

Location: Canal bordering Barker Park. Impacted area identified between boat ramp and fishing pier.

Cause:  Undetermined

City Response:  City Stormwater personnel have been routinely sampling the canal for fecal coliform. Bacteria results meet State Water Standards in the area of the fishing piers and in the lake, but have exceeded State Water Quality Standards closest to the boat ramp. The City is actively investigating to determine the source that may be contributing to the elevated fecal coliform counts. Warning signs have been placed along the impacted portion of the canal.

As a health precaution, the City is advising that fishermen refrain using this portion of the canal until further notice.

For water quality questions, please contact Lisa Lotti, Stormwater Compliance Manager, at lisa.lotti@cityoforlando.net.

October 8, 2015 – Notice of City Activities Around Lake Silver

Staff from the City of Orlando and City contractors are installing equipment around Lake Silver to gather data about lake water quality and stormwater runoff.  Everyone associated with this work will carry proper identification, and you may ask to see that identification.  We will send you periodic updates as the project progresses.

For more information on this project, please visit reference the Lake Silver Fact Sheet or visit:  cityoforlando.net/streets-stormwater/silverlakenotice-of-city-activities/

If you have additional questions please contact Lisa Rain, Neighborhood Outreach Coordinator for Public Works, at lisa.rain@cityoforlando.net or call our Stormwater Hotline, 407.246.2370


What is a Lake Alert?

Lake Alerts are notifications posted, recorded or emailed when a City lake has a water quality concern. These notifications include the type of water quality hazard and severity of it. It also alerts the public when the water body is safe again for recreational purposes. Notifications will be posted on this page, recorded at 407.246.2220 and emailed to those who sign up to receive Lake Alerts in their inbox.


Avoid Naegleria fowleri and primary amoebic meningoencephalitis (PAM)

Parasitic disease caused by Naegleria is very rare — only a few hundred cases have ever been reported, however, a few common sense precautions will protect people from acquiring this and other water borne infections:

  • Avoid swimming in very warm water, especially if it is shallow and/or stagnant (not moving). The majority of PAM cases have resulted from exposure to water that is 26°C (80°F) or warmer.
  • Avoid taking in water through the nose while swimming, diving, water skiing or jumping into water. A nose clip can be used to prevent water being forced up the nose.
  • Stay out of the water if “No Swimming” signs are posted.
  • Do not swim in swimming pools that are very warm or that are not properly maintained, even if the water is chlorinated. Naegleria fowleri is resistant to chlorine.

Know the facts about health concerns related to blue-green algae exposure

Blue-green algae are simple plants that appear in water and wet areas. An algae “bloom” is a rapid buildup of algae that creates a green, blue-green or brown color on the surface of the water. They are often found in standing water in lakes and ponds near the shoreline. Warm, calm water and nutrients contribute to the rapid growth of algae. Blooms can occur any time of year, but are typically observed from the early spring to the fall in Central Florida.

Only a few types of blue-green algae are known to produce toxins, however, there is no way to determine visually whether or not a bloom is toxic. If you suspect an algae bloom is present, it is best to stay out of the water, keep pets away and contact the City of Orlando Stormwater Hotline at 407.246.2370. If you do contact the water, wash thoroughly with a clean source of water. Do not use the affected water for drinking or cooking, as toxins cannot be removed with filtration, boiling or chemical treatments. However, activities near the water are safe. Eating fish caught during a bloom can pose a health risk.

If swallowed, toxic algae can cause diarrhea, nausea, cramps, fainting, numbness, dizziness, tingling and paralysis. Skin contact can cause rashes or irritation. Children and pets are at greatest risk.

Characteristic images of algae blooms:


Appears as green paint spill on surface or appears as spongy green mat on surface.

The sanitary and stormwater sewers are two separate systems in the City of Orlando, meaning that stormwater enters natural waterways through storm drains, and sanitary sewage (wastewater) is transported for treatment to the wastewater plant. Despite this separation, following unusually heavy rainfall there is the potential for sanitary sewage overflow, which can carry bacteria from untreated sewage onto paved areas, into storm drains and into our lakes commonly used for recreational purposes.

In short, please delay your recreational activities at the lakes until 48 hours following an unusually heavy rainstorm, particularly those activities that involve people or pets entering the water directly or during which water could be swallowed (examples: jet skiing, water skiing or swimming). People who fish within the 48-hour window should wash their hands after touching the water. Anyone who wants to eat fish caught in the City lakes within the 48-hour window should cook them thoroughly to kill bacteria.

Why 48 hours? Over the 48 hours, lakes left standing without disturbance provides time for any bacteria to settle to the bottom, somewhat purifying the surface water.
