Man-made lakes and ponds are attractive enhancements to many residential communities and businesses within the Lake Worth Drainage District (LWDD). More importantly, they serve an important public safety purpose by providing stormwater storage for flood control.
When lake elevations rise due to rainfall, excess stormwater will flow through the community’s discharge control structure and into the LWDD canal. Most of this drainage occurs unnoticed by the average individual. However, during a severe storm, flooding in streets, sidewalks, and driveways may occur. This nuisance flooding may cause concern for some residents. However, these low-lying areas are designed as secondary detention areas to protect homes from flooding.
Within LWDD, flood control is a shared responsibility and achieved through an interconnected, three-tiered drainage system. By working together, these three systems provide effective flood control. This three-tiered system is made up of:
- tertiary, or neighborhood drainage systems operated by property owners or residential associations
- secondary drainage systems which are operated by LWDD
- the primary system operated by the South Florida Water Management District
Water managers in charge of primary and secondary systems are continually monitoring the weather and canal levels to proactively respond to changes in canal elevations. In anticipation of a heavy rainfall event, water managers will make operational adjustments to maintain appropriate water elevations for flood control. Additionally, throughout the year, routine canal maintenance is conducted to provide unobstructed flow in the canal channel and access along the canal rights-of-way.
Property owners and residential associations have similar role. They must maintain their drainage infrastructure to ensure that inlets, pipes, and discharge control structures are free of potential blockages and working as designed, thus maintaining the flow of stormwater away from their property. An annual inspection of drainage infrastructure should be made, and repairs should be completed before the start of storm season on June 1.
The likelihood of flooding depends on several variables such as rainfall volume, duration, ground moisture, and local terrain. It is important to note that flood protection does not mean flood proof. No system, no matter how well designed, is 100% flood proof. Even with quality flood control, homes and businesses may experience flooding if rainfall exceeds the drainage design or stormwater flow is blocked by debris.

Before, During And After The Storm
/in Hurricanes, NewsFlorida’s hurricane season begins on June 1 and ends November 30. Based on historical weather records dating back to the 1950s, a typical season will average 12 tropical storms with sustained winds of at least 39 miles per hour, of which six may turn into hurricanes with winds of 74 miles per hour or more. In addition to high winds, hurricanes and tropical storms can bring torrential rainfall. These severe weather events can produce localized flooding that can be exacerbated by improperly maintained drainage systems.
Residential communities and businesses can help mitigate the impacts of severe storms with a few simple steps. One of the most important steps is the regular inspection and maintenance of drainage infrastructure. Drainage infrastructure can include inlets, discharge control structures, connecting pipes, and lakes. Proper maintenance of these facilities will ensure the unobstructed flow of stormwater and fully operational equipment. Secondly, residential communities and businesses with operable discharge control structures can request authorization from the Lake Worth Drainage District to open these structures prior to the storm. Lowering lake levels provides additional storage for excess stormwater. The Lake Worth Drainage District recommends the establishment of a Drainage Committee whose role is to provide for the maintenance and operation of the community or business’ drainage system. Drainage Committees may consist of board members, residents and/or property managers. All members of the Drainage Committee should register with the Lake Worth Drainage District on its website at www.lwdd.net. This registration process ensures the Lake Worth Drainage District knows who to contact and where to send important weather alerts and instructions.
During the storm event, follow emergency management instructions via the television or radio and take appropriate actions to keep yourself, family and property safe. In most circumstances, emergency personnel will not be deployed during the weather event. Depending on the volume and duration of rainfall, expect streets, sidewalks, driveways, and lawns to flood. These areas are designed to act as secondary detention areas and help to keep water away from homes and businesses. This flooding is temporary and will begin to recede after an event has passed. District personnel will be monitoring canal elevations and making operational adjustments to major flood control structures. This work can be conducted during the storm via wireless mobile devices and provide instantaneous response to changes in water elevations.
