Some Hydrologic and Biologic Aspects of the Big Cypress Swamp Drainage Area, Southern Florida

H. Klein, W.J. Schneider, B.F. McPherson, and T.J. Buchanan

PURPOSE AND SCOPE

The prime purpose of the study of the hydrology of the Big Cypress, as expressed by the Secretary of the Interior in his news release of November 7, 1969, was to determine the importance of the Big Cypress in maintaining an adequate water supply for (1) the Everglades National Park, for (2) the expanding population of southwest Florida, and for (3) the adjacent estuaries, which constitute nurseries for fish, some of which are commercially important.

This preliminary report and the reconnaissance on which it is based were designed to provide the most essential available water and ecologic facts needed by the public and public officials in deciding upon the best utilization of the Big Cypress compatible with the broadening and somewhat conflicting needs of the people.

To define the role of the Big Cypress in the hydrology of south Florida, the following had to be determined, described, or delineated:

  1. Boundaries of the Big Cypress drainage area;
  2. Drainage features, flow patterns, directions of flow;
  3. Magnitude of water storage in and movement of water from the Big Cypress;
  4. Quality of the water and relation of quality to the biosystem;
  5. Changes in water movement and quality cause by land development to date;
  6. Possible effects of further land development on the water supply of the Big Cypress, the Everglades National Park, the nearby west-coast cities, and the adjacent estuaries.
