  • Seepage beneath Hoover Dike southern shore of Lake Okeechobee, Florida

    Meyer, Frederick W. (Florida Geological Survey, 1971)
    Future water needs in southern Florida call for an increase in the storagecapacity of Lake Okeechobee. Seepage from the lake is expected to increase as aresult of raising the lake level. Data concerning the occurrence and amounts ofseepage are needed for the design and operation of flood-control works whichwill remove excess water from the rich agricultural lands along the southernshore. Intensive studies at five sites along the southern shore of LakeOkeechobee between the Caloosahatchee Canal and the St. Lucie Canal indicatethat seepage occurs chiefly through beds of shell and limestone which underliethe Hoover Dike at shallow depth. Seepage rates at the five sites range fromabout 0.1 to 0.9 cfs per mile per foot of head across the dike. Seepage beneaththe 50-mile length of dike should increase from about 22 to 50 cfs if the averagestage of the lake is raised from 14 to 16.5 feet. Seepage is greatest betweenMoore Haven and Clewiston, where deep borrows have been excavated on thelandward and lakeward sides of the dike. Most of the seepage from the lake canbe controlled by properly spaced toe ditches which would intercept the seepageand return it to the lake. (PDF contains 108 pages.)
  • Ground-water resources of the lower Hillsboro Canal area, Southeastern Florida

    McCoy, Henry J.; Hardee, Jack (Florida Geological Survey, 1970)
    This study was done to determine the amount and kinds of water beingproduced from the lower Hillsboro Canal Area in Palm Beach andBroward counties.All of the potable ground water being produced from theBiscayne aquifer is developed from the canal through infiltration.Rainfall in the area is the ultimate source for all of the water.Careful control and management will allow the development oflarge quantities of water from the canal toward Lake Okeechobee, buta fresh water head must be maintained along the contact of fresh waterwith sea water to prevent salt water intrusion.

  • Appraisal of water resources in the east central Florida region

    Lichtler, William F. (Florida Geological Survey, 1972)
    The rapidly expanding population and economic growth in the sevencounties of the East Central Florida Regional Planning Council as shown inFigure 1, herein called the East Central Florida Region or the Region, hasresulted in increasing demands on its water resources. Although there isabundant water in the Region as a whole, the water in some areas of the Regionis of unacceptable quality for most uses. As the population increases the demandfor water will become much greater and the available supply may be reduced bypollution and increased drainage necessitated by urbanization and other landdevelopment- Ground-water supplies can be increased by capturing and storingwater underground that now drains to the sea or evaporates from swamp areas.Research is needed, however, to develop artificial-recharge methods that arefeasible and which will preserve or improve the quality of water in the aquifer.(PDF contains 57 pages)
  • Ground-water resources of the Oakland Park area of eastern Broward County, Florida

    Sherwood, C. B. (Florida Geological Survey, 1959)
    The Oakland Park area obtains its water from the Biscayne aquifer,S composed of very permeable and porous, sandy limestones. The per-3 meability of the aquifer increases with depth, and wells in the area<\ generally obtain water at depths ranging from 60 to 80 feet, or betweenS 100 and 200 feet, depending on the quantity of water desired. Thedata presented in this paper can be used for further development ofwater and wise management of resources in the area. Large quantitiesS of ground water are still available at Oakland Park, if salt-water encroachmentcan be controlled. The data in this study provide the necessaryinformation to begin an effective water management program.(PDF has 49 pages)
  • Ground-water resources of Collier County, Florida

    McCoy, H. J. (Florida Geological Survey, 1962)
    The Biscayne Aquifer is the principal source of water for the heavilypopulated area in the vicinity of West Palm Beach and Miami. Thepublication of this data is timely and will assist in the intelligent developmentof the water resources of the area.The report recognizes two major aquifers as the source of groundwater in Collier County. The lower aquifer is highly mineralized, butcontains usable water, and the more shallow aquifer is the source oflarge supplies, which are utilized by municipalities and domestic users.Adequate supplies of fresh water are present in the Naples area and byproper planning, these can be developed in an orderly manner and saltwater encroachment can be prevented.(PDF has 99 pages)

  • Water available in canals and shallow sediments in St. Lucie County, Florida

    Bearden, H.W. (Florida Geological Survey, 1972)
    The increased demand for water placed upon the water resources ofSt. Lucie County by the expanding agricultural use has brought abouthydrologic changes with ensuing problems. This report documents thesechanges and provides data which are necessary in solving the problems. (PDF has 59 pages)
  • Hydrology of western Collier County, Florida

    McCoy, Jack (Florida Geological Survey, 1972)
    The U.S. GeologicalSurvey was requested in 1967 to locate areas that would most likelyyield the greatest quantities of the best quality water to satisfy theprojected municipal needs of western Collier County.The investigation included the following phases: (1) evaluationof existing data; (2) determination of the hydrologic and geologiccharacteristics of the subsurface materials; (3) collection of miscellaneousdischarge data in the inland canal complex and interpretationof the data; and (4) determination of the quality of water.

  • Reconnaissance of the geology and ground-water resources of Columbia County, Florida

    Meyer, Frederick W. (Florida Geological Survey, 1962)
    The Floridan aquifer was found to be principal source of groundwater in the area, containing artesian water in the northern part ofColumbia County, and being recharged in the southern part of thecounty. A few wells in the northern part of the county tap waterpresent in sediments that lie above the Floridan aquifer. Theseshallow waters are generally high in iron and tannic acid. Thedetails on the geology and hydrology necessary to conserve andutilize the water available to the residents of Columbia County arepresented in this study.(PDF contains 86 pages)

  • Evaluation of the quantity and quality of the water resources of Volusia County, Florida

    Knochenmus, Darwin D.; Beard, Michael E. (Florida Geological Survey, 1971)
    This report amplifies and refines some of the data alreadyissued covering the water resources of Volusia County, which were published asReport of Investigations No. 21. The work in the report was accomplished as acooperative program between the Department of Natural Resources, the U. S.Geological Survey and the Board of County Commissioners of Volusia County.Volusia County is almost totally dependent upon the water which falls upon thecounty and has a recharge area contained along the western portion and thecentral portions of the county. Excellent water is produced in the areal rechargeand it is anticipated that this data will expand the existing knowledge of thewater resources to permit the development of a great capacity for existingutilities and to offset and solve some of the problems now in the area.

  • Reconnaissance of the ground-water resources of the Fernandina area, Nassau County, Florida

    Leve, G. W. (Florida Geological Survey, 1961)
    Practically all water for municipal and industrial usein the Fernandina area is supplied by artesian wells. Inrecent years, the use of artesian water in the area has increasedto meet the needs of expanding industry and increasingpopulation. The total industrial and municipal pumpagehas increased from approximately 35 million gallons per dayin 1941 to approximately 50 million gallons per day in 1959.Correlated with the increase in water use is the constantdecline in the artesian pressure in the area. In many otherareas in Florida, such a decline in artesian pressure hasresulted in salt-water intrusion into the fresh-water supply.An intrusion of salt water in the Fernandina area would contaminatethe existing fresh-water supply and would resultin a hardship for the population and seriously injure theeconomy.Recognizing the threat to the fresh-water supplies ofthis area, the U. S. Geological Survey in cooperation withthe Florida Geological Surveymade a reconnaissance to determineifthere has been any intrusion of salt water into thefresh-water supply or if there is any danger of future intrusion.
