Stormwater 101: Frequently Asked Questions

Q.   Where does the water in the LWDD canals come from?

A.   Stormwater (rainfall) is where LWDD receives most of its water supply for the canal system. However, during dry periods with low rainfall, LWDD may rely on the regional system of canals, Water Conservation Areas and sometimes Lake Okeechobee as a source of supplemental water.

Q.   Who owns the water within LWDD’s canals?

A.   In Florida, water is not a property right but rather a resource ‘shared in common’ by landowners. Groundwater and surface water (canals) are held in trust for the benefit of its citizens. Ownership of the land adjacent to a water body does not provide ownership of the water nor the right to use the water. The right to use water is regulated by the State of Florida through regional water management districts. In our area, the entity responsible is the South Florida Water Management District.

Q.   What is a drought?

A.   While it is relatively easy to define what a hurricane or an earthquake is, defining a drought is more subjective. Droughts do not have the immediate effects of floods, but sustained droughts can cause economic stress throughout an area. The word “drought” has various meanings, depending on a person’s perspective. To a farmer, a drought is a period of moisture deficiency that affects the crops under cultivation. Even two weeks without rainfall can stress many crops during certain periods of the growing cycle. To a meteorologist, a drought is a prolonged period when precipitation is less than normal. To a water manager, a drought is a deficiency in the water supply that affects water availability and water quality.

Q.   How does drought affect private and municipal well fields?

A.   The water level in the underground aquifer that supplies a well does not always remain the same. Seasonal variations in rainfall or manual pumping may affect the height of the underground water levels. If a well is pumped at a faster rate than the aquifer is recharged by rainfall or other underground water flows, then the water level in the well can be lowered. This can happen during drought, due to the deficit in the amount of rain.

Q.   Where can I find information about water restrictions in my area?

A.  To promote responsible water use and protect our valuable water resources, Palm Beach County observes the South Florida Water Management District’s Year-Round Landscape Irrigation Conservation Measures Rule. Landscape irrigation is restricted to three days a week before 10 a.m. or after 4 p.m. Several municipalities within the Lake Worth Drainage District’s jurisdictional boundaries have adopted their own, more stringent water and irrigation conservation ordinances. Please check with your local municipality for their specific water use rules. For additional information on current water restrictions, visit the South Florida Water Management District’s website at

Flood Control Checkup

Throughout the year, the Lake Worth Drainage District (LWDD) oversees the operation and maintenance of approximately 500 miles of canals and 1,000 miles of canal rights-of-way. In addition, LWDD operates 20 major water control structures which release or hold back water depending on conditions. However, effective flood control takes more than just LWDD. Property owners and residential communities all have a role to play in the overall flood control system.

In South Florida, flood control is a shared responsibility and is achieved through an interconnected, three-tiered drainage system. 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, county or municipalities, and the primary system operated by the South Florida Water Management District (SFWMD).

The role of property owners and residential associations is similar to LWDD in that they retain stormwater onsite in retention ponds/lakes for water quality purposes and discharge excess stormwater for flood control. They must maintain their drainage infrastructure to ensure that inlets, pipes and discharge control structures are working as designed.

South Florida’s dry season runs from approximately November through May. January is the ideal time of year to conduct inspections of drainage infrastructure and make any necessary repairs. Additionally, the start of a new year is when many residential boards hold elections and change property management companies. It is important to register these changes with LWDD to ensure the correct individuals are receiving important weather alerts and flood control instructions. Taking time during the dry season will help ensure that your property is ready for the coming rainy season.

Dry Season Landscapes

Water is a critical factor for healthy and attractive landscapes. The absence of adequate rainfall or irrigation can lead to drought stress and reduced plant growth. Drought stress happens when the plant’s roots cannot absorb the quantity of water needed to support normal growth processes. Even though South Florida receives an annual average of over 50 inches of rain, this rainfall is seasonal. Some plant species encounter drought stress during our dry season which lasts from approximately November to May.

During times of reduced water, plants react by cutting down on photosynthesis and other processes to reduce their water consumption. With progressive water loss, the leaves of some plant species may turn pale or brown. Foliage often withers away, and the entire plant may die. This can be a frustrating and a costly occurrence for a home gardener. So why fight mother nature? There are hundreds of landscape plants that can tolerate drought stress. A few familiar to most gardeners are the Blanket Flower with bright gold and red flowers, Firebush with colorful tube-shaped yellow-and-orange flowers and Buttonwood which can be used as an attractive hedge. Many drought-tolerant flowering plants are a favorite among butterflies and hummingbirds which can add more beauty to your landscape.

Creating a landscape design using drought-tolerant shrubs, trees and flowers can help you avoid plant loss and extensive water-use. For more information on drought-tolerant landscapes, visit the University of Florida’s website at

Making Holidays Happier For Kids

Giving back to the community is important to LWDD. This year staff collected gifts for the non-profit Spirit of Giving Network’s Annual Holiday Gift Drive. The Spirit of Giving Network, in partnership with the Junior League of Boca Raton, works with organizations to help make holiday wishes come true for children in Palm Beach County.
