Coexisting with Alligators is Possible

/in ,

Alligators have inhabited Florida’s marshes, swamps, rivers and lakes for many centuries. They can be found in all 67 counties. Current populations are estimated at 1.3 million alligators in Florida.

In recent years, Florida has experienced an increase of new residents and tourism. Many residents seek waterfront homes, and increasingly participate in water-related activities. This can result in more frequent alligator to human interactions, and a greater potential for conflict. While serious injuries caused by alligators are rare in Florida, the Florida Fish and Wildlife Conservation Commission (FWC) offers the following tips about how to safely coexist with them:

  • Be mindful that April is the beginning of breeding season for alligators, and they may be more aggressive during this period.
  • Keep a safe distance if you see an alligator and never feed one. When fed, alligators can lose their natural wariness and instead learn to associate people with the availability of food.
  • Swim only in designated swimming areas during daylight hours. Alligators are most active between dusk and dawn.
  • Keep pets on a leash and away from the water’s edge, and never let them swim in fresh or brackish water. Pets often resemble alligators’ natural prey.
  • If you want to keep alligators out of your yard, install a fence that is at least four and a half feet tall. Alligators are good climbers and anything lower would not be adequate protection.

It is illegal to kill or harass alligators in Florida and may only be hunted under special licenses and permits. The FWC places the highest priority on public safety and administers a Statewide Nuisance Alligator Program to proactively address alligator threats in urban areas, while conserving alligators in areas where they naturally occur. If you are concerned about an alligator, call FWC’s toll-free Nuisance Alligator Hotline at 866-392-4286. The FWC will dispatch one of its contracted nuisance alligator trappers to resolve the situation.

The Orrin Randolph Plan

/in ,

The Lake Worth Drainage District (LWDD) was established on June 15, 1915, with a three-member Board of Supervisors whose mission was to reclaim land within its boundaries. Prior to the creation of LWDD, a considerable amount of drainage work had already been completed by several entities such as the State of Florida, the Palm Beach Farms Land Company, the Model Land Company, and the Boston & Florida Atlantic Coast Land Company. In addition, private landowners and farmers had dredged drainage canals throughout the area. Although small drainage systems had been created, a cohesive long-term drainage plan was needed for the future expansion of what is now known as Palm Beach County.

In the spring of 1916, Orrin Randolph, Chief Engineer for the newly created LWDD, presented his first report to the Board of Supervisors. This report contained 127 pages detailing a plan of means and methods for draining the lands within the boundaries of LWDD. The report was submitted in compliance with Chapter 6458 of the 1913 Session Laws of the State of Florida. At that time, LWDD consisted of 129,317 acres of land and 3,400 acres of water. Rectangular in shape, LWDD extended 26 miles in length and 8 miles in width. Population records of 1916 showed there were approximately 6,500 owners of property within LWDD’s boundary making the average ownership equal to 20 acres per capita. Approximately 400 farmers were cultivating an estimated 5,000 acres of land, principally vegetables for distribution to northern markets.

In his report, Orrin Randolph identified the areas within LWDD that could not safely be relied upon for agricultural purposes and outlined the design parameters needed for future drainage. Randolph stated, “Provisions for artificial drainage would absolutely be necessary in order to provide a run-off rapid enough to prevent the destruction of crops as a result of accumulated excess water on the land.” Thus, Randolph’s extensive report was adopted by the Board of Supervisors as the Plan of Reclamation. The implementation of this plan would forever change the local landscape.

South Florida’s abundant agricultural resources served as the catalyst upon which prosperous and populous cities were built. This prosperity, then and now, is a result of the water management plan introduced by Orrin Randolph and adopted by LWDD over a century ago as the Plan of Reclamation. This plan created a large network of drainage canals providing flood control and water supply which remarkably still functions today for over 800,000 residents and tens of thousands of acres of farmland.

