Rainy Season Readiness

Rainy Season Readiness graphicSouth Florida's annual rainy season typically lasts from June through October, a five-month period that brings 70 percent of our regional rainfall in an average year. The rainy season can also bring flooding, which may occur when large amounts of rain fall over a short period of time or from a single heavy storm, tropical system or hurricane.

Preparing Year-Round

If you haven't lived in Florida for long, you may not know that our climate has two seasons: wet and dry. Flood and drought are frequent visitors, the result of too much or too little rain. In any year, drought can happen during the wet season, and flooding can occur when we least expect a downpour. Weather in South Florida has a way of ignoring the calendar and expectations of "normal."

A Shared Responsibility

The South Florida Water Management District operates and maintains the regional water management system known as the Central and Southern Florida Project, which was authorized by Congress more than 60 years ago to protect residents and businesses from floods and droughts. This primary system of canals and natural waterways connects to community drainage districts and hundreds of smaller neighborhood systems to effectively manage floodwaters during heavy rain.

As a result of this interconnected drainage system, flood control in South Florida is a shared responsibility between the District, county and city governments, local drainage districts, homeowners associations and residents.

Map: Water Control Districts

Local canal systems in South Florida are maintained and operated by cities, counties and water control districts – also known as 298 districts for the chapter of Florida Statutes that outlines their responsibilities. These canal systems receive water from neighborhoods and store excess water or move it to the regional flood control system managed by the South Florida Water Management District.

More than 100 water control districts operate within the SFWMD's 16-county region. To see whether or not you live in a water control district, type your address into the search bar on the map below. If you do live in a water control district, the map will appear in a shaded color. Click anywhere in the shaded portion for your district's contact information and more details.


Managing Lake Okeechobee

At the heart of the greater Everglades ecosystem, Lake Okeechobee historically overflowed its banks, sending a sheet flow of water south through the Everglades. Today, the 730-square-mile lake is part of a massive flood control system known as the Central & Southern Florida Project, which stretches from just south of Orlando to Florida Bay and serves 8.1 million people.

The U.S. Army Corps of Engineers manages Lake Okeechobee water levels with the goal of balancing flood control, public safety, navigation, water supply and ecological health. The Corps bases operational decisions – whether to retain or release water in the massive lake – on its regulation schedule and the best available science and data provided by its staff and a variety of partners, including the South Florida Water Management District.

Lake Okeechobee Releases to Coastal Estuaries

In a fixed regional water management system with limited storage, the Corps must sometimes release water from Lake Okeechobee to the Caloosahatchee and St. Lucie rivers to protect public safety when lake levels get too high. more »