It may be tempting to explore outside but stay indoors after the storm. For your safety and to keep roadways clear for emergency response vehicles, stay inside until told otherwise by authorities. Do not attempt to walk in flooded areas. Flood water may be unsanitary and there may be downed power lines or other hazards that are not visible. Do not attempt to drive through flooded areas. Vehicles can become unstable and float in as little as a few inches of water. Additionally, canal banks may fail, and roadways may be affected by sinkholes. The location of roads and sidewalks may not be discernible from canals and lakes and life-threatening accidents can occur.
While weather predictions are becoming more sophisticated, forecasters are still unable to predict exactly where a storm will make landfall. The likelihood of flooding depends on several variables such as rainfall volume, ground moisture, and local terrain. No system, no matter how well designed, is 100% flood proof but working closely with communities, businesses and other water management agencies, LWDD can help keep you and your property safe from potential flooding.
Lake Okeechobee Water Management
/in Drought, Flood Control, News, O & M, Water ConservationAt its meeting on April 19, 2019, the LWDD Board of Supervisors unanimously adopted Resolution 19-04 urging the U.S. Army Corps of Engineers (USACE) and the South Florida Water Management District (SFWMD) to consider the importance of protecting Palm Beach County’s water supply in the development of a new Lake Okeechobee regulation schedule.
Lake Okeechobee is part of an integrated regional water management system essential to communities, businesses, public water supply utilities and ecosystems throughout Palm Beach County. The U.S. Army Corps of Engineers (USACE) manages Lake Okeechobee water levels. The USACE is in the process of developing a new Lake Okeechobee water level regulation schedule called the Lake Okeechobee System Operating Manual (LOSOM) which will define the parameters for future management of Lake Okeechobee.
The LWDD is highly dependent on Lake Okeechobee as a source of water supply, especially during times of water shortages. As the new LOSOM is developed, LWDD urges the USACE and the South Florida Water Management District (SFWMD) to favor operational alternatives that maximize health, safety, and welfare of the water-use community. The future operational design for Lake Okeechobee should include changes that minimize the potential for short-term water supply shortages, and protect the existing permitted water allocations, which will assure the predictability of a continued and reliable source that is essential to water supply planning on local and regional levels.
The LWDD recognizes that water supply is but one of the significant public health, safety and welfare concerns that must be weighed by the USACE and SFWMD in the development of LOSOM. These include the environmental health of the Lake, the health of flora and fauna which make Lake Okeechobee home, the health of the Everglades, the health of the Caloosahatchee and St. Lucie Estuaries, and the integrity of the Herbert Hoover Dike and safety of surrounding communities.
The Lake Worth Drainage District (LWDD) provides flood control and water supply for more than 800,000 residents and more than 10,000 acres of agricultural land in Palm Beach County. The LWDD service area encompasses 218 square miles, with 13 municipalities and 511 miles of drainage canals. Additionally, LWDD water control activities provide aquifer recharge to prevent saltwater intrusion for numerous major wellfields.

Alligators In Your Backyard
/in NewsThe Lake Worth Drainage District (LWDD) canals and rights-of-way are abundant with wildlife even in urbanized areas. Residents may encounter various species living in and around the canal system. Most of the animals are harmless. Some can become a nuisance to residents like Muscovy ducks, raccoons, and iguanas. However, some animals are dangerous and even life-threatening like alligators and some types of snakes.
The Alligator is a particularly dangerous animal in a residential area. An estimated 1.3 million alligators inhabit all 67 counties in Florida and can be found anywhere there is standing water. While alligators and people usually coexist peacefully, there have been recorded attacks and occasional fatalities. The key to staying safe is being alert to the possibility of an alligator’s presence.
Be cautious and assume that drainage canals and lakes are home to alligators. Do not swim or wade in areas where alligators are likely to inhabit, especially at dusk or night when they naturally feed. It is important to keep children away from the water’s edge and does not allow family pets to swim or explore waters if you are unsure about the wildlife inhabiting the waterbody. Feeding alligators in Florida are illegal. When people feed alligators, they lose their natural fear of people and associate humans with food.
Alligators are an important part of Florida’s ecosystem, but should always be regarded with caution. Aggressive alligators can be reported to the Florida Fish and Wildlife Commission’s Statewide Nuisance Alligator Program at 866-392-4286.