Agriculture in our area no longer exists to only feed the local inhabitants, and the migration of people into Florida continues to increase annually. LWDD has modified its mission over the century to meet the changing water management needs of these two diverse communities. Much of the District’s emphasis today is on residential flood protection. Although meeting the needs of agriculture and settlement can bring many challenges, it is because they harmoniously co-exist that living and working in our community is so highly desirable.

Not All Algal Blooms Are Harmful

/in ,

Warm temperatures and rainy Summer weather conditions often set the stage for algal blooms in our rivers, lakes, ponds, and canals. Like many people across the State, residents of the Lake Worth Drainage District (LWDD) may have concerns or confusion about these blooms. To help answer some frequently asked questions, we are providing the following information about algae.

Algae are simple organisms that grow through photosynthesis, a process by which sunlight is used to metabolize nutrients. Algae are a basic component of the food chain and are commonly found in marine, estuarine, freshwater lakes, canal systems, stormwater ponds and even swimming pools. Algae appear as green, red, or yellowish-brown particles that float on the water surface.

Although algae are a normal component of an aquatic ecosystem, nutrient-rich waters warmed by the sun provide a favorable medium for the overgrowth. This overgrowth is called an ‘algal bloom’. For algal blooms to occur two things must be present: high concentration of nutrients (nitrogen and phosphorus) and adequate sunlight. We cannot control sunlight, but we can limit our nutrient impact to surrounding waterbodies with proper maintenance of septic tank systems and limited use of fertilizers on landscapes and lawns. Currently approved herbicide or chemical treatments for the removal of algae uses a heavy metal compound that may adversely impact the waterbody. However, scientists are studying new treatments for the control of algae and safer alternatives may become available in the future.

While visually unappealing, most algae is not harmful to human health and provides a food source for aquatic life. However, some types, like “Blue-green” algae, which is a cyanobacteria, secrete toxins that may be harmful. The algae toxins can be inhaled by people living around the waterbody. It will aggravate respiratory illnesses like asthma. Symptoms of exposure to toxic algae include difficulty breathing, wheezing, skin rashes, headaches, and possible tingling in the fingers and toes. If water containing toxic algae is consumed potential liver damage may occur. It is important to keep humans and pets away from waterbodies that have toxic algal blooms and seek medical advice if symptoms appear.

Since most types of algae found within LWDD’s canals are non-toxic and do not impact flood control operations, LWDD does not regularly treat the canal system for algal blooms. Most algae growth in our canals is harmless and will dissipate on its own or will be flushed out of the canal system after a heavy rainfall.

How Flood Control Works

/in , ,

Man-made stormwater ponds are attractive enhancements to many residential communities and businesses within the Lake Worth Drainage District (LWDD). More importantly, these waterbodies serve an important public safety purpose as they are part of the overall flood control system.

When it rains stormwater flows into the retention pond and, if needed for flood control, out through the pond’s discharge control structure into the LWDD canal. Most of the time this drainage occurs unnoticed by the average individual. However, during a severe storm, flooding in streets, sidewalks, and driveways may occur. This temporary flooding may cause concern, but it is important to note these low-lying areas are designed as secondary detention areas to protect buildings and homes from flooding.

Within LWDD’s boundary, flood control is a shared responsibility and achieved through an interconnected, 3-tiered drainage system governed by 3 unique groups of people. Through communication and coordination, these 3 groups can provide effective flood control. The groups are identified as:

  • Neighborhood drainage systems operated by property owners or residential associations
  • Secondary drainage systems operated by LWDD or municipalities
  • Primary regional 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. The inspection of control structures, pumps and other infrastructure is also conducted, and repairs or replacements are made.

Property owners and residential associations have a similar role regarding their neighborhood drainage system. They must maintain their drainage infrastructure to ensure that inlets, storm drains, underground pipes, and emergency 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 the drainage infrastructure should be made, and repairs should be completed before the onset of storm season.

LWDD works closely with property managers and community boards to manage potential flooding. You can find more information about flood control at https://lwddnet.wpengine.com/storm-response.
