Herbert Hoover Dke s an earthen embankment system located along the permeter of Lake Okeechobee, a large (724 square mle surface area) freshwater lake n south Florda. The lake s located about 30 mles west of the Atlantc Ocean and 60 mles east of the Gulf of Mexco. The lake and surroundng dranage area encompass approxmately 5,600 square mles. The dke was constructed prmarly to provde local flood protecton. Components of the embankment system have been bult ntermttently snce the early 1900 s. Federal nvolvement began n the 1930 s wth the constructon of dkes (for flood protecton) along portons of the north and south shores. 2

7 In the 1960 s, the crest elevatons of those dkes were ncreased and addtonal embankments were constructed on the northwest and northeast shores. As a result, the Herbert Hoover Dke system now encrcles Lake Okeechobee entrely, except n the vcnty of Fsheatng Creek on the western shore. The exstng embankments total about 143 mles n length wth crest elevatons rangng from 32 to 46 feet, Natonal Geodetc Vertcal Datum (NGVD). Adjacent land elevatons typcally range from 10 to 20 feet, NGVD. Lakesde levee slopes vary from 1V:3H to 1V:10H and landsde slopes range from 1:2 to 1:5. The Herbert Hoover Dke Major Rehabltaton Report (MRR) from 2000 dvded the 143 mle dke nto eght (8) Reaches wth the ntal focus on Reach 1. Ths Reach by Reach approach has been replaced wth a system wde rsk reducton approach as utlzed for USACE safety modfcatons to dams. The mplementaton of the 21.4 mle cutoff wall component n Reach 1 satsfes the majorty of the rsk reducton goals. The constructon of ths cutoff wall wll be complete n As part of ths rsk reducton approach, the 32 water control structures (culverts) operated by the Corps are beng replaced, removed or abandoned based on USACE approval n May One structure has been removed and four structures are currently under contract for replacement. Project nformaton, vdeos, pctures and fact sheets can be vewed at the followng Jacksonvlle Dstrct nternet ste.

Ths Reach by Reach approach has been replaced wth a system wde rsk reducton approach as utlzed for USACE safety modfcatons to dams. The mplementaton of the cutoff wall component n Reach 1 and the water control structure (culvert) replacements and removals around Lake Okeechobee satsfy the majorty of the rsk reducton goals for these areas. The goal of the project s to satsfactorly reduce rsks thereby lowerng the current DSAC I ratng.

18 LAKE OKEECHOBEE Herbert Hoover Dke FACTS & INFORMATION SPRING 2012 Lake Okeechobee, the naton s second largest freshwater lake and the largest lake n Florda s the heart of the Kssmmee- Okeechobee-Everglades system. The orgnal lake was lkely flled wth salt water, whch was eventually replaced by freshwater from ranfall. Water flowed from the Kssmmee basn nto Lake Okeechobee. Today, the lake provdes drnkng water for communtes around the lake and to the more than 6 mllon people lvng along the lower east coast. It serves as a source of rrgaton for a $1.5 bllon-a-year agrcultural ndustry that produces sugar cane, wnter vegetables, ctrus and rce. HISTORICAL BACKGROUND In the early 1900s, local governments and resdents bult up the lake s natural embankments wth sand, shell, muck and marl. By 1927, sx large dranage canals and numerous smaller canals totalng 440 mles had been constructed. Despte these actons, hurrcane wnds n 1926 and 1928 caused the lake s waters to quckly overwhelm ts shallow edge. Ths flow resulted n massve floodng and the loss of many lves. To help prevent a repeat of ths type of dsaster, the U.S. Army Corps of Engneers (Corps) was asked by Congress to buld a taller dke. It would protect the areas from Port Mayaca to Moore Haven and from the Kssmmee Rver to Nubbn Slough. In 1947 and 1948, two more hurrcanes passed drectly over Lake Okeechobee, causng massve floodng. Although the levees had done ther job n that no lves were lost, the need for better flood protecton was evdent. To ncrease protecton of peoples lves, ther property and the prosperous agrcultural ndustry located south of the lake, the Corps enhanced the exstng levees. Completely encrclng the lake and rasng the exstng levees, one of the levee s prmary purposes was to provde protecton durng severe hurrcanes. In 1960, Congress named the levee Herbert Hoover Dke (HHD). THE DIKE The Corps bult the dke wth gravel, rock, lmestone, sand and shell usng state-of-the-art engneerng n the 1930s. These natural materals allow water to trckle through at tmes. Ths s a normal process called seepage. When the water level n the lake s too hgh, however, the water pressure causes extra seepage that can lead to eroson, or ppng. When the water level s too low, the sol dres out and that changes the makeup wthn the structure and foundaton. Nether extreme s good, so engneers closely montor the lake levels and the dke. The Corps wll remove or replace all federal culverts n the dke system.

