About Herbert Hoover Dike

Herbert Hoover Dike (HHD) is a 143-mile earthen dam that surrounds Lake Okeechobee, the heart of the Kissimmee-Okeechobee-Everglades system.  The project reduces impacts from flooding as a result of high lake levels for a large area of south Florida.

Since 2007, the Corps has made a significant investment, over $500 million, in projects designed to reduce the risk of catastrophic failure of the aging structure. Actions taken include installing a partial cutoff wall, removing and replacing water control structures (culverts), and conducting a variety of studies and technical reviews to help ensure the safety of south Florida residents. Corps teams work daily on the dike, providing contractor oversight, quality assurance, inspections, and dike operations and maintenance. Much progress is also being made behind the scenes at the District, where a team of engineers, hydrologists, geologists, scientists, contract and real estate specialists, budget analysts, and many others, work to ensure the very best rehabilitation strategies are applied to the dike today and in the future.

The HHD Project team maintains close coordination and communication with other internal Jacksonville technical offices such as Engineering, Planning, Contracting, Corporate Communication, Construction and Operations while maintaining a presence (HHD Project Manager forward) in the local project area to communicate regularly with local communities and the construction field offices regarding project updates and problem solving.

Environmental report on proposed dike repairs available for 60-day public and agency review


The U.S. Army Corps of Engineers Jacksonville District has released a draft environmental report for public review on its proposal for additional embankment repairs on Herbert Hoover Dike surrounding Lake Okeechobee.Comments will be accepted through Feb. 23, 2016.

The report, known as Herbert Hoover Dike (HHD) Dam Safety Modification Study Draft Environmental Impact Statement focuses on a tentatively selected plan to extend embankment repairs over 28 miles on the south and west sides of the structure. 

The proposed repairs include installing 24 miles of seepage barrier, commonly known as a partial cutoff wall from Moore Haven to Lake Harbor.  The Corps proposes installing an additional four miles of cutoff wall near Lakeport.  Engineers also recommend armoring the embankment around the State Route 78 bridge near the Harney Pond Canal and installing floodwall near water control structures on the Harney Pond and Indian Prairie Canals.

Comments will be accepted through Feb. 23, 2016, and can be sent electronically to: HHDEnvironment@usace.army.mil, or mailed to:

Background

The first embankments around Lake Okeechobee were constructed by local interest from sand and muck, circa 1915. Hurricane tides overtopped the original embankments in 1926 and 1928, resulting in over 2,500 deaths.

The River and Harbor Act of 1930 authorized the construction of 67.8 miles of levee along the south shore of the lake and 15.7 miles along the north shore. The U. S. Army Corps of Engineers constructed the levees between 1932 and 1938.

A major hurricane in 1947 prompted the need for additional flood and storm damage reduction work. As a result, Congress passed the Flood Control Act of 1948 authorizing the first phase of the Central and South Florida (C&SF) Project, a comprehensive plan to provide flood and storm damage reduction and other water control benefits in central & south Florida. The new dike system was completed in the late 1960’s and named the Herbert Hoover Dike.

The dike system consists of 143 miles of levee, hurricane gates and other water control structures.