19 LAKE OKEECHOBEE Herbert Hoover Dke MAKING IT BETTER AND STRONGER Managng and Montorng Lake Okeechobee and Herbert Hoover Dke Together, the Corps and the South Florda Water Management Dstrct manage the lake accordng to a regulaton schedule. The schedule allows the Corps to manage the lake at a safe level at the begnnng of the wet, hurrcane season to allow for more capacty or a hgher lake level by the end of the wet season. The safe lake level helps provde storage capacty for wet season ranfall, whch n turn provdes water supples to the envronment and the people. The schedule has been developed over tme to meet the many demands for the lake s water. It also provdes water managers wth the authorty to determne when and n what amounts water s to be released from the lake. For the optmum health of the lake and use of ts water, water managers strve to mantan the levels between 12.5 and 15.5 feet, not too hgh and not too low. Past hurrcane seasons, however, created hgher than desrable water levels, rasng concerns about the stablty of the HHD n extreme weather condtons. Water levels and the condton of the dke are montored on a regular bass. Pror to a tropcal storm, the dke s nspected and outlets are closed untl after the storm. Once weather condtons permt, typcally wthn 24 to 48 hours after a storm, Corps personnel nspect the dke agan. Stored n dfferent areas around the lake are equpment, sandbags, stone, rock and other materals to expedte makng repars or strengthenng areas that may become eroded by the force of hurrcane-drven waves. Rgorous analyss has shown that a major rehabltaton of HHD s requred to prevent harmful seepage, whch could undermne the dke structure. The frst part of the rehabltaton currently underway, focuses on a secton of the dke that spans 22.4 mles from Port Mayaca to Belle Glade. The U.S. Army Corps of Engneers and the South Florda Water Management Dstrct are commtted to mantanng Florda s fragle balance between the needs of people and the conservaton of the state s unque wldlfe and water envronments. Herbert Hoover Dke plays an mportant role n helpng us to keep that commtment. FOR MORE INFORMATION EMERGENCY ACTION If a weakened dke condton s observed, the Corps wll actvate ts Emergency Acton Plan. The plan ncludes a formal notfcaton process that moves n rapd order from the federal government, to the state, to the county Emergency Operatons centers. The countes surroundng the lake would notfy resdents of any actons, such as evacuatons, that resdents should take. 701 San Marco Blvd. Jacksonvlle, FL US ARMY CORPS OF ENGINEERS

20 HERBERT HOOVER DIKE REHABILIATION PROJECT UPDATE SPRING 2012 Herbert Hoover Dke (HHD) s lsted as one of the naton s dams and ts rehabltaton s a top prorty of the U.S. Army Corps of Engneers. In the last fve years, the HHD Rehabltaton Project receved $56 mllon n 2008, $74 mllon n 2009, $124 mllon n 2010, and $107.8 mllon n 2011 ths represents a sgnfcant porton of Dam Safety fundng naton-wde. There are currently 10 dams n the naton recevng addtonal funds for constructon projects to reduce the rsk of falure; HHD s one of them. Jacksonvlle Dstrct s workng to rehabltate the 143-mle dke system. Actons taken nclude nstallng a cutoff wall, removng and replacng water control structures (culverts), testng landsde seepage management features and conductng a varety of studes and techncal revews to help ensure the safety of south Florda resdents. Corps teams work daly on the dke, provdng contractor oversght, qualty assurance, nspectons and dke operatons and mantenance. Much progress s also beng made behnd the scenes at the Dstrct, where a team of engneers, hydrologsts, geologsts, scentsts, contract and real estate specalsts, budget analysts and many others, work to ensure the very best rehabltaton strateges are appled to the dke today and n the future. Here s a progress update on the most sgnfcant components of the rehabltaton. OVERALL SYSTEMS APPROACH The Corps s approachng ths project utlzng a dam safety process that prortzes what can be done to lower the rsk across the entre HHD system. Work s underway to produce a Dam Safety Modfcaton (DSM) Report for HHD, whch wll address the entre dke as a system. It wll nclude a rsk reducton approach to mplementng features based on prorty and reducng rsk as quckly as possble. All features planned and under constructon support the goal of ths report. CUTOFF WALL CONSTRUCTION Constructon of the cutoff wall s provdng the soluton by elmnatng exstng ppng and preventng addtonal nternal eroson through the dke and foundaton. The Corps awarded multple task order contracts for cutoff wall constructon n the dke between Port Mayaca and Belle Glade to three contractors.to date, over 21 mles of cutoff wall n the southeast secton are under constructon or have been completed, totalng over $225 mllon n cutoff wall contracts.

21 HERBERT HOOVER DIKE REHABILIATION HHD CULVERT REMOVALS OR REPLACEMENTS Bult n the 1930s, most of these old culverts along the HHD are stll n use today. From a structural ntegrty perspectve, culverts pose a rsk of falure due to the loss of embankment materal nto and along the culverts. As part of the federal culvert replacement program, the Corps wll replace or remove 32 culverts wthn the HHD system. Work began n late 2011, wth the removal of Culvert 14 north of Canal Pont. Addtonal work began n 2012 to replace Culverts 11 and 16 south of Port Mayaca, and Culverts 1 and 1A east of Moore Haven. Contracts for the replacement of Culverts 3 and 4A near South Bay are expected to be awarded n the fall. The Corps antcpates removng or replacng all the culverts wth constructon contnung through A temporary dam s constructed n advance of the removal of Culvert #14 near Port Mayaca. The culvert was removed n the fall of (Photo courtesy of Optmum Servces, Inc) LANDSIDE FEATURES AND SEEPAGE MANAGEMENT PILOT TEST The Corps s plannng to mplement a plot test to dentfy potental alternate plans that stablze the dke for lower total project cost. Ths plot test wll be n two locatons on the southern embankment and demonstrate whether ths alternatve approach result n a more economcal rehabltaton plan wth less mpact on adjacent lands whle stll addressng the embankment and foundaton seepage and ppng concerns. The results of ths study wll also support the overall rsk reducton approach for the entre HHD system. FOR MORE INFORMATION 701 San Marco Blvd. Jacksonvlle, FL US ARMY CORPS OF ENGINEERS
